How to know the meaning of a word in a sentence

How to Guess What a Word Means

Need to know what a new word means now? Did you know the English language has over 1,000,000 words? Yet the average adult learner has a vocabulary of only 40,000-50,000 words. With so many words out there, how can you learn them all? There are various strategies that you can learn which will help you to deduce what a word means. Yes, you could just look them up in an English dictionary; but, studies show that you most likely won’t remember the word after a while. However, by making your brain figure it out, a trail of understanding is left and you are more likely to remember the meaning, thus improving your vocabulary!

Perhaps you are taking a standardized test and are being asked about particular words. These strategies will help you immensely! We also provide some example sentences to help find the meaning of the word needed or of any individual words you need help with.

Context — If the word is used in a sentence, look at the other words and see if they give you clues to the word’s meaning. This may help to guess, at least, part of the word’s meaning.

EX. «‘Proximal’ refers to points on the body that are close to the torso, as opposed to ‘distal.

Given the context of the sentence, we can see the word «opposed» which means «to be opposite of.» If ‘proximal’ is opposite of ‘distal’ we can conclude that the word distal likely is used to refer to parts of the body that are far from the torso, like fingers. At this point, you can look in the dictionary to check our guess. You can also look at similar antonyms or synonyms for meaning of the new or unfamiliar words as well. While most English words act as idioms, the meaning of a word can be tricky if you are learning English or are learning more advanced words. Collocations can also help in the word meaning process by using context clues to find the correct answer or meaning to the word’s meaning.

STRUCTURE- Probably the most important skill when it comes to understanding words. The internal structure of words is called morphology. Morphology consists of morphemes—which are minimal units of meaning, rules for combining them into words, and rules for pronouncing the resulting words. For this article, we will keep it simple and go over a few key things.

Using your understanding of morphology helps you break down a word into smaller pieces so that you can guess what it means. For example, let’s use a nonsense word, say, POIB.

*What would POIB-able mean? (Capable of being POIBed)

*What is the word class of POIB-able? (Adjective)

*So, what is the word class of POIB? (Verb)

This exercise is to show how we can make some assumptions about the word we don’t know simply by how it is used in the sentence and what affixes are attached to it (affixes are a type of morpheme). This is how we can tell the word’s word class: noun, verb, adjective, adverb, etc.

MORPHEME- A morpheme may be a word or less than a word. (EX. nation, re-, -al). Morphemes cannot be broken down into smaller units.

TYPES OF MORPHEMES- Prefixes, Suffixes, Infixes, Plurals, Possessives, and base(root) words.

**Free morphemes are words that can stand on their own and have meaning.

For example, «nation» does not require a prefix or a suffix attached to it to make sense. It’s a word by itself.

**Bound Morphemes cannot stand on their own and must be attached to another morpheme to create a word.

For example, «dental»= dent + al. Together they make a word, but neither «dent» nor «al» are words themselves. All affixes are boundmorphemes. Some base (root) words are bound.

AFFIXES — anything that is added to a base (root) word. Determine how the affix affects the base (root) word it is attached to.

*Examples of affixes that change word class (i.e. from a verb to adverb)-er, -ly, -al, -y, -ish

*Examples of affixes that add to meaning of the base (root) word.anti-, omni-, re-, -s, -ed, dis-

***There are only about 75 prefixes in English. There are less suffixes. Memorize them.

Now that you understand what a morpheme is. The next step is to take your word and try to break it down into morphemes. Let’s use the word «predetermined» as our example. Predetermined= pre + determine + ed

We may know that the base (root) word ‘determine’ means to decide; the prefix ‘pre’ means before, and the suffix ‘ed’ is used to mean the past tense of a verb.

Therefore, «predetermined» would mean to have already decided the outcome of something before it happened.

Another example: quadruped = quadru + ped, meaning four feet. Both «quad» and «ped» are bound morphemes that must be attached to another morpheme to create a word.

KNOW YOUR ROOTS — Sometimes after you break down your word, you still may not know the meaning because you don’t know what the base (root) word means. Let’s say that you didn’t know the above root word «ped» was a Greek origin word meaning ‘feet.’ How could you try to guess what it meant?

*Think of other words you know that have «ped» in them?

• What do these words have in common?

EX. pedestal, pedal, pedestrian, millipede

You guessed it, FEET!

With the strategies above you can usually guess what a word means. If you are taking a test, use what you’ve assumed about the word to help with the process of elimination. Looking at word lists can also help in the meaning process.

Happy vocabulary building!

