Prefix Definitions

A prefix is a letter or a group of letters that attaches to the beginning of a word and helps to indicate or modify its meaning. An easy example would be the word ‘prefix’ itself! It begins with the prefix pre-, which means ‘before’.

It is quite important to understand what different prefixes mean as they can help to understand the meanings of any new vocabulary that you learn. However, you do need to be careful, as sometimes a prefix can have more than one meaning!

An example would be im-, this can mean ‘not’ or ‘into’.

YOUR QUESTIONS ANSWERED

What are the prefix words?

Prefixes are words that don’t mean anything on their own. They only serve to change the meaning of the word they are attached to. Prefixes, because of that, are not really words.

Prefixes are attached to the start of other words.

Example:

• DIS-

DISbelief, DISpleasure, DISconnect

DIS, by itself, does not mean anything. When it’s combined with another word it changes the meaning.

Some prefixed are words that have a meaning on their own, but they are short and can be attached to other words.

Words with the prefix for?

The prefix for is very old, and it comes from Scandinavian languages. It was adopted by the English language and has been used for ages. Usually, the prefix for is added to words when they are supposed to describe something that ends up being worse than it started.

Many words that have the prefix for are old, and are not used very commonly today.

Examples:

• Forbear, forbuy, forcut, fordo, forswearer, forgather, forhang, forlet, forlive, forset, forslow, forstop, fortear, fortread, forwarn, forwork, etc.

Other words are used in English regularly, and the prefix has been integrated into the word. In some words an E has been added between the suffix and the rest of the word. In other modern versions the prefix has remained the same

Examples:

• Forebode, forego, forefather, forbidden, forsake, foreshadow, foreskin, forsworn

Prefix Herbicide

Prefix herbicide is an American product that is manufactured in the US, and used to treat various types of grass. It is a selective herbicide and can be applied to different types of grassy terrain, as well as come crops. PREFIX is the name of manufacturer.

Are prefix allowed in scrabble?

Prefixes by themselves are not allowed in Scrabble. This means that just putting any prefix such as post-, pre-, neo-, eb-, or others, is not allowed.

However, you can use words that are built with prefixes. Only complete words are allowed in Scrabble. This means that you can use postmodernism, instead of just modernism.

Can prefix be a noun / verb / plural?

Prefixes as grammatical elements are not complete words. They cannot be any type of word except a prefix. Prefixes are used to change words and are always added to another type of words.

The only case when prefixes are complete words is when two or more words are hyphenated together. Some examples are jet-black, tar-runway, hot-blooded, and others. In this case, two full words are connected with a hyphen.

Prefix and Postfix

Prefix and postfix are terms used in programming and coding. They are connected to operators and operands. Each appears in a different situation, and achieves different results.

A prefix is an expression where the operator appears in the expression before the operands. This is then called a prefix expression.

A postfix appears in an expression when the operator appears in the expression after the operands. This is then called a postfix expression.

Prefix and postfix expressions are used in C++, Java, and C#.

A suffix is a letter or a group of letters that is usually attached to the end of a word to form a new word, as well as alter the way it functions grammatically.

Words with Suffixes

Depending on whether it is a noun, verb, adjective or adverb, a different suffix would be required. For example, the verb read can be altered to become the noun reader by adding the suffix ­-er. The same verb can also be turned into the adjective readable by adding the suffix –able.

It is just as important to understand the definitions of suffixes as prefixes, because they too help us to deduce the meanings of any new words that we learn. I have listed some of the most common suffixes below:

So as you can see, affixes can dramatically change the definitions of words. Knowing the various prefixes and suffixes along with their meanings can really help you to understand how words are used, and also how they should be spelled.

Although these groups of letters (affixes) are important and assist with forming words, they are not words in their own right and cannot stand alone in a sentence.

If they are printed or written alone, then they should have a hyphen before or after them to demonstrate that they are to be attached to other letters to form words (the way I have listed them in the above tables).

