Definitions are a core part of any dictionary, and Wiktionary is no exception. Writing basic definitions requires some skill, more practice, and sometimes help.

First principles[edit]

There are a few basic guidelines to follow when writing a definition:

1. • Wiktionary is a dictionary, not an encyclopedia. A definition does not need to contain every piece of information known about a subject. Rather, it should contain information about the word and what the word refers to, and enough explanation to allow a user to distinguish that word from most other words.
   • Don’t include usage notes in a definition. If additional clarification is needed to separate a term from other words with a similar meaning, then Usage notes can be added.
2. Keep it simple
   • Write with simple grammatical structures rather than complicated ones. Limit the use of dependent clauses and phrases, whether set off by commas (or parenthetical). If many such additional modifications are needed in a definition, then that definition probably needs a thorough rewrite.
   • Place key terms and short explanations near the start of the definition. If a definition requires qualifications and modifying phrases, then try to place those near the end of the definition, after the main point has been made.
   • Avoid bombast, and get to the point. Padding an entry with superfluous verbiage may sound impressive, but that’s not the purpose of a definition.
3. Avoid complicated terms
   • Avoid terms that are more complicated or more technical than the term being defined. The purpose of a definition is to clarify meaning, not to obfuscate it.
   • Avoid polysyllabic monstrosities in the amalgamation of lexicographic phraseology. Don’t use big words if you can avoid them. They may be fun, but in a definition they tend to confuse people more than help them.
4. Avoid specialized terms
   • Use mainstream English words in explanations whenever possible. The more widespread a term is, the more users will benefit. Terms with restricted usage may leave a significant fraction of Wiktionary’s readership clueless.
   • Avoid jargon. Highly technical terms will probably require a user to look up many terms in the definition just to understand what it says. Although there are cases which require the use of a technical term in a specialized field, these should be kept to a minimum.
   • Avoid words whose use is restricted to certain geographic regions, social or ethnic groups, or that might otherwise leave many readers confused.
5. Avoid circularity
   • It is poor form to define a word with that same word in the definition. Use different terms.
   • Avoid defining a term solely using etymologically or morphologically related terms. Adverbs are especially prone to being defined by the adjective from which they derive. While it is possible to define words this way, definitions ideally should stand on their own.
   • Check the primary words in the definition to see whether any point right back at the term being defined. If two entries are defined solely or primarily as each other, then there will be no basis for a reader to understand either definition.

Style[edit]

Basic style[edit]

Numbering definitions: Each definition line should begin with a # (hash, octothorpe, pound sign). This will number the definitions. Place the hash at the leftmost position on the line, with no spaces or tabs prior to the hash. Additional definitions must be placed on a separate line, but there should be no blank lines within a group of definitions, since that will break the sequence of the numbering.

There are two basic styles of definition:

1. In explanatory style, beginning with a capitalized first letter and ending in a period.
2. translation style

Most English entries follow the first style, so that their definitions should begin with a capital letter and end with a period. In other words, such definitions are formatted as if they were sentences, even if they are actually sentence fragments. In contrast, most non-English entries follow the second style, since they typically translate the non-English word to one (or a few) English terms. However, there are non-English terms defined in the first style, especially when the term has no simple or straightforward English translation, and so it must be explained fully rather than just translated. When translating a word with a single English term, you can use template {{gloss}} to disambiguate the used term.

Definitions with more than one explanation: When a definition consists of more than one parallel explanation, the parts may be separated by commas or by semicolons. Commas are preferred in separating short and simple items, but semicolons are preferred when separating longer defining phrases or clauses.

Linking: One of the more powerful tools at Wiktionary’s disposal is the wikilink. Key terms in a definition should be linked by the use of double square brackets (i.e., [[word]]) around the term. This creates a link to the entry for that term.

Links should always be present around any word in the definition that is synonymous, or nearly synonymous with the term being defined. Likewise, link words which provide key descriptions or qualifications in defining a term. However, do not link every word in a definition. Linking all the words detracts from the visual emphasis that a wikilink provides, and creates visual confusion. Articles, prepositions, conjunctions, particles, and other short words should never be linked unless they are synonyms or translations of the term being defined.

When the explanatory style of definition writing is used, special care must be taken to link the capitalized first word in the definition. Wiktionary is case sensitive, so a simple link of the first word will often yield a red (broken) link, or may link to a German noun that happens to be spelled the same way. In these cases, the link must be «piped», as in the example: [[bridge|Bridge]]. This links to the first (lower-case) word while displaying the second (capitalized) word.

Part of speech variations[edit]

The wording in a definition depends on the part of speech of the word being defined. Nouns, especially proper nouns, are considered the easiest, followed by adjectives, and verbs. The most difficult words are included in the other parts of speech, especially those with purely grammatical functions like prepositions, conjunctions, determiners, articles, and particles.

Proper nouns[edit]

If a proper noun meets our standards for inclusion (WT:CFI), its definition should be relatively easy. If it seems to be difficult, insert a link to Wikipedia, follow the link to an article of that title if one exists or search for the term in other Wikipedia articles.

Other nouns[edit]

Concrete nouns are the next relatively easy class. Wikipedia may have an article. Wikicommons may have photographs or drawings. The insertion of photographs or drawings may reduce the need for users to rely on the words of a definition for the basics, allowing the definition to address questions of the boundaries of the term instead.

Abstract nouns are more challenging. Within this class the most challenging are core abstractions such as «time», basic emotions, etc. The easiest abstract nouns are those that are definable in terms of the most basic ones. Fortunately, few people will rely on a dictionary for the core abstractions. Definitions can be used to define the scope of the term, its boundaries, rather than attempting to define its essence.

Grammatical parts of speech[edit]

Grammatical parts of speech include all conjunctions, pronouns, determiners, prepositions, articles and particles, and most of the most common adverbs. Such words are often very hard to define in the same way as nouns, verbs, adjectives, and most adverbs derived from adjectives. If a particular word of this type cannot readily be defined, for example, by a synonym, consider a «non-gloss definition». Such a definition would typically begin with words such as «Used to indicate ….». Such a definition needs usage examples or citations even more than other definitions do. To facilitate review of such challenging definitions, please put the definition inside {{non-gloss definition}}.

Interjections[edit]

Interjections are not grammatical parts of speech, but also may not be easy to define. If a particular word of this type cannot readily be defined, for example, by a well-known synonym, consider a «non-gloss definition». Such a definition would typically begin with words such as «Used to express…», followed by a noun or noun phrase suggesting an emotion. Such a definition may need usage examples or citations even more than other definitions do. To facilitate review of such challenging definitions, please put the definition inside {{non-gloss definition}}.

Context tags[edit]

See Wiktionary:Context labels for details on context/usage tags.

• Wikihow to write a dictionary definition

While writing your essay, you may feel the passion for using specific words that could be challenging for the reader to understand what you are referring to. In this guide, we teach you how to define a word in an essay, on a text, sentence or within a paragraph.

In as much as you understand the easy topic inside out, the potential reader may hang while reading new vocabularies. 

It could be awkward if you write word-to-word definitions from your dictionary. Also, it could disorganize or be confusing if you use the definition in the wrong part.

The best way to use definitions effectively is by using your own words and remaining concise. You can opt to introduce definitions in the essay’s body instead of in the introduction. 

Before elaborating the word in definition terms, determine the word is unusual enough to require a definition.

While is it acceptable for you to define technical jargon in your essay, avoid defining every advanced vocabulary in the essay. 

Rephrase the definition with your own words. You must include a full quotation if you are word-to-word definition from the dictionary. For instance, you can make the sentence flow better by

defining a word like ‘workout’, as follows: “Workout is an exercise of improving one’s fitness and performance.”

If you are using in-text citations, you should cite the dictionary or the textbook that you took the definition from when you end the sentences.

When it is the first time you are using such a source, then use the full title backed by the abbreviation. By doing correct referencing of the definition source you used, you will be avoiding plagiarism in your essay. 

Let the definition be in the body and not the introduction since the introduction ought to catch the reader’s attention as you lay your thesis. Alternatively, you want to avoid defining a word, then use synonyms.

Keep the definition as short as possible. But, if you believe the definition could belong, then you can break it into shorter sentences to bring clarity to your essay. 

Do you want to explain something in the mid of the sentence without confusing the reader? 

While it is true that you may be harboring a lot of terminologies in your context that require some explanation, you must do it tactfully to promote the flow of your sentences well. 

There are three ways you can insert a definition in the mid sentences as provided by the following examples. 

1. By Using Commas

You can use commas as a way of punctuating your sentence to enhance the meaning. For example:

“John and Joseph had to see Bill gates, the leader of Microsoft Corporation, and advise him….”

2. Em and En Dashes 

They are not synonymous with hyphens but needed to punctuate your sentence and restore your intended meaning. For example, we can paraphrase the above sentence to appear as follows:

“John and Joseph had to see Bill gates — the leader of Microsoft Corporation — and advise him….”

3. Parenthetical Aside

It is also another suitable method to use when inserting a definition in the mid sentences to update the reader with additional facts. 

“John and Joseph had to see Bill gates (the leader of Microsoft Corporation) and advise him….”

How to Quote a Definition in a Sentence/Essay

When writing your essay, you will encounter such issues which are usually unavoidable. If we assume that you are using APA style for referencing, one must quote a definition inside double-quotes. 

That is “Definition” and put the author-year and page numbers. 

A definition in an essay examples

• McCarthy and George (1990) defined the essay as “a literary composition which represents author’s arguments on a specific topic.” P.87
• An essay is “a literary composition which represents author’s arguments on a specific topic.” (McCarthy and George, 1990, P.87)
• McCarthy and George (1990, P.87) defined an essay as “a literary composition which represents author’s arguments on a specific topic.”

Such definitions come in handy when you are writing essays that require you to understand one thing well. A good is example is when writing a comparison essay or a definition essay. Let us explore how to write a definition essay here.