There are a few things that can help you estimate the meaning of a word, even if you have never read or heard it before. If you are taking a standardized test and will be asked about particular words, if you are learning English or if you just want to expand your vocabulary these strategies will help you immensely. Use the words around the unfamiliar word to help you guess the meaning, or use your knowledge of suffixes and prefixes to help you estimate the meaning of the new word. By figuring out the meaning of a new word, you may be more likely to remember the meaning and the new word.

Sound out the unfamiliar word if you are reading it. A word that seems unfamiliar at first may be a word you already know once you hear it out loud.

Look at the other words in the sentence to see if they give you clues to the new word’s meaning. This is called «context,» and may help you guess at part of the word’s meaning. For example, «proximal» refers to points on the body that are close to the torso, as opposed to «distal.» Here you can see the words «opposed to» which mean «to be opposite.» If «proximal» is the opposite of «distal,» you can conclude that the word «distal» likely is used to refer to parts of the body that are far from the torso such as fingers.

Break the new word down into its smallest parts. These small parts are called «morphemes.» A morpheme may be a word or less than a word. For example, «nation,» «re-,» and «-al» are all morphemes. Morphemes cannot be broken down into smaller units. There are many types of morphemes including prefixes, suffixes and root words. Free morphemes are words that can stand on their own and still have meaning. For example, «nation» does not require a prefix or a suffix attached to it to make sense. It’s a word by itself. Bound morphemes cannot stand on their own and must be attached to another morpheme to create a word. For example, the «s» in the word «dogs» is a bound morpheme. Without the word «dog,» the «s» has no meaning.

Learn about the structure of English words. English words have their roots in Greek, Latin and Germanic languages. Sometimes after you break down your word, you still may not know the meaning because you don’t know what the root word means. For example, let’s say you read the word «millipede.» There are two roots in this word. The root word «ped» is a word of Latin origin meaning «feet.» You can guess what it means by thinking of other words that have the root «ped.» You might think of «pedestal,» «pedal» and «pedestrian.» From these words, you can guess that your new word has something to do with feet. You might guess that «mille» has something to do with «million,» and you’d be on the right track. It means «thousand,» but in this word just means «many.» So, a millipede is something with many legs. If you check your dictionary, you will find that a millipede is an insect with many legs. This means you guessed most of the meaning of the word simply from looking at the root words.

Learn English affixes. Anything that is added to the beginning or end of a root word is an affix. Affixes include suffixes, prefixes and pluralization. Knowing the affixes can help you determine how the affix affects the root word it is attached to. Some affixes change the word class, for example from a verb to adverb. These include affixes like «-er,» «-ly» and «-ish.» Some affixes add to the meaning of the root word. These include affixes like «anti-,» «re-» and «-ed.» While it may take some time to learn them all, by breaking words down into morphemes you will begin to recognize which are affixes and which are roots. For example, let’s use the word «predetermined» as an example. «Predetermined» is made up of the prefix «pre,» the root «determine» and the suffix «ed.» You may know that the root word «determine» means to decide, the prefix «pre» means before and the suffix «ed» is used to mean the past tense of a verb. Therefore, «predetermined» means to have already decided the outcome of something before it happened.

Every teacher wonders how to teach a word to students, so that it stays with them and they can actually use it in the context in an appropriate form. Have your students ever struggled with knowing what part of the speech the word is (knowing nothing about terminologies and word relations) and thus using it in the wrong way? What if we start to teach learners of foriegn languages the basic relations between words instead of torturing them to memorize just the usage of the word in specific contexts?

Let’s firstly try to recall what semantic relations between words are. Semantic relations are the associations that exist between the meanings of words (semantic relationships at word level), between the meanings of phrases, or between the meanings of sentences (semantic relationships at phrase or sentence level). Let’s look at each of them separately.

Word Level

At word level we differentiate between semantic relations:

• Synonyms — words that have the same (or nearly the same) meaning and belong to the same part of speech, but are spelled differently. E.g. big-large, small-tiny, to begin — to start, etc. Of course, here we need to mention that no 2 words can have the exact same meaning. There are differences in shades of meaning, exaggerated, diminutive nature, etc. 
• Antonyms — semantic relationship that exists between two (or more) words that have opposite meanings. These words belong to the same grammatical category (both are nouns, adjectives, verbs, etc.). They share almost all their semantic features except one. (Fromkin & Rodman, 1998) E.g.
  
• Homonyms — the relationship that exists between two (or more) words which belong to the same grammatical category, have the same spelling, may or may not have the same pronunciation, but have different meanings and origins. E.g. to lie (= to rest) and to lie (= not to tell the truth); When used in a context, they can be misunderstood especially if the person knows only one meaning of the word.