BANK ACCOUNT SUFFIX

What does Bank account Suffix mean?

Account numbers and card numbers are divided into sections. While the prefix denotes the bank issuing the card, the body is the account numbers, and the suffix is the account type.

The suffix is important because it lets the bank know which type of account is being used, and that way customers can’t access operations not approved for the type of account. The suffix is made up of two to three numbers.

Different numbers describe a different type of account. There are various types of accounts, and each has a unique number profile for a specific bank.

Examples:

• Cheque account – 00, Number 2 account – 02, Fixed account – 03, Savings account – 30, Credit card account – 40, Thrift club account – 50, Term deposit account – 81

👉 Combining Forms

When you are learning the different types of prefixes, it is important to remember that not every word containing these combinations is a prefix. Sometimes words have ‘combining forms’, which look very similar to prefixes but work differently!

Let me explain….

As you know, a prefix is a letter or a group of letters that appears at the beginning of words, but it can also be removed from the base word, and the word would still be a word without it, even if the meaning changes.

For example, non- means ‘not’ or ‘without’, this is used in words such as ‘nonsense’. The word ‘sense‘ can be separated from the prefix and it would still be a word on its own, even if the meaning is different.

So, combining forms act as prefixes but are different, because the remaining letters cannot be separated to form an independent word.

Here are some examples of prefixes that are also ‘combining forms’:

PREFIX	MEANING	EXAMPLE	COMBINING FORM	MEANING	EXAMPLE
com-, con-	with, alongside	comprise, connote	com-, con-	with, jointly	companion, comrade, community
contra-	against	contraindicate	contra-	against	contraceptive, contradict
de-	opposite	devalue	de-	down, away	descend
ex-	former	ex-husband	ex-	out	exhort
a-	not, without	amoral	a-, an-	not, without	apathy, anaemic
in-	not	inconvenient	in-	into	inebriate, indulge
homo-	same	homograph, homophone	homo-	same	homogeneous
magn-	great	magnate	magn-	great	magnificent, magnanimous, magnitude, magnify
para-	beside	paragraph, paramedic	para-	beside	paradox
sub-	under	submarine	sub-	under	substitute
trans-	across	transnational, transparent	trans-	through, across	transmit, transcend
tri-	three	triangle, tripod	tri-	three	triceps, triathlon

What is a prefix? — an introduction

On our parent page, we went over the term, affixation, which is the process of adding a prefix or suffix to a root word to change it. Now, we are going to focus solely on the prefix for this section.

Prefixes by definition are morphemes (the smallest possible unit with grammatical functionality — these are your atoms!) that are added onto the beginning of root words to alter their meaning.

For example, –dis is one of many such prefixes. –Dis has the sense of “opposite of” or “against”.

Let’s take a look at the prefix –dis, as an example, to see how many types of words can be made.

Verbs

Disagree.	I disagree with your proposal.
Disappear.	She just disappeared.
Disintegrate.	It seems the world is disintegrating.
Disapprove.	I disapprove of your behaviour.

Nouns

Disagreement.	I hate disagreements.
Disappearance.	There’s been a disappearance.
Disintegration.	We’re seeing a disintegration.
Disapproval.	There was disapproval from the passers-by.

Adjectives

Disagreed.	The disagreed price.
Disappeared.	A disappeared island.
Disintegrated.	It’s a disintegrated company.
Disapproving.	He received disapproving looks.

Sidenote

Note that most past participles “surprised”, “changed” etc., also function as adjectives. Moreover, gerund forms such as “surprising”, “changing” etc., also function as adjectives. This is just a small example of how many words you can create and utilise just by knowing one affix (in this case, it’s a suffix –ing).

The list of prefixes is long, and we’re not going to go over all of the prefixes in this course. Nevertheless, what we will do is teach you how to utilise different prefixes depending on what kind of word you want to use, i.e., an adverb, noun, adjective, verb etc.