Tips How to Write a Definition essay

A definition essay could be a piece of writing where you write your own meaning. One must ensure that you research your definition well and support it by the evidence.

In addition, it could be an explanation of what specific terms means in your context. This becomes a paragraph. Check out how to write good definition paragraphs and understand them from another perspective.

Some of the terms could have literal meanings like a phone, tablet, or spoon.

Other abstracts such as truth, love, or success will depend on the person’s point of view.

Different papers carry varying meanings hence when writing one, you must be precise to help the reader understanding what you are talking about. 

It could be reasonable if you remain unique as you write a definition essay. Avoid expressing meaning using the same words.

Before you choose a definition essay topic, ensure that you select an abstract word that has a complex meaning. Also, ensure that the same word is indisputable.

Tips How to Define a Word in a Text or Paragraph

1. Select a Word

The main point of view when writing an essay is selecting an idea or concept. Select a word that will describe an idea like Hate, Love, etc. ensure that you understand the term you are choosing completely. 

You can read from the dictionary but avoid extracting the definition from there but explain it in your own words.

Suppose your concept is open, then find your unique define based on experience. After that, find the basis to support your definitions. 

2. Select a Word That You Know

It is suitable to settle for the word that you are familiar with and you have a basic understanding of the word. Doing so helps you to write easily. For example, you can select a word like ‘pride’ because you understand its meaning and what it feels as you use it in your context. 

3. Select a Word With Different Meanings 

Selecting a word with plural meanings comes in handy when you believe it will bring a different meaning to various people. As you write about it, there is an opportunity to involve your understanding and interpretations of other people. 

For example, one can select a word like “love” because it comes with varying meanings. Every person will understand and interoperate it uniquely. 

4. Avoid Specific Things and Objects 

Stay away from selecting such things as “cups “or “pillow” because it complicates your writing because you cannot write a lot on specific objects. That makes the essay appear superficial and not shrewd enough.  

5. Go Online

With an internet connection, you can seek an online platform and get enough information about what you want. The internet has several scholarly academic blogs and articles.

Additionally, you can still access videos created by smart people who deeply researched different words and sharing them with you.   

6. Access the Dictionary 

It is true that every official word has a deeper dictionary meaning. Tactfully, it is vital that you familiarize yourself with yourself before using it in your contexts.

You must take a closer look at the definition structure before deciding to use it. Ensure that you explain it in your own understanding when writing about it. 

7. Know the Origin of the Word

Before using a specific word, it is critical to study and understand its origin. One way of researching the word is involving encyclopedias to get theories and ideas about that particular word.

For instance, if you are picking a word in the medical field, then you should consult the encyclopedia in the medical field.

8. Ask Colleagues  

While it is crucial to have your perspective about the word, you can still ask friends and family about the meaning of that particular word.

Let them explain to you what it feels when you mention such a particular word. Later, you can record the answers and utilize them as your sources.

The Basics of Definitions

Before we get into how to write a definition, you need to know a bit about definitions themselves, and how to spot good and bad definitions.

Once you know that, we’ll walk you through the five steps to creating a good definition.

Then we’ll teach you how to apply and extend those steps to craft different types of definitions.

So let’s start at the very beginning, shall we?

Using Words You and Your Audience Know

Ya know, this seems pretty obvious – almost so obvious it shouldn’t be the first thing you read in a book about how to write definitions. But it has to be said. It has to be said because all too often we read something in our business lives (not so much for entertainment, thank the universe) that just doesn’t make sense. In some instances, the author wants to «sound smart» by using «big words». As an example, here’s a student’s paper that I read the other day:

«The dialectical interface between neo-obstructionists and anti-disestablishment GOPers is stuck in a morass of quibbling over pettifog.»

The paper was about discussions between students and lawmakers over stricter gun laws for assault weapons. The sentence, in plain English, reads as this:

«The logical discussions between student protesters and Republican lawmakers resisting change are bogged down because of arguing over petty things.»

In some instances, the author just uses the wrong words. One famous example, used in many word choice articles, is as follows:

«Cree Indians were a monotonous culture until French and British settlers arrived.»

What the author meant was that Cree Indians were a homogenous culture. 

So, before we get started on a conversation about definitions, when picking your words, if you run across words you don’t use often, ask yourself these basic questions:

1. Can I spell the word correctly? Here’s a hint: Open your favorite word processor and make sure active spell-checking is turned on. Then type the word. If it comes up with an underline, your dictionary doesn’t recognize it. Most word processors will allow you to Control-Click or Right-Click the term and look up a spelling suggestion.
2. What does this word mean? Second hint: Research the term online and find a consistent meaning. If you can’t readily find a definition for the term don’t use it. Try looking up the definition of «dialectical interface» above. If you find a definition, email the team at info@unifiedcompliance.com. We’d love to see it and know where you found it.
3. Will the people I’m communicating with know what this word means? Will they have the same understanding of the meaning that I do? Third hint: Ask a few people who might read your writing if they know what your term means. You’ll be surprised at the varied answers. We did this once with government writers working on a cybersecurity manual. We asked for the definition of Cybersecurity. Twelve people, thirteen answers — all different. One guy wrote two answers because he wasn’t confident of either one of them.
If you don’t know what you are talking about, no one else will either.

What Happens When We Communicate

To understand what’s happening when we communicate, we need to understand what a concept is, what a term is, and what an instance means. Let’s start this discussion with a quick illustrative point. 

You and I are sitting at a table. In front of us is the plate in the diagram that follows. One of us is from Chicago, the other from London. I say to you, «may I have a biscuit?» Your answer is «of course». I then pick up which item(s)?

If I were from Chicago, that plate would contain one biscuit and two cookies. If I were from London, that plate would contain one scone and two biscuits. What’s going on here is:

1. we see two sets of instances of some type of food in front of us;
2. those two instances are formed as concepts in our mind;
3. and when we communicate about those concepts, we communicate them as terms.

The concept of the big, soft, flaky, doughy thing has generally been given the term scone in England and biscuit in the US. The concept of the drier, smaller, crunchier things has generally been given the term biscuit in England and cookie in the US. When I asked for the biscuit, I’ve identified the term and the conceptto me. It’s when I reach for the biscuit that I tie the instance and the name together for both of us. 

And that’s where the fun starts. You look at me and say, «hey, I thought you wanted the biscuit/scone» (depending on where you are from). I would explain, «yes, and I took one». We would both be baffled at the lack of the other’s comprehension of what we know to be true. 

If we were friends, we’d probably continue with «I thought that was called…» and then add the term that goes with the concept in our mind. A quick sharing between us would bring out both concepts, both definitions of what we think we are looking at. And we’d do the same, probably, for the cookie/biscuit concepts of the instances we see. 

This is why it is important to know how to write good definitions, but more on this later. We took an instance from reality and stated the term we have given to the definition of its concept. We have, for one bright shining moment, communicated with each other. Being from Chicago, while living in London for a period of time, I ended up simply using the definitions of things I’d point to; «can I have one of those  fluffy pastry things there…» I’d ask at the bakery. 

This is why defining your term is important.

The Importance of Defining Terms (part one)

There is a quote attributed to George Bernard Shaw that follows along the lines of, «Britain and America are two nations divided by a common language». Whether or not the attribution is or isn’t Shaw’s, the point is that even though we use the same words, those words can (and often do) have quite distinctly different meanings because of our cultural differences1. There’s even a British English vs. American English translation dictionary2!

To put it short and sweet — words, the terms we use, do not have one correct meaning. Words can mean different things at different times. They come into existence to express thoughts by a group of people that share them, at a point in time, with a meaning that reflects their origin, use, and timeframe. 

Take, for instance, the word awful. Originally, that word meant «worthy of awe», as in «very inspiring». However, over time it has come to mean bad, displeasing, offensive, etc. A quick Google search will produce list upon list of terms that have changed over time3. More specifically, the words and phrases that you find in a dictionary exist to express these shared thoughts, which we’ll refer to as concepts throughout this document. 

We won’t go into the philosophical debate of whether concepts define words or words define concepts, a debate that is currently plaguing educators today4, as it has been since the times of Plato and Socrates5. Nor will we spend time debating about specific definitions of terms, how the definitions morph over time, or the nature of, and demands on, definitions6. 

Instead, this document will focus on how to fulfill the need to establish and maintain definitions for specific terms within specific subject fields7. There is an entire international standard dedicated this pursuit8, from which we have drawn much of our inspiration. The issue we are attempting to remedy in this document, is the tendency of each subject field to create its own sub-language of specific terms and their definitions. These terms might be shared with other subject fields, but quite often the definitions for these shared terms are different. And just as often, those in specific subject fields create new, distinct terms used to describe the same concept as other terms found in other subject fields. So, we end up with this:

Same words — different definitions.

Same definitions — different words.

If you want a real-word example, perform this Google search:

What is personally identifiable information?

The last time we performed this search, Google returned over 1.7 million entries with well over 100 definitions (we stopped counting about then)9. With this huuuuuuge list of potential definitions for a key term such as Personally Identifiable Information, you have to agree with us that the only way you can share your meaning is through how you use the term. Better yet, you can provide a definition for the key terms you are using. In short, if you define your key terms, you’ll clarify the concepts behind the terms you are using in that argument, in that document you wrote, or if they are added to some custom dictionary, in that specific field the dictionary covers.

The Importance of Defining Terms (part two)

Yes, certain words have multiple meanings. We’ve covered the reason to define which meaning you are using if you think those you are communicating with will be befuddled. That’s one reason to define what you are saying. The other is when you are creating new words. And let’s face it — we do that more of-ten than you’d think. 