Other semantic relations include hyponymy, polysemy and metonymy which you might want to look into when teaching/learning English as a foreign language.

At Phrase and Sentence Level

Here we are talking about paraphrases, collocations, ambiguity, etc.

• Paraphrase — the expression of the meaning of a word, phrase or sentence using other words, phrases or sentences which have (almost) the same meaning. Here we need to differentiate between lexical and structural paraphrase. E.g.

  Lexical — I am tired = I am exhausted.
  Structural — He gave the book to me = He gave me the book.

• Ambiguity — functionality of having two or more distinct meanings or interpretations. You can read more about its types here.
• Collocations — combinations of two or more words that often occur together in speech and writing. Among the possible combinations are verbs + nouns, adjectives + nouns, adverbs + adjectives, etc. Idiomatic phrases can also sometimes be considered as collocations. E.g. ‘bear with me’, ‘round and about’, ‘salt and pepper’, etc.

So, what does it mean to know a word? 
Knowing a word means knowing all of its semantic relations and usages.

Why is it useful? 
It helps to understand the flow of the language, its possibilities, occurrences, etc.better.

Should it be taught to EFL learners? 
Maybe not in that many details and terminology, but definitely yes if you want your learners to study the language in depth, not just superficially.

How should it be taught?
Not as a separate phenomenon, but together with introducing a new word/phrase, so that students have a chance to create associations and base their understanding on real examples. You can give semantic relations and usages, ask students to look up in the dictionary, brainstorm ideas in pairs and so on.  

Let us know what you do to help your students learn the semantic relations between the words and whether it helps.

A technology that strives to understand human communication must be able to understand meaning in language. In this post, we take a deeper look at a core component of our expert.ai technology, the semantic disambiguator, and how it determines word meaning and sentence meaning via disambiguation.

To start, let’s clarify our definitions of words and sentences from a linguistic point of view.

Word Meaning and Sentence Meaning in Semantics

Semantics is the study of the meaning of words, phrases, sentences and text. This can be broken down into subcategories such as formal semantics (logical aspects of meaning), conceptual semantics (cognitive structure of meaning) and today’s focus of lexical semantics (word and phrase meaning).

A “word” is a string of characters that can have different meanings (jaguar: car or animal?; driver: one who drives a vehicle or the part of a computer?; rows, the plural noun or the third singular person of the verb to row?). A “sentence” is a group of words that express a complete thought. To fully capture the meaning of a sentence, we need to understand how words relate to other words.

Going Back to School

To understand word meaning and sentence meaning, our semantic disambiguator engine must be able to automatically resolve ambiguities with any word in a text.

Let’s consider this sentence:

John Smith is accused of the murders of two police officers.

To understand the word meaning and sentence meaning in any phrase, the disambiguator performs four consecutive phases of analysis:

Lexical Analysis

During this phase, the stream of text is broken up into meaningful elements called tokens. The sequence of “atomic” elements resulting from this process will be further elaborated in the next phase of analysis.

• John > human proper noun
• Smith > human proper noun
• is > verb
• accused > noun
• of > preposition
• the > article

Grammatical Analysis

During this phase, each token in the text is assigned a part of speech. The semantic disambiguator can recognize any inflected forms and conjugations as well as identify nouns, proper nouns and so on.

Starting from a mere sequence of tokens, what results from this elaboration is a sequence of elements. Some of them have been grouped to form collocations (e.g., police officer) and every token or group of tokens is represented by a block that identifies its part of speech.

• John Smith > human proper noun
• is accused > predicate nominal

Syntactical Analysis

During this phase, the disambiguator operates several word grouping operations on different levels to reproduce the way that words are linked to one another to form sentences. Sentences are further analyzed to attribute a logical role to each phrase (subject, predicate, object, verb, complement, etc.) and identify relationships between them and other complements whenever possible. In our example, the sentence is made of a single independent clause, where John Smith is recognized as subject of the sentence.

• John Smith > subject
• is accused > nominal predicate

Semantic Analysis

During the last and most complex phase, the tokens recognized during grammatical analysis are associated with a specific meaning. Though each token can be associated to several concepts, the choice is made by considering the base form of each token with respect to its part of speech, the grammatical and syntactical characteristics of the token, the position of the token in the sentence and its relation to the syntactical elements surrounding it.

Like the human brain, the disambiguator eliminates all candidate terms for each token except one, which will be definitively assigned to the token. When it comes across an unknown element in a text (e.g., human proper names), it tries to infer word meaning and sentence meaning by considering the context in which each token appears to determine its meaning.

• Is accused > to accuse > to blame
• police officer > policeman, police woman, law enforcement officer