By just knowing 1 prefix, you can create many new words

Let’s analyse how you can use the same prefix for the same word to create many more words.

To start, we will use a handful of popular prefixes that are primarily used for negation, that is, for making phrases negative, –il, –im, –in, –un and –ir.

—il: legal

Noun = illegality.	There is far too much illegality to what you’re saying.
Verb = illegalise (UK spelling) / illegalize (US spelling)	In some countries, they have illegalised smoking in bars.
Adverb = illegally.	You have been working illegally.
Adjective = illegal.	This is completely illegal.

—im: possible

Noun = impossibility	There are too many impossibilities for my liking I’m afraid.
Adverb = impossibly	Impossibly, he manages to climb the mountain.
Adjective = impossible	This is surely an impossible task.

—in: definite

Noun = Indefiniteness	There is just a lot of indefiniteness in this project.
Adverb = Indefinitely	We’ll be living here indefinitely.
Adjective = Indefinite	The subject is indefinite.

—un: forgive

Noun = unforgiveness and unforgiver	Leave your unforgiveness behind you. We are unforgivers.
Verb = unforgive	He unforgave me, unfortunately.
Adverb = unforgivingly	They unforgivingly stole everything.
Adjective = unforgivable	This crime is unforgivable.

 —ir: responsible

Noun = irresponsibility	Jack’s irresponsibility led us here.
Verb = irresponsibilise (UK spelling) / irresponsibilize (US spelling) (rare)	You’ve managed to irresponsiblise our duties, thanks (sarcastically).
Adverb = irresponsibly	Sometimes you seem to behave irresponsibly.
Adjective = irresponsible.	That’s an irresponsible excuse.

The prefixes that we have used are for negation usage, that is, to make words negative. Follow along, and we will focus on other prefixes and how to use them.

As you can see from the tables above, the prefixes do not normally change the category of a word, rather, this is the task of suffixes, that is, to alter part of speech. For instance, adjective to an adverb, or noun to a negative noun etc.

Which prefix do I use?

How do we know which prefix to use? Is there a rule for correct prefix utilisation, or affix utilisation in general? Unfortunately, there is no rule as to which affix goes where, however, once you know the intended purpose of each prefix (or suffix) it’s easy to add them.

Once you know, for example, the prefix –en means “cause to be” or “put into” you can then apply these prefixes to a plethora of verbs, thereby increasing your vocabulary and overall proficiency in English.

These are just a couple of examples, but let’s take a look.

Many common words such as able, slave, trust, rich, courage, dear, close, and circle can be turned into verbs just by using –en. (In this case, the prefix, –en does indeed change the category of the word).

As an example, let’s use the prefix –en to make verbs

Common words (adjectives and nouns)	Verb	Context
Able	Enable	You’ve enabled me to do anything that I want.
Slave	Enslave	Many were enslaved.
Trust	Entrust	I have entrusted upon you my throne.
Rich	Enrich	This experience will surely enrich you.
Courage	Encourage	Let’s encourage her so she can join in.
Dear	Endear	You have certainly endeared me to do my best.
Close	Enclose	We have enclosed something for you in the letter.
Circle	Encircle	You’ll need to encircle the town.

How to know which prefix to use if there’s more than one

But how can we know which prefix to use if there is, on occasion, more than one option?

Correct prefix utilisation is not easy, however, by knowing each prefix’s rule, your language learning experience shall be immediately improved.

The key to this lesson is showing you, the learner, the mechanics of prefix usage and how to apply prefixes to the words you use in English.

If you’ve already been learning English for some time, some prefixes (and suffixes) will just sound more natural to you than others, and generally, this means that the more natural-sounding prefix is usually the correct option.

We’re not saying you’ll select the correct prefix every single time based on this logic, but you will get most of them right. Let’s take a quick look.

Prefix rules — an example

Take for instance the prefix –sub which means “above” and “under”. Which other prefixes can you think of that have a similar meaning? Not many, well, maybe –un, but we use this prefix for negation and not for the above reasons.