When we wrote about using words your audience doesn’t know it was because we were pointing out you didn’t know either. If you find yourself in a place where you are using words that others don’t know — look up those words to see if someone has given them a definition. Look it up online and find a consistent meaning. If you can’t readily find a definition for the term, then define it! Where do you think dictionary definitions come from? You. Me. Them. Everybody! (Everybody, needs somebody! Everybody — needs somebody to define! he laughingly sings…) 

Dictionaries are historical references There. I said it. But more importantly, so did John Simpson, former Chief Editor of the Oxford English Dictionary. Here’s a passage (edited for clarity) from a book he recently wrote10:

«It is easy to be too precipitate in selecting a word for inclusion in the dictionary… In general, we learned to shy away from trying to define any new word – wherever possible — until it had a chance to settle down in the language…it is helpful for us to see whether others publish preliminary accounts of the word from their own impressions or research. That’s not cheating; it’s just good research sense.»

The simple point is this — if you want to use a term you can’t find a definition for, you need to write that definition. And the great part is, if it is your word, your definition can’t be wrong! These types of definitions are called Stipulative definitions, and we’ll cover them in a bit.

What is a Definition?

In its simplest form, a definition is “a statement of the meaning of a word or word group or a sign or symbol1”. In other words, a definition explains through clarification and further explanation what we are trying to say with one or a few short words. Aristotle would say that the definition provides the essence (ὁρισμός horismos) of the term2.

Well, that’s nice, but it isn’t that helpful unless you are a philosophy major who can spout out what essence means as part of dinner conversation. And even if you wanted to we’d rather you just stare blankly at your iPhone. 

So, to start this off, let’s look at an example of a bad definition, one that just doesn’t fit the essence of the term it is supposed to describe. In our research we come across a great deal of bad definitions, many of which are found in published glossaries. 

For example, a technical glossary from the United States’ National Institute of Standards and Technology, their Glossary of key Information Security Terms, defines the term Computer Security Incident Response Team (CSIRT) as — a capability set up for the purpose of assisting in responding to computer security-related incidents. This term, absent of the definition, and because it describes a team, brings to mind a group of people who respond to computer security incidents. However, the presented definition egregiously leaves out the entire essence of team and replaces it with capability. Although the team in this definition should be comprised of individuals who possess the capability to respond to security incidents, the definition fails by mistaking a group for a capability.

How to format a well-written definition

All of the reading we’ve done, all of the research we’ve done, except for Purdue’s Online Writing Lab example13 (which states you need to always start with the term, which we will ignore), breaks a definition down (roughly) into two parts, as shown below:

category of concept + differentiating characteristics

Or if you like to use scientific words:

genus + differentia

Category (genus)

This defines the category or class your concept fits into. In essence, you are relating the term to its broader category so that your audience says, “yeah, I know what those are”.

Differentiating Characteristics (differentia) These are the specific characteristics that set your term apart from other terms within that category. Once you’ve related your term to the broader category, now you are saying “well, it’s like those things, but with these differences.” 

Most often, the category of the concept is presented first, followed by the differentiating characteristics. Other types of definitions will lead with what differentiates the concept and then show how it fits into the broader category. The best way to bring this point home is to give you some examples of the different types of definitions that are out there, using terms that we should all be familiar with. By doing this, we’ll be able to give you the definition and then point out how it was formulated. 

Let’s say that we were going to describe a Zebra using this method. We would say that a Zebra was a mammal in the family of Equidae (Equus) with black and white stripes and an erect mane.

If this were a conversation, you might be stating it like this; “Hey, you know what a horse is, right? Well this is in the family of horses, but they Zebras have black and white striped coats and short manes that stand straight up.” You are equating it to something they know and then adding the differences for this particular concept or thing. This is the basic form of a definition. 

Of course, folks can’t leave well enough alone, so they’ve created several kinds of definitions that you can either delve into or skip over.

The Various Types of Definitions

The wild thing about definitions is that there are many different types of definitions, each used to explain a particular type of concept. However, the two most general types of definitions are intensional and extensional definitions.

What are the two general kinds of definitions?

There are specific types of definition forms we’ll cover in a minute. But first, we need to start with the most used forms of definitions, intensional and extensional. Let’s look at defining what we see in the illustration that follows:

Intensional definitions

An intensional definition specifies the necessary and sufficient set of features or properties that are shared by everything to which it applies.

Term	Definition
Baked Goods	Foods that are cooked in an oven of some fashion that uses prolonged dry heat, and are usually based on wheat flour or cornmeal.

In this first definition, we see that the category portion of the definition is “foods that are cooked in an oven”, followed by the differentiator of being “based on wheat flour or cornmeal”. It is both necessary and sufficient for anything being baked to be cooked in an oven of some fashion. 

Intensional definitions are best used when something has a clearly defined set of properties and hastoo many referents to list in an extensional definition. For instance, you would want to use an intensional definition to define business records, as a business record is a document (hard copy or digital) that records a business dealing. To attempt to enumerate each and every type of business record would be nearly impossible.

Extensional definitions

The opposite of an intensional definition, an extensional definition is usually a list naming every object (or at least enough of a list to create clarity in the reader’s mind) that belongs to the concept.

Term	Definition
Baked Goods	Breads, cakes, pastries, cookies, biscuits, scones, and similar items of food that are cooked in an oven of some fashion.

This example presents the individual differentiators first (“breads, cakes, pastries, cookies, biscuits, scones”) that belong to a common category, “cooked in an oven”.

Beyond the two basic types of definitions, there are several other notable definition types that can be employed. We’ll cover them now.

What are stipulative definitions?

This is used when you make up a term for the first time. This means that you’ve completed all of the research necessary and can’t find that term anywhere. It is your assignment of meaning to your term. The illustration below shows two scones, a plain scone on the left and a Charlotte’s Sprinkle Scone on the right.

Here are a couple of different takes on writing a definition that you’ll see sometimes, the partitive definition and the encyclopedic definition. To show the differences, we’ll define yeast, first as a part of something, and then provide a more, exhaustive, definition.

What are partitive definitions?

These are definitions that explain the concept as being a part of a greater whole; the distinct part(s) of a more comprehensive concept.

Term	Definition
yeast	As a key ingredient for most baked goods that is commonly used as a leavening agent in baking bread and bakery products.

Notice here that this definition begins by saying that the yeast is “a key ingredient”, or part of the category “baked goods”, then adds the differentiator for the part it plays: “leavening agent”.

What are functional definitions?

These are definitions that explain the actions or activities of the concept in relation to the more comprehensive concept.

Term	Definition
yeast	An ingredient that is commonly used as a leavening agent in baking bread and bakery products.

This definition focuses on what yeast does within the baking process.

What are encyclopedic definitions?

These are definitions that go beyond the requirements of definition. Not only do these types of definitions provide the context and characteristics of the concept, they provide additional information about the concept as well.

Term	Definition
yeast	As a key ingredient for most baked goods that is commonly used as a leavening agent in baking bread and bakery products, where it converts the fermentable sugars present in the dough’s gluten into carbon dioxide and ethanol, thus trapping the releasing bubbles of gas into the gluten and making the dough fill up like a balloon as it rises.

As with the partitive definition, this definition begins by saying that the yeast is “a key ingredient”, or part of the category “baked goods”, then adds the differentiator for the part it plays “leavening agent”. It then goes on to add how yeast works to make the dough rise as part of the definition. You don’t really need to know how yeast works to understand that it’s a leavening agent, unless you don’t know what a leavening agent is and don’t want to look it up.

What are theoretical definitions?

A definition that is really a scientific hypothesis in disguise. It attempts to present an argument for a concept. Here’s a rare and I think erudite theoretical definition of a US scone that we found.

What are synonym definitions?

Then there are the very simplistic synonym definitions. These definitions use synonyms of the concept to describe the concept. They are normally used when you need to define instances of a concept in a simple fashion.

Types of Definitions Cheat Sheet

Okay, we’ve gone over all of the various types of definitions. You’ll want to keep this cheat sheet around so that you have a shortened version of what should go into each type of definition.

Intensional definitions (genus + differentia)

Begins with the category, or properties and features shared by other concepts or things like it.

Continues with what makes this concept or thing different than the other members of its category.

Extensional definitions

Lists as many objects, properties, or features as necessary that represent the concept or thing being described.

Explains how those objects, properties, or features fit into a more generalized category.

Lexical definitions

Begins with the setting, how the term is used in the document(s) it is drawn from, or the audience it is aimed at.

Places that setting into the context of the category, or properties and features shared by other concepts or things like it.

Continues with what makes this concept or thing different than the other members of its category.

Partitive definitions

Begins by describing this particular concept or thing as a part of a greater whole.

Continues with the category that the greater whole fits into.

Adds what makes this concept or thing different than the other parts of the same greater whole.

Functional definitions

Begins by explaining what the concept or thing does.

Continues by explaining how that role fits into a larger category with properties and other functions like it.

Encyclopedic definitions

Begins with the category, or properties and features shared by other concepts or things like it.

Continues with what makes this concept or thing  different than the other members of its category.

Provides additional classification, history, etc. about the concept or thing for elucidation purposes.

Theoretical definitions

Begins with the category, or properties and features shared by other concepts or things like it.

Continues with what makes this concept or thing different than the other members of its category.

Continues with the theory of why this concept or thing fits into the category or why the differentiators are important.

How to Test Existing Definitions

Searching Google for a definition will almost undoubtedly return multiple definitions for the same term. And it isn’t just Google returning too many definitions. Many organizations that create glossaries for their documents are very sloppy with their terms – even the US National Institute of Standards and Technology! 

Just because someone wrote a definition, that doesn’t mean it’s correct. Heck, if the United States’ own National Institute of Science and Technology can write some pretty bad definitions in their glossaries, anyone can write bad definitions in theirs.

The test forms

Here are some forms for you to use when examining various definitions. We’ll use these forms to examine a few terms below.

Intensional Definitions

Term Definition Question Y/N Reason Does the definition begin with the category, or properties and features shared by other concepts or things like it? Does this categorization make sense? Is the categorization blatantly wrong? Does the definition continue with what makes this concept or thing different than the other members of its category? Do all of those things that make it different belong to this concept? Extensional Definitions Term Definition Question Y/N Reason Does the definition list as many objects, properties, or features as necessary that represent the concept or thing being described? Do some of the items in the list not fit with the other items in the list? Does the definition explain how those objects, properties, or features fit into a more generalized category? Lexical Definitions Term Definition Question Y/N Reason Does the definition begin with the setting, how the term is used in the document(s) it is drawn from, or the audience it is aimed at? Does the definition that setting into the context of the category, or properties and features shared by other concepts or things like it? Does this categorization make sense? Is the categorization blatantly wrong? Does the definition continue with what makes this concept or thing different than the other members of its category? Partitive Definitions Term Definition Question Y/N Reason Does the definition begin by describing this particular concept or thing as a part of a greater whole? Does the definition continue with the category that greater whole fits into? Does the definition add what makes this concept or thing different than the other parts of the same greater whole? Functional Definitions Term Definition Question Y/N Reason Does the definition begin by explaining what the concept or thing does? Does the definition continue by explaining how that role fits into a larger category with properties and other functions like it? Does the function belong to this category? Encyclopedic Definitions Term Definition Question Y/N Reason Does the definition begin with the category, or properties and features shared by other concepts or things like it? Does the definition continue with what makes this concept or thing different than the other members of its category? Does the definition provide additional classification, history, etc. about the concept or thing for elucidation purposes? Theoretical Definitions Term Definition Question Y/N Reason Does the definition begin with the category, or properties and features shared by other concepts or things like it? Does the definition continue with what makes this concept or thing different than the other members of its category? Does the definition continue with the theory of why this concept or thing fits into the category or why the differentiators are important? Testing terms In researching terms relating to cybersecurity (a topic very close to our organization’s heart), we found that everyone agrees on what the definition of cyber means, but there are two different definitions of security, and eight definitions of cybersecurity. So let’s go through the process of analyzing their definitions using the rules for testing the definitions that we listed above. Testing Cyber Term Definition Intensional Questions Y/N Reason cyber The interconnected information infrastructure of interactions among persons, processes, data, and information and communications technologies, along with the environment and conditions that influence those interactions. Does the definition begin with the category, or properties and features shared by other concepts or things like it? Y That’s the part in the definition where it says “interconnected information infrastructure of interactions” – cyber at Dictionary.com reiterated the computer-connectedness of the category. Does this categorization make sense? Is the categorization blatantly wrong? Y Absolutely. Does the definition continue with what makes this concept or thing different than the other members of its category? Y It includes, mostly, the gamut of who and what is interconnected. Do all of those things that make it different belong to this concept? Y So we know that cyber works. The category works; the specifics work. Testing dictionary vs. glossary definitions of security We recently ran into two different definitions of security in two different glossaries. Both were much wordier than the dictionary definition of security. One, though wordy, was a good definition. The other, also wordy, had the wrong category altogether. Term Definition Intensional Questions Y/N Reason security (dictionary) Any measure that makes safe, protects, or defends something or someone. Does the definition begin with the category, or properties and features shared by other concepts or things like it? Y The category here are all measures. Does this categorization make sense? Is the categorization blatantly wrong? Y Does the definition continue with what makes this concept or thing different than the other members of its category? Y Measures that make safe, measures that protect, measures that defend. Three differentia. Do all of those things that make it different belong to this concept? Y Functional Questions security (glossary 1) A condition that results from the establishment and maintenance of protective measures that enable an enterprise to perform its mission or critical functions despite risks posed by threats to its use of information systems. Protective measures may involve a combination of deterrence, avoidance, prevention, detection, recovery, and correction that should form part of the enterprise’s risk management approach. Does the definition begin by explaining what the concept or thing does? Y It explains how the condition of being secure is met through the various protective measures. Does the definition continue by explaining how that role fits into a larger category with properties and other functions like it? Y The second sentence is about all of the properties of “protective measures” that can be included. Does the function belong to this category? Y Intensional Questions security (glossary 2) The protection of computer facilities, computer systems, and data stored on computer systems or transmitted via computer networks from loss, misuse, or unauthorized access. Computer security, as defined by Appendix III to OMB Circular A-130, involves the use of management, personnel, operational, and technical controls to ensure that systems and applications operate effectively and provide confidentiality, integrity, and availability. Does the definition begin with the category, or properties and features shared by other concepts or things like it? Y It does begin with a category but see below. Does this categorization make sense? Is the categorization blatantly wrong? N If you read the second sentence, it says computer security. So when you go back and re-read the first sentence, the category makes sense if it was computer security but doesn’t make sense as a broad definition of security. Testing definitions of cybersecurity Much like the definition of security, we found multiple definitions of cybersecurity. It’s almost laughable that each and every glossary we encounter with cybersecurity in it, we encounter yet another different definition of the term. Let’s put the definitions to the test.
Term Definition Intensional Questions Y/N Reason cybersecurity (glossary 1) Any measure used to protect or defend the use of cyberspace from cyber attacks. Does the definition begin with the category, or properties and features shared by other concepts or things like it? Y The category here, like with the first definition of security, is measures specific to cyberspace. Does this categorization make sense? Is the categorization blatantly wrong? Y Does the definition continue with what makes this concept or thing different than the other members of its category? Y Measures that protect and defend against cyber attacks. The measures fit the category. Do all of those things that make it different belong to this concept? Y Intensional Questions cybersecurity (glossary 2) The process of protecting information by preventing, detecting, and responding to attacks. Does the definition begin with the category, or properties and features shared by other concepts or things like it? Y The category is about the process of protecting, information. Does this categorization make sense? Is the categorization blatantly wrong? N It begins with a general security category of protection but skips the whole cyber aspect of it. Does the definition continue with what makes this concept or thing different than the other members of its category? Y It has the differentiator of “preventing, detecting, and responding to attacks” Do all of those things that make it different belong to this concept? N The differentiators are coupled with information protection. This really says that the definition is about information security and not cyber security. Functional Questions cybersecurity (glossary 3) The protection of information assets by addressing threats to information processed, stored, and transported by internetworked information systems. Does the definition begin by explaining what the concept or thing does? Y Addressing threats to processed, stored, and transported information. Does the definition continue by explaining how that role fits into a larger category with properties and other functions like it? Y It links these as a part of internetworked information systems. Does the function belong to this category? Y As we learned with the term cyber, internetworked information systems fits that category.

Analyzing definitions isn’t that hard. Look for the term to fit a general category. Look for the differentiators. Follow the other questions for each of the definition types. You’ll be fine.

How to Write Simple Definitions

There are three steps to follow for creating simple definitions.

1. Research the term. If you find an existing definition that you like, use it (and cite the original author). If not, then follow the rest of these steps.
2. Determine what the term’s concept is. Is it a noun, verb, pronoun, etc.? Or is it more distinct, some type of named entity? This designation will format your definition’s focus.
3. Choose the definition type that fits. Intensional, extensional, partitive, etc. Then craft the definition to fit the designation and subject matter using a standardized format.

---

Step 0 – Limit Your Definitions to a Single Concept

If you can’t define the term in your mind to a single concept, then split the concepts into separate definitions. Think of report as both the sound of gunfire and calling the police to tell them about the sound of gunfire. That’s two definitions. One is a noun (the sound) the other is a verb (the act of calling or reporting). You have to define one concept at a time.

---

Step 1 — Research the Term

Here’s the scenario, you are writing whatever document it is and you’ve determined that you want to create a definition in your document. But your organization doesn’t have a definition for that term that you can draw from. So your first step in how to write a definition is to see if there’s a definition readily available that you can leverage (and cite so you aren’t plagiarizing). 

The Unified Compliance team is in that predicament quite often. Where do we find the definitions? What methods do we use to look for them? Our methodology works its way down from the most authoritative sources to the least authoritative sources. From absolute definitions down to definitions you will have to build out yourself (following standards set forth by international committees).

Searching dictionaries for single words

You might have luck searching the Oxford English Dictionary, Merriam-Webster, or any other host of online dictionaries for single-word terms.

However, searching for phrases, especially technical phrases, won’t work really well with this list of dictionaries. For that, you’ll need to follow a different set of practices.

Searching dictionaries for phrases

Here’s a couple of realworld scenarios for you from a technical document we were working with. The bolded terms are the ones you’d need to search for.

Use session lock with pattern-hiding displays to prevent access/viewing of data after period of inactivity.

Authorize remote execution of privileged commands and remote access to security-relevant information.

With these two sentences, we now have the following phrases:

• session lock
• pattern-hiding display
• period of inactivity
• remote execution
• privileged command
• remote access
• security-relevant information

Both Cambridge and Merriam-Webster found one of the terms listed above (remote access). However, none of them found the rest of the terms. Therefore, you’ll need to turn to searching more technical dictionaries and glossaries for phrases such as these.

Dictionary	URL
webopedia	http://www.webopedia.com/
TechTerms	https://techterms.com/
Computer Dictionary	http://www.computer-dictionary-online.org/
Free Online Dictionary of Computing	http://foldoc.org/
Business Dictionary	http://www.businessdictionary.com/definition/
Investopedia	http://www.investopedia.com/dictionary/
TechTarget’s Dictionary	http://whatis.techtarget.com/
The Law Dictionary	http://thelawdictionary.org/

Even when searching the technical dictionaries above, however, only one term was found in one dictionary – “remote access” in webopedia. This means that you’ll need to turn to broader search engines, about 90% of the time. We’ll cover how to use search engines next. For now, if you were lucky enough to find the definition, save the URL. You will need to add it to the definition as the source of where the definition came from.

Searching Google for phrases

The bad news is that over 90% of the terms you are going to have to add to the dictionary are phrases that don’t exist in any known glossary or dictionary entry. As of this writing, most document authors fail to provide definitions for their key terms. Don’t worry yet, there’s one more search capability at your fingertips – searching Google’s definitions.