Nevertheless, let’s go through some newly made words with the prefix –sub to see which is the best.

Let’s take the words, merge, marine, category, continent, way, contractor; what sounds more natural to you:

• Submerge or unmerge?
• Submarine or unmarine?
• Subcontractor or uncontractor?

I hope you said, submerge, submarine and subcontractor.

These options should sound like the best options for any English learner that has been submerged in the language for at least six months.

On the other hand, correct utilisation of prefixes is easier than correct utilisation of suffixes simply because there are more options when it comes to suffixes, but that is a topic for our next lesson on suffixes.

What kinds of words (noun, adjective etc.) can a prefix make?

All this talk about prefixes, but what kinds of words do prefixes make?

Generally, prefixes don’t determine the class of a word, i.e., a noun, verb, adjective, adverb etc., that’s the principal job for suffixes (suffixes will be discussed in the next lesson).

So, for a word to change the form, i.e., to a verb or to an adjective etc., a new suffix needs to be added.

Nevertheless, let’s take a look at a few words that are using the same prefix throughout all the different forms so that you can see how one word can change into different words whilst the prefix stays the same.

A very popular prefix –inter is used to mean “between”. We’ll take a look at some words in different forms.

Example word: change

Noun(s)	Meaning	Example
Interchangeability	Capable of being changed (in nominal form).	There is some serious interchangeability in times of financial crisis.
Interchange	The act of interchanging (in nominal form).	At our school we get to do interchanges between countries.
Verb	Meaning	Example
Interchange	The act of interchanging (in verbal form).	We have interchanged ideas and it feels amazing.
Adjective(s)	Meaning	Example
Interchangeable Interchanging	The act of interchanging (in adjectival form).	My trousers are interchangeable. An interchanging process.
Adverb	Meaning	Example
Interchangeably	The act of interchanging (in adverbial form).	We moved interchangeably on the dance floor.

The same prefix (-inter) was used to mean “between”, and it was used with different forms (nouns, a verb, adjectives, and an adverb).

The prefix per se didn’t alter the words (the suffixes altered the words), but this short example has shown that you can use the same prefix to make different types of words whilst using the same stem.

Ultimately, this makes your job easier, and eventually, your English will become much more concise and articulate.

There are a lot of words in English with prefixes of Latin, Greek, and Old English origin. In the course of time, prefixes in many words have lost their meanings, while many other prefixes still have more or less clear meanings.

A list of prefixes, with meanings and examples, is provided below. The list also includes some prepositions, postpositions (adverbial particles), and combining forms (e.g., auto, multi, pseudo, etc.) used as prefixes (i.e., at the beginning of the word) in the formation of a large number of compound words.

Russian translation of the words in the list is provided for the purpose of comparing the differences and similarities in the use of English and Russian prefixes. (Only one meaning is given in translation.)

The words in the list below are written according to American spelling norms. Some of these words may have two variants of spelling, with or without a hyphen after the prefix. (See Hyphen with Prefixes in the section Writing.)

Английские префиксы, со значениями и примерами

В английском языке очень много слов с префиксами латинского, греческого и древнеанглийского происхождения. С течением времени префиксы во многих словах утеряли свои значения, в то время как многие другие префиксы по-прежнему имеют более или менее ясные значения.

Список префиксов, со значениями и примерами, дан ниже. Список также включает некоторые предлоги, послелоги (наречные частицы) и присоединяемые формы (например, auto, multi, pseudo и др.), используемые как префиксы (т.е. в начале слова) в образовании большого количества сложных слов.

Русский перевод слов в списке дан с целью сравнить различия и сходства в употреблении английских префиксов и русских приставок. (Только одно значение дано в переводе.)

Слова в списке ниже написаны согласно американским нормам правописания. Некоторые из этих слов могут иметь два варианта написания, с дефисом или без дефиса после префикса. (См. Hyphen with Prefixes в разделе Writing.)