Here’s how to do it: 

• Enter terms in both singular and plural form.
• If a term has a hyphen, search for it with and without the hyphen. 
• Use is and are — 

The last step is important, because you are looking for definitions written within a document and not in a glossary entry or definition of terms section. These definitions will be written within the context of the document’s content itself. Therefore, authors are most likely to state the terminology as saying, “X is this” or “many Ys are that”.

Base Term	Single form	Plural form
session lock	define “session lock is”	define “session locks are”
period of inactivity	define “period of inactivity is”	define “periods of inactivity are”
security-relevant information	define “security-relevant information is”define «security relevant information is»

As an example, searching define “session lock is” turns up uses of the term, but no real definition of the term as shown in the diagram that follows:

One of our researchers, Steven Murawski, adds that he has found some sticky definitions by typing «session lock» meaning or «session lock» definition. It only works about 10% of the time, but it is worth noting if you can’t find anything else. If you found the definition, save the URL. You will add it to the terminological entry as the source of where the definition came from.

This methodology works great for a few of the terms in our list. However, there wasn’t a single source that we searched for which had a solid definition for pattern-hiding display. So what do you do when you can’t find a source that specifically defines the term? You build the term’s definition following a well-defined international standard for doing so.

---

Step 2 — Determine the Term’s Concept

The first thing you need to do is to place your term into the proper context. If you are in a discussion and need to define your term, you’ll be thinking about the discussion you are having, and what types of concepts are being bandied about. If you are writing a document, you’ll probably need to narrow the concept down to one. 

We’ll stick with you writing a definition for a document, and we’ll use the term pattern-hiding display. The document you are working with will form the subject field for the broadest context you are going to work with. The citation, no doubt, falls within a section of that document. And sections are broken down into various contexts within the document. Within that section, the Citation will provide the most specific context you are dealing with.

Now let’s look at the phrase pattern-hiding display within the context of the document, the Section, and the Citation it was found in.

What	Context
Information Security Policy	Protecting Information
Section 3.1	Using Access Controls
3.1.10	pattern-hiding displays protect information by preventing viewing of data

From this, we know that the context is about hiding information from view as a form of access control that protects information. Got it. 

We know from our document that pattern-hiding displays are covered in the section on access controls. So we are pretty certain that the general category for our term is going to be access control. But on looking up the definition for access control, we found that it can cover physical access, computer system access, and information access as well. So we have several subcategories of access control that exist.

So let’s start a worksheet for adding the term, the term’s possible category, and any possible subcategories that we know of. Then we’ll see if they fit.

Term	Category	Subcategory	Fit?
pattern-hiding display	access control	physical assets	N
		computer system	N
		information	Y

In our context, neither computer system nor physical assets fit our genus. Therefore, we know that the context we are dealing with is information access control. 

But what type? That’s found in the attributes.

Identifying the attributes of the term

Now that you have the general category for the concept, you must examine the language for its attributes. 

When we talk about attributes in this document, we specifically mean the distinguishing features as derived from the words used and the context in which they are used.

Because you are going to be dealing with terms you’ve found in a Citation, the attributes are really the individual terms you are dealing with within the context of the document you are working with. If you have two words in a phrase, you have two attributes. In our scenario, we have two words: pattern-hiding and display. Our attributes for this term are threefold:

• information protection mechanism (from the context)
• pattern-hiding (from the term)
• display (from the term)

We now need to search for each term in the various dictionaries and check to see if there are any definitions that fit our context of information access control that we are dealing with. Searching dictionaries for either pattern-hiding or pattern hiding produces nothing on its own. Searching the web for either one produces some rough definitions of algorithms and software methodologies to obscure numbers or images on a screen.

Term	Category	Subcategory	Fit?
pattern-hiding	session lock	Concealing information previously visible on a display.	Y
	prime number	Artificial numeric patterns that are embedded with previously thought to be random numbers.	N
	screen saver lock	The capability, when the computer is locked, to set the screen to black or display selected or random images or numbers.	Y

Searching for display gives us a bunch of definitions. One of which is a computer monitor, another of which is the process or facility of presenting data or images on a computer screen or other device. Within the context of the Citation and its section, we can conclude that the characteristic isn’t about the monitor per se, but about the ability to display data or images.

Term	Category	Subcategory	Fit?
display	art	A performance or show.	N
	assets	An electronic device for the visual presentation of data.	N
	computing	Process or facility of presenting data or images on a computer screen or other device.	Y

We now have a comprehensive view of what our concept is and are one step closer to writing a good definition.

Step 3 — Choosing the Definition Type

You need to start with the designation for the definition. You can’t define the concept unless you know what type of concept you are defining. Let’s put the research we’ve done into this section as a reference for our work here.

Term	Category	Subcategory	Attribute
pattern-hiding display	access control	information
pattern-hiding		session lock	Concealing information previously visible on a display.
		screen saver lock	The capability, when the computer is locked, to set the screen to black or display selected or random images or numbers.
display		computing	Process or facility of presenting data or images on a computer screen or other device.

Choosing the definition designator

Designations are attributed to the concept you are defining, not the individual term. 

Designations for definitions fall into two categories: parts of speech designations and named entity designations. 

1. Parts of speech are noun, pronoun, adjective, determiner, verb, adverb, preposition, conjunction, or interjection. 
2. Named entities can be any of those entities we’ve already named; asset, data contents, events, group, organization, organizational function, person, record example, role, or title. Or they can be additional named entities that you have defined. 

We will ignore named entities for now and discuss parts of speech. From our research here, we know that this isn’t a verb. It’s a noun. Simple.

Term	Designator
pattern-hiding display	noun

Deciding on a definition type

Now it’s time to go back to the cheat sheet. We listed seven different definition types. We are going to ignore all except the intensional definition because we are starting with simple definitions here. So we know that we’ll first be defining the genus of the term and then adding its differentia. We’ll do that in our worksheet for each of the attributes that we have.

Term	Designator	Genus	Attribute
pattern-hiding display	noun
pattern-hiding	noun	session lock mechanism	conceals information previously visible on the display
	noun	screen saver mechanism	sets the screen to black or displays selected or random images or numbers
display	verb	computing	presenting data or images on a computer screen or other device

How to format your definition

This is really just a matter of putting everything together.

Term	Designator	Genus	Attributes
pattern-hiding display	noun	A session lock or screen saver mechanism that	conceals information previously on the display by
			setting the screen to black, or
			displaying selected or random images or numbers.

And there you have it, you have learned how to write a definition. A pattern-hiding display is a session lock or screen saver mechanism that conceals information previously on the display by setting the screen to black or displaying selected or random images or numbers.

How to Write Advanced Definitions

There are six steps to follow for creating advanced definitions. The first three steps are the same as creating simple definitions, so we’ll skip these steps in the documentation that follows.

1. Research the term. If you find an existing definition that you like, use it (and cite the original author). If not, then follow the rest of these steps.
2. Determine what the term’s concept is. Is it a noun, verb, pronoun, etc.? Or is it more distinct, some type of named entity? This designation will format your definition’s focus.
3. Choose the definition type that fits; intensional, extensional, partitive, etc. Then craft the definition to fit the designation and subject matter using a standardized format.
4. Formalize the way you name the term.
5. Add semantic relationships to the definition to connect it to other terms.
6. Review your definition with your team and test it.

---

Step 4 — How to Formalize the Term Entry

We’ve already covered how to write definitions, the communication of the concept of an instance we see or think about. We’ve covered some pretty basic rules about definition types and what should and shouldn’t be in them. Now we have to cover a few rules about how to express the term itself. 

Why do we have to set rules? 

Because many people who create glossaries are just plain sloppy (they probably don’t even make their beds in the morning). They’ll have plural forms. Capitalization where none is called for. Unconventional spelling. And – most egregiously – they’ll also include acronyms as terms themselves. 

Ugh. 

In order for modern electronic glossaries and dictionaries to work with Natural Language Processing engines, the following rules for entering the term itself should be followed.

Enter terms as a base form only

If you aren’t aware, nouns and verbs have a base form and additional forms. Here they are:

Base Form	Other Forms
Singular Non-Possessive Noun	Possessive
	Plural
	Plural Possessive
Simple Present Verb	Past
	Past Participle
	Present Participle
	Third Person

Here are the rules for both nouns and verbs.

What are noun entry rules?

• • All nouns are entered as singular (check irregular nouns).
  • Remove all apostrophes from the last word in a term or phrase.
  • Enter the term or phrase in lowercase unless it is a proper noun
  • All terms with “non” in them should have the dash “non-” unless specified in the Oxford English Dictionary

  NO acronyms should be added as terms, unless this is an acronym dictionary

What are noun pluralization rules?

Most nouns are pluralized by adding an –s to the end of a word. There are seven other pluralization rules that depend on what letter(s) the noun ends in.

1. Most nouns add s to the end.

Examples: cat – cats; car – cars; team – teams

1. If the noun ends in -ch, -sh, -s, -ss, -x, or -z  add  -es to the end

Examples: church – churches; tax ­­­­– taxes; pass – passes

1. If the noun ends in -for -fe change -f or -fe to -ves

Examples: elf – elves; loaf – loaves; thief – thieves

1. If the noun ends in a vowel and -y add -s to the end

Examples: toy – toys; boy – boys; employ – employs

1. If the noun ends in a vowel and -o add s to the end

Examples: video – videos; studio – studios; zoo – zoos

1. If the noun ends in a consonant and -y change -y to -ies

Examples: baby – babies; country – countries; spy – spies

1. If the noun ends in a consonant and -o add -es to the end

Examples: hero – heroes; potato – potatoes; volcano – volcanoes 

NOTE: Irregular nouns follow none of these rules.

What are verb entry rules?

When adding verbs to the dictionary, ensure that you follow these rules:

• Verbs are entered in simple present tense
• Remove any conjugations. (check irregular verbs)
• Enter the term or phrase in lowercase.

What are verb conjugation rules?

Most verbs are conjugated by following these rules.

1. Past tense: add –d,-ed, or –t to end of verb
2. For verbs ending in –y change –y to -i and add -ed
3. Past participle: add -d or –ed or –t to end of verb
4. For verbs ending in –y change –y to -i and add -ed
5. Present Participle: add -ing to end of verb
6. For verbs ending in –e remove –e before adding –ing.

This rule excludes verbs ending in –ee. Verbs ending in –ee follow normal convention of adding –ing to the end.

1. Third Person: add -s or -es to the end of verb
2. For verbs ending in –y change –y to -i and add -es

NOTE: Irregular verbs do not follow the rules for past and past participle conjugation.

How to deal with Irregular Verbs

Verbs are considered to be irregular when their past tense and past participle forms are different from one another and those forms are not formed by adding -ed, -d, or -t to the base form. Here are a few irregular verbs.

Verb	Past	Past participle
arise	arose	arisen
begin	began	begun
catch	caught	caught
do	did	done
fall	fell	fallen
go	went	gone
hide	hid	hidden
lay	laid	laid
lie	lay	lain

There are great resources to learn more about irregular verbs online. One of them is here: http://speakspeak.com/resources/vocabulary-general-english/english-irregular-verbs 

The next step to writing advanced definitions is to add semantic relationships to the definition.

---

Step 5 — Add Semantic Relationships to the Definition

Once you are finished with your definition you’ll need to place the new term into context with other terms. It allows your readers to see how terms interact with each other and  allows Natural Language Processing Engines to relate terms together. It is the core of pattern-matching to harmonize regulatory structures to each other.

Basic semantic relationships

The following basic relationships have been taken from the Simple Knowledge Organization System’s (SKOS) Mapping Vocabulary Specification[1], as shown below.

They offer the ability to distinguish subtle relationships between two terms. As stated in the specification:  

“Many knowledge organization systems, such as thesauri, taxonomies, classification schemes, and subject heading systems, share a similar structure, and are used in similar applications. SKOS captures much of this similarity and makes it explicit, to enable data and technology sharing across diverse applications.”

has-exact-match

If two concepts are an exact match, then the set of resources properly indexed against the first concept is identical to the set of resources properly indexed against the second. Therefore, the two concepts may be interchanged in queries and subject-based indexes. 

(Is inverse with itself.)

has-broad-match

If “concept A has-broad-match concept B,” then the set of resources properly indexed against concept A is a subset of the set of resources properly indexed against concept B. 

(Is inverse of has-narrow-match.)

has-narrow-match

If “concept A has-narrow-match concept B,” then the set of resources properly indexed against concept A is a superset of the set of resources properly indexed against concept B. 

(Is inverse of has-broad-match.)

has-major-match

If “concept A has-minor-match concept B,” then the set of resources properly indexed against concept A shares less than 50% but greater than 0 of its members with the set of resources properly indexed against concept B. 

(No inverse relation can be inferred.)

has-minor-match

If “concept A has-minor-match concept B,” then the set of resources properly indexed against concept A shares less than 50% but greater than 0 of its members with the set of resources properly indexed against concept B. 

(No inverse relation can be inferred.)

The limitations with basic semantic relationships based off the SKOS model

The problem in the SKOS model is relationships are limited to a single term or a single phrase. This model is great if you want to know that draft or chart is the same as map or not as broad as interpret. Basically, you are limited to three categories for practical purposes; broader, same, and narrower as shown in the diagram below.

What the SKOS and basic semantic relationship model doesn’t tell you is why interpret is a broader concept, or why scale is a narrower concept. What they don’t show are the linguistic relationships between the terms. 

To extend the relationships past broader, same, and narrower, you’ll need a more advanced semantic relationship system. It should consider real-world relationships such as:

• One concept being a category for another concept.
• One concept enforcing another concept.
• One concept including another concept as a part of it (versus the parent being a category). 

The illustration that follows re-examines the semantic relationships of the term map, shown above, using a more advanced set of semantic relationships. These relationships provide a much more robust understanding of connecting terms than a simple broader, same as, and narrower model can provide. 

Advanced semantic relationships extend the model by adding linguistic and conceptual connections to each relationship.

Advanced Semantic Mappings

There are many more relationships you’ll need to put into place if you want to provide greater context for your readers or Natural Language Processing Engine. Here are a few more of the relationships you’ll need.

Synonyms and Antonyms instead of has-exact-match

Synonyms are broader than exact matches, as they extend the relationship to facts or states of having correlation, interrelation, materiality, conformity, and pertinence between concept A and concept B. 

Antonyms then have enough variability, incongruence, and disassociation to be their opposite. The antonym is the inverse of the synonym and vice versa.

What is a metonymy?

Included in the type of synonyms is metonymy, the semantic relationship that exists between two words (or a word and an expression) in which one of the words is metaphorically used in place of the other word (or expression) in particular contexts to convey the same meaning. Included in the category of antonyms are complementary pairs, gradable pairs, and relational opposites[2].

What are complementary pairs?

Complementary pairs are antonyms in which the presence of one quality or state signifies the absence of the other and vice versa. A couple of samples are single/ married, not pregnant/pregnant. There are no intermediate states in complementary pairs.

What are gradable pairs?

Gradable pairs are antonyms which allow for a natural, gradual transition between two poles. A couple of examples are good/bad, hot/cold. It is possible to be a little cold or very cold, etc.

What are relational opposites?

Relational opposites are antonyms that share the same semantic features, but with the focus, or direction reversed. A few examples are tied/untied, buy/sell, give/receive, teacher/pupil, father/son, and open/refrain from opening.

Are there non-standard forms of has-exact-match?

A spigot and a faucet are two defined words that are exact matches, or synonyms, of each other. That’s an easy rule to implement. However, language is messy, and the uses of language within compliance documents are even messier. That’s why you must have advanced rules that go beyond synonyms for use cases (such as a personal data request being called a request for personal data, an information request from the data controller, or even a request for information on the processing of personal data). 

To handle these types of use cases you must have a semantic rule that says “if the definition of a term-of-art matches the definition of a previously accepted dictionary term, the term-of-art should be considered an exact match and therefore be labeled a non-standard representation of the accepted term”.

Replacing the broad and narrow matches with more specific categorization

The major and minor relationships described in the SKOS model are limited to linguistic parents and their children (or half-children as a minor match might be thought of). However, there are many relationships that are more specific that can and should be applied, especially when working with named entities and leveraging a Natural Language Processor’s named entity recognition engine. 

By replacing the simple broader and narrower matches with more specific categorization, you can achieve structures like those employed by the Compliance Dictionary, as shown below.

Relationship	Description	Examples
Linguistic Parent	Terms that are linguistically broader than the focus term, including origins of terms.	Term– Senior Systems Analyst
Linguistic Parent – systems analyst, senior
Linguistic Child	Terms that are linguistically narrower than the focus term, including derivatives. This is the inverse of Linguistic Parent.	Term — systems analyst
Linguistic Child — Senior Systems Analyst
Category For	A term of which the focus term is a kind of.	Term – tablet
Category For – portable electronic device
Type of	Terms that are kinds or examples of the focus term. This is the inverse of Category For.	Term – portable electronic device
Type of – laptop
Includes	Terms the focus term is an element of. It is the same as hyponymy.	Term – Personally Identifiable Information
Includes – mailing address, individual’s Social Security Number
Part of	Terms whose definitions are an element of the focus term. This is the inverse of Includes	Term – Personally Identifiable Information
Part of – privacy-related information
Used to Create	A term that is a template for or used to create the focus term.	Term – UCF Mapper software
Used to Create – Authority Document mapping
Is Created by	A term that comes from or is generated by the focus term. This is the inverse of Used to Create.	Term – system audit report
Is Created by – Secure Configuration Management Tool
Is Referenced by	A term that mentions or references the focus term.	Term – evidence
Is Referenced by – probable cause
References	A term that the focus term mentions or cites. This is the inverse of Is Referenced by.	Term – evidence
References – business exception rule
Used to Enforce	A term that uses the focus term to happen or cause compliance.	Term – configuration rule
Used to Enforce– system configuration
Is Enforced by	A term that uses the focus term to happen or cause compliance. This is the inverse of Used to Enforce.	Term – PCI-DSS
Is Enforced by – payment brand
Used to Prevent	A term that prevents the focus term.	Term – sanctions
Used to Prevent-– unauthorized data processing
Is Prevented by	A term that is prevented by the focus term. This is the inverse of Used to Prevent	Term – stealing
Is Prevented by– armed guard

Questions for analyzing the relationships of your terms

As of this writing, there isn’t a computer system that will automatically analyze terms, even in their context within a document, and determine what the relationships should be. At best, they are running between 40-45% accuracy[3]. This means you’ll want to manually ask yourself the questions, which isn’t really that hard[4]. 

Here’s our cheat sheet for you:

Relation Type	Questions
Synonyms	Have you seen this term spelled differently?
	Have you seen this term written completely differently (Personally Identifiable Information/individual’s non-public data)?
	Is this a metaphor for another term?
	Are there metaphors for this term?
Antonyms	Are there any qualities of this term that signify the absence of qualities of another term (single/married)?
	Could this term be graded on a spectrum (hot/cold)?
	Is there an opposite relationship of this term (tied/untied)?
Category of	What terms fall under this category?
Type of	Are there any other examples of this term?
Includes	What does this term include?
Part of	Is this term a part of a greater whole?
References	Does this term refer to other terms?
	Is this term referenced by other terms?

By creating semantic relationships to your definitions, the reader will be able to understand how the term works with other terms.

Step 6 – Reviewing Your Definitions

The final step is reading your definition and making sure that it agrees with the word and the sense you are trying to define. Testing your definition on the format we wrote earlier. 

In math, the substitution principle refers to the useful practice of replacing instances of a variable with a different variable. In definitions, it should be possible to replace a word in a definition by that word’s own definition without obtaining an unsatisfactory result[1]. 

For instance, if we were to use the substitution principle to examine covered entity, we would take the simple definition below:

Term	Definition
covered entity	Healthcare providers who transmit health information.

and replace key terms, such as healthcare provider, transmit, and health information.

Term

Definition

covered entity

Healthcare providers [individuals and organizations that provide healthcare services] who transmit [to send or cause something to pass on from one place or person to another] health information [Any information, including demographic information collected from an individual, that: (1) is created or received by a health care provider, health plan, employer, or health care clearinghouse; and (2) relates to the past, present, or future physical or mental health or condition of an individual; the provision of health care to an individual; or the past, present, or future payment for the provision of health care to an individual; and (i) that identifies the individual; or (ii) with respect to which there is a reasonable basis to believe the information can be used to identify the individual].

Verbose, but it works. The term doesn’t circle back on itself, begins with the category, and ends with the characteristics. 

The verdict? It’s a good definition.

How to Write Definitions for Specific Circumstances

We’ve established that in order to communicate clearly and effectively, we need to define our terms. Great. Got that out of the way. 

We’ve covered what a definition is, and generally how it is formatted with both category and differentiator content. Coolio (which means really great according to Dorian’s nieces and nephews). 

Now it’s time to look at how definitions are presented to people in writing. The scholars out there who talk about these things call all of these entries, collectively, terminological entries. And because we couldn’t think of anything easier to call them, that’s what we’ll call them too. 

We are going to divide terminological entries into three types, from the least formal to the most formal: 

1. conversational entries 
2. glossary entries 
3. custom dictionary entries. 

Why custom dictionary entries? Simple. We, collectively, aren’t the editors of Webster’s or the Oxford English Dictionary. But we can be editors of other dictionaries, custom dictionaries.

---

What are Conversational Entries?

Conversational definitions are those definitions wherein you write the definition into the normal discourse. A quick search of Wordnik (https://www.wordnik.com), the world’s largest online dictionary (as measured by numbers of words) run by Erin McKean, shows how they pick up and enter definitions through conversational entries.

The term in question is deepfake. It was picked up by Wordnik and reported in their Word Buzz Wednesday blog entry, taken from the New York Times20. As you can see in the illustration below, the term deepfake was bracketed with quotes and then the definition immediately follows.

Through what we see here, conversational definitions have two parts; the term and the definition, without formally introducing either one, and without any cataloging of the terms.

To write conversational entries, follow steps 1 through 3 of how to write definitions.

---

What are Snippet Entries?

Google takes conversational entries one step farther. These are fantastic if you want to drive a point home to the search universe as our team at Unified Compliance has done with the answer to “what is Unified Compliance”. 

When you search in Google with the phrase “what is/are XXX”, Google looks for either formal dictionary definitions of the term (first) and then if it can’t find one, will search for the most authoritative snippet of the term it can find. It then shows a search result in a special featured snippet block at the top of the search results page. This featured snippet block includes a summary of the answer, extracted from a webpage, plus a link to the page, the page title, and URL – as shown in the illustration below.

How do those get there? 

When Google recognizes that a query asks a question, it programmatically detects pages that answer the user’s question, and displays a top result as a featured snippet in the search results16. 

Can you mark a page as a featured snippet so that Google can find it easier? 

Sorry, Google programmatically determines that a page contains a likely answer to the user’s question, and displays the result as a featured snippet. You can’t code your way into owning definitions. You can, however, be the authoritative source for those definitions if you write your snippet as a definition!

Here’s how the Unified Compliance team did it. 

We wrote a page that we specifically designed to be a definition page for the term Unified Compliance. We wrote above the definition “What is Unified Compliance?”, thus asking the question. We then answered the question in the form of a conversational definition. We supplied the term first, “Unified Compliance”, followed by is (which acts as the separator between the term and the definition), and then followed that with the definition itself.

Like all good definitions, we began with the category into which the term fit, followed by the differentiators for the term. We even put bullet points in front of each differentiator for emphasis. The illustration above shows the page with the term and the definition called out.

To write snippet entries, follow steps 1 through 3 of how to write definitions.

How to Automate Glossary Creation

There is a new methodology for technical authors who do not want to equivocate about what they meant when writing whatever technical document it is they are writing. 

The Unified Compliance team has developed a verb and noun tagging and definition selection tool, shown below. The process is simple. When writing, the author tags the verbs and nouns they want to select definitions for, for that instance (knowing that terms such as report can mean many things, even within the same sentence).

Once the term has been tagged as either a verb or a noun, the system displays all of the definitions in the dictionary for that verb or that noun. Because the system is tied to an AI-based Natural Language Processing Engine, the system will automatically suggest the definition most used in the context of the sentence presented for tagging and matching. 

Once the terms have been tagged and the definitions selected, the tagging is hidden to readers but exposed to computer systems. This can generate pop-ups showing the definition for the term as it was tagged by the author. Or, as is the case with each document the Unified Compliance team manages, the system can automatically create a glossary of verbs and nouns for the document in question. 

This does, by the way, sometimes produce humorous results. One of our clients used the system to create a document written by multiple authors. The same term, only used six times in the document, had three different definitions selected. That’s because the different authors selected different definitions. 

Since that point, we’ve changed the software so that once a definition has been selected in the document, it is a bit more insistent that the same definition be used in the same context. This is a great tool for technical documents, regulatory documents, etc. in that there is no equivocation about what the author meant for any verb or noun the author wishes to select a definition for. 

Each word is tagged. Each definition is assigned. No doubt about what was meant. And the tagging and definitions follow the electronic format of that document forever. 

For more information on using this tool, please contact the Unified Compliance team.

What are Dictionary Entries?

Dictionary entries have grown in complexity over the past several years due to the restraint of physical printing being removed. Originally, as John Simpson pointed out several times in The Word Detective22, definitions had to be as concise as possible, owing to the need to conserve printed space. 

Electronic and online dictionaries don’t have such a restriction. Computer storage space, even on mobile phones, has grown exponentially year after year. The only restrictions on space now are those of the screen on which the dictionary is being presented.

Dictionaries will always have the first three categories of content, just like glossaries. However, given that electronic dictionaries are no longer constrained by printed size, many will have additional content that includes the various types of definitions.

1. Term or lemma – This is the term that will be defined. Lemma is the fancy word lexicographers give the term. Dictionaries always list their terms following strict capitalization rules.
2. Pronunciation helpers – Some dictionaries will have a small speaker () next to the term’s entry. When pressed, the term will be spoken out loud to assist the reader in understanding how to vocalize the term. Other dictionaries will have a syllable breakdown of the term entry, such as the breakdown for dictionary [dik-shuh-ner-ee]. This was the original pronunciation helper.
3. Preferred, nonstandard, and alternate spelling variants – Not many dictionaries, as of yet, contain these categories of data. Preferred terms are those terms normally found within a manual of style. The manual of style will list certain terms to use instead of other, like, terms. Nonstandard variants have entered the dictionary world as a part of analyzing various sets of corpora (the documents you are using and drawing terms from) and determining that the writers are using differing terms with the same definitions. The nonstandard variants are those outlying term uses that get added to dictionaries to let the Natural Language Processing engines know that personal data and individual’s information are the same thing. Alternate spelling variants are those versions where the US spells organization with a “z” and the UK spells organization with an “s”.
4. Acronym – Some dictionaries will place the acronym on a line below the term entry. Others will simply follow the term entry with the acronym in parentheses.
5. Designator and Definition – Dictionary definitions are more stringent than glossary definitions. Dictionary definitions will always begin with the definition’s designator. A designator is needed because some terms have multiple definitions, such as the term report (it has multiple definitions for both noun and verb). All dictionaries will list whether the definition that follows is a noun, pronoun, adjective, determiner, verb, adverb, preposition, conjunction, or interjection. Custom dictionaries will take this concept farther and will list whether the definition fits any specific type of named entity (we cover those later).
6. Attribution – Many online dictionaries, such as Wordnik and Compliance Dictionary will include definitions from multiple sources. When including definitions from multiple sources, these dictionaries will include the source’s attribution along with the definition.
7. Related forms – Any electronic dictionary that is built with the intention of working with Natural Language Processing Engines will also include all of the other forms that the term can take. The most common being plurals and possessives for nouns and all of the various verb tenses.
8. Relationships – Most dictionaries will list each term’s synonyms and antonyms. Dictionaries that also blend in a thesaurus will add additional terms related to the primary term. As of this writing, only Compliance Dictionary lists advanced semantic relationships such as category of, part of, used to enforce, references, manages, used to create, etc. These advanced semantic relationships are necessary for Natural Language Processing engines’ understanding of named entity relationships of terms.
9. Examples of use – Examples of use are wonderful. And with modern “document scraping” software, once a term has been identified, examples can be found in the dictionary’s corpus and brought to the forefront.
10. Reverse lookup – These are terms that the scraping engine of the dictionary has found that use the primary term in their definition.
11. Etymology – Some dictionaries will list the term’s origin, showing which parts of the term originated when and where, and how the term has evolved.
12. Visuals – Some of the newer online dictionaries, like Wordnik, will also have pictures and illustrations of the term listed with the definitions. They say a picture is worth a thousand words…

Not every dictionary will have every item. Wordnik, for example, has most of these items, but doesn’t have the named entity recognition designators, or the advanced semantic relationships that go with them. ComplianceDictionary doesn’t have the reverse lookup, etymology, or visuals.

To write custom dictionary entries, follow steps 1 through 6 of how to write definitions.

Get the Definitions Book

Although
the borderline between various linguistic units is not always sharp
and clear, we shall try to define every new term on its first
appearance at once simply and unambiguously, if not always very
rigorously. The approximate definition of the term word
has already been given in the opening page of the book.

The
important point to remember about
definitions
is that they should indicate the most essential characteristic
features of the notion expressed by the term under discussion, the
features by which this notion is distinguished from other similar
notions. For instance, in defining the word one must distinguish it
from other linguistic units, such as the phoneme, the morpheme, or
the word-group. In contrast with a definition, a description
aims at enumerating all the essential features of a notion.

To
make things easier we shall begin by a preliminary description,
illustrating it with some examples.

The
word
may be described as the basic unit of language. Uniting meaning and
form, it is composed of one or more morphemes, each consisting of one
or more spoken sounds or their written representation. Morphemes as
we have already said are also meaningful units but they cannot be
used independently, they are always parts of words whereas words can
be used as a complete utterance (e. g. Listen!).
The
combinations of morphemes within words are subject to certain linking
conditions. When a derivational affix is added a new word is formed,
thus, listen
and
listener
are
different words. In fulfilling different grammatical functions words
may take functional affixes: listen
and
listened
are
different forms of the same word. Different forms of the same word
can be also built analytically with the help of auxiliaries. E.g.:
The
world should listen then as I am listening now (Shelley).

When
used in sentences together with other words they are syntactically
organised. Their freedom of entering into syntactic constructions is
limited by many factors, rules and constraints (e. g.: They
told me this story but
not *They
spoke me this story).

The
definition of every basic notion is a very hard task: the definition
of a word is one of the most difficult in linguistics because the

27

simplest
word has many different aspects. It has a sound form because it is a
certain arrangement of phonemes; it has its morphological structure,
being also a certain arrangement of morphemes; when used in actual
speech, it may occur in different word forms, different syntactic
functions and signal various meanings. Being the central element of
any language system, the word is a sort of focus for the problems of
phonology, lexicology, syntax, morphology and also for some other
sciences that have to deal with language and speech, such as
philosophy and psychology, and probably quite a few other branches of
knowledge. All attempts to characterise the word are necessarily
specific for each domain of science and are therefore considered
one-sided by the representatives of all the other domains and
criticised for incompleteness. The variants of definitions were so
numerous that some authors (A. Rossetti, D.N. Shmelev) collecting
them produced works of impressive scope and bulk.

A
few examples will suffice to show that any definition is conditioned
by the aims and interests of its author.

Thomas
Hobbes (1588-1679),
one
of the great English philosophers, revealed a materialistic approach
to the problem of nomination when he wrote that words are not mere
sounds but names of matter. Three centuries later the great Russian
physiologist I.P. Pavlov (1849-1936)
examined
the word in connection with his studies of the second signal system,
and defined it as a universal signal that can substitute any other
signal from the environment in evoking a response in a human
organism. One of the latest developments of science and engineering
is machine translation. It also deals with words and requires a
rigorous definition for them. It runs as follows: a word is a
sequence of graphemes which can occur between spaces, or the
representation of such a sequence on morphemic level.

Within
the scope of linguistics the word has been defined syntactically,
semantically, phonologically and by combining various approaches.

It
has been syntactically defined for instance as “the minimum
sentence” by H. Sweet and much later by L. Bloomfield as “a
minimum free form”. This last definition, although structural in
orientation, may be said to be, to a certain degree, equivalent to
Sweet’s, as practically it amounts to the same thing: free forms
are later defined as “forms which occur as sentences”.

E.
Sapir takes into consideration the syntactic and semantic aspects
when he calls the word “one of the smallest completely satisfying
bits of isolated ‘meaning’, into which the sentence resolves
itself”. Sapir also points out one more, very important
characteristic of the word, its indivisibility:
“It cannot be cut into without a disturbance of meaning, one or two
other or both of the several parts remaining as a helpless waif on
our hands”. The essence of indivisibility will be clear from a
comparison of the article a
and
the prefix a-
in
a
lion and
alive.
A lion is
a word-group because we can separate its elements and insert other
words between them: a
living lion, a dead lion. Alive is
a word: it is indivisible, i.e. structurally impermeable: nothing can
be inserted between its elements. The morpheme a-
is
not free, is not a word. The

28

situation
becomes more complicated if we cannot be guided by solid spelling.’
“The Oxford English Dictionary», for instance, does not
include the
reciprocal pronouns each
other and
one
another under
separate headings, although
they should certainly be analysed as word-units, not as word-groups
since they have become indivisible: we now say with
each other and
with
one another instead
of the older forms one
with another or
each
with the other.¹

Altogether
is
one word according to its spelling, but how is one to treat all
right, which
is rather a similar combination?

When
discussing the internal cohesion of the word the English linguist
John Lyons points out that it should be discussed in terms of two
criteria “positional
mobility”
and
“un­interrupt­abili­ty”.
To illustrate the first he segments into morphemes the following
sentence:

the
—
boy
—
s
—
walk
—
ed
—
slow
—
ly
—
up
—
the
—
hill

The
sentence may be regarded as a sequence of ten morphemes, which occur
in a particular order relative to one another. There are several
possible changes in this order which yield an acceptable English
sentence:

slow
—
ly
—
the
—
boy
—
s
—
walk
—
ed
—
up
—
the
—
hill
up —
the
—
hill
—
slow
—
ly
—
walk
—
ed
—
the
—
boy
—
s

Yet
under all the permutations certain groups of morphemes behave as
‘blocks’ —
they
occur always together, and in the same order relative to one another.
There is no possibility of the sequence s
—
the
—
boy,
ly —
slow,
ed —
walk.
“One
of the characteristics of the word is that it tends to be internally
stable (in terms of the order of the component morphemes), but
positionally mobile (permutable with other words in the same
sentence)”.²

A
purely semantic treatment will be found in Stephen Ullmann’s
explanation: with him connected discourse, if analysed from the
semantic point of view, “will fall into a certain number of
meaningful segments which are ultimately composed of meaningful
units. These meaningful units are called words.»³

The
semantic-phonological approach may be illustrated by A.H.Gardiner’s
definition: “A word is an articulate sound-symbol in its aspect of
denoting something which is spoken about.»⁴

The
eminent French linguist A. Meillet (1866-1936)
combines
the semantic, phonological and grammatical criteria and advances a
formula which underlies many subsequent definitions, both abroad and
in our country, including the one given in the beginning of this
book: “A word is defined by the association of a particular meaning
with a

particular
group of sounds capable of a particular grammatical employment.»¹

This
definition does not permit us to distinguish words from phrases
because not only child,
but
a
pretty child as
well are combinations of a particular group of sounds with a
particular meaning capable of a particular grammatical employment.

We
can, nevertheless, accept this formula with some modifications,
adding that a word is the smallest significant unit of a given
language capable of functioning alone and characterised by positional
mobility
within
a sentence, morphological
uninterruptability
and semantic
integrity.²
All these criteria are necessary because they permit us to create a
basis for the oppositions between the word and the phrase, the word
and the phoneme, and the word and the morpheme: their common feature
is that they are all units of the language, their difference lies in
the fact that the phoneme is not significant, and a morpheme cannot
be used as a complete utterance.

Another
reason for this supplement is the widespread scepticism concerning
the subject. It has even become a debatable point whether a word is a
linguistic unit and not an arbitrary segment of speech. This opinion
is put forth by S. Potter, who writes that “unlike a phoneme or a
syllable, a word is not a linguistic unit at all.»³
He calls it a conventional and arbitrary segment of utterance, and
finally adopts the already mentioned
definition of L. Bloomfield. This position is, however, as
we have already mentioned, untenable, and in fact S. Potter himself
makes ample use of the word as a unit in his linguistic analysis.

The
weak point of all the above definitions is that they do not establish
the relationship between language and thought, which is formulated if
we treat the word as a dialectical unity of form and content, in
which the form is the spoken or written expression which calls up a
specific meaning, whereas the content is the meaning rendering the
emotion or the concept in the mind of the speaker which he intends to
convey to his listener.

Summing
up our review of different definitions, we come to the conclusion
that they are bound to be strongly dependent upon the line of
approach, the aim the scholar has in view. For a comprehensive word
theory, therefore, a description seems more appropriate than a
definition.

The
problem of creating a word theory based upon the materialistic
understanding of the relationship between word and thought on the one
hand, and language and society, on the other, has been one of the
most discussed for many years. The efforts of many eminent scholars
such as V.V. Vinogradov, A. I. Smirnitsky, O.S. Akhmanova, M.D.
Stepanova, A.A. Ufimtseva —
to
name but a few, resulted in throwing light

might be objected that such words as articles, conjunctions and a few

on this problem and achieved a
clear presentation of the word as a basic unit of the language. The
main points may now be summarised.

The
word
is the
fundamental
unit
of language.
It is a dialectical
unity
of form
and
content.
Its content or meaning is not identical to notion, but it may reflect
human notions, and in this sense may be considered as the form of
their existence. Concepts fixed in the meaning of words are formed as
generalised and approximately correct reflections of reality,
therefore in signifying them words reflect reality in their content.

The
acoustic aspect of the word serves to name objects of reality, not to
reflect them. In this sense the word may be regarded as a sign. This
sign, however, is not arbitrary but motivated by the whole process of
its development. That is to say, when a word first comes into
existence it is built out of the elements already available in the
language and according to the existing patterns.

Checklist

Below is a checklist for definitions. Use it to check your own writing, or get a peer (another student) to help you.

Item	OK?	Comment
The definition uses an appropriate verb (e.g. is…, may be defined as…).
The definition has an appropriate category (e.g. place, person).
The definition uses an appropriate wh-word (e.g. which for objects, who for people).
Other language for definitions is accurate.
If an extended definition is given (in a paragraph or whole essay), appropriate ways to structure the definition are used, e.g. etymology, exemplification, comparison, contrast, and so on.
