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.)

If you want to work smarter, not harder, when learning English, look at English prefixes.
Prefixes are letters that go at the beginning of words and change their meanings—learn some prefixes and you can learn hundreds of new words easily!
Think about the prefix un-, which means “not” and appears in words like unhappy (not happy), unable (not able), unpopular (not popular) and unnatural (not natural).
English prefixes can help you add to your English vocabulary knowledge and communicate better in general.

What Is a Prefix in English?
In English, many words are made up of prefixes, root words and suffixes.
A root word is the base of a word. It’s a simple word with a clear meaning that can be used alone or with the addition of prefixes and suffixes.
Prefixes are combinations of letters that go before a root word to change its meaning.
Suffixes are combinations of letters that go after a root word to change its meaning.
Technically, you can add many prefixes and many suffixes to make a super long English word. But for now, let’s just keep it simple!
When you’re learning vocabulary, it’s helpful to learn the definitions of common prefixes. In studying, you’ll find many new words that start with each prefix.
Knowing prefixes in English can also be helpful if you come across an unfamiliar word. You can break the word down to find the root word and the prefix. If you know what the prefix means, you’ll have a better idea of what the word means, too.
Now, let’s move on to the prefixes!
40 Common Prefixes in English to Help Build Your Vocabulary

How to Learn Prefixes in English
How do you practice English prefixes? Prefixes are hidden in hundreds of words that you hear every day, but how can you be smart about learning them?
Study a list
One idea is to study a list of common prefixes, like the list we shared above.
It can be helpful to memorize these prefixes and their definitions.
If you think of any other example words that use these prefixes, you can add them to the list to practice.
As you continue to study English, you can add any new prefixes you’ve learned to the list as well. Make sure to also write down example words so you can practice using the new prefix.
Find prefixes in your entertainment
Another way to study is to practice finding prefixes in English conversations, movies, books, magazines and videos. Write down any words with prefixes and try to guess what the word means before you use a dictionary.
When you’re watching movies, series or other types of videos, use subtitles so it’s easier to spot these little words. The movie scenes, trailers and comedy sketches on the FluentU language program have interactive subtitles that can give you more information on prefixes, like definitions and other videos that feature them.
Use online quizzes and resources
In order to see how much you’ve learned, it can be helpful to take a quiz about prefixes. There are many quizzes out there for you to use. We’ve listed a few here:
- ProProfs has a quiz that focuses on the definitions of prefixes. It has questions like: “Which prefix means “not”?” with multiple-choice answers. This is a great way to study prefixes on their own.
- English Media Lab focuses on words with prefixes instead of just the definitions. This quiz is a slightly higher level. It can help you see if you’ve improved and test your knowledge of prefixes and vocabulary in general.
- The prefixes and suffixes quiz on Quizizz is for advanced learners. This quiz is focused on grammar and asks questions about how to use prefixes. These are also multiple-choice questions, and you can create a free account to see the correct answers to each question.
Now that you’ve learned these 40 prefixes, it’s time to practice what you’ve learned. Practice using prefixes in conversation, and listen for when other English speakers use them.
In no time, you’ll realize that you can determine the meanings of hundreds of new vocabulary words. By just learning these prefixes, you’re well on your way to mastering the English language.

Post Prefix Spelling
Some of the words on this list are written with a hyphen (-) and some are not. Many of these words can be written either way. The spelling I included in this list comes from the way it is written in the Oxford Learner’s Dictionary or another source that I used. (Often Wikipedia.)
I have written them with correct spelling but there may be more than one way to spell each word. (Basically – don’t stress about it too much!)
You can see the results here for my grammar and spell-check software Grammarly. Postseason and post-season are both acceptable spellings BUT… post season, written as two words, is not.

I found a list online of 1000 words that begin with the prefix post. I went through this long list and tried to find the words starting with this prefix that are connected to common English words. The new word has a clear meaning of AFTER or behind.
I included some common words whose meaning is behind or after but they are not true prefix words. The word that comes after POST- is not a common word that is used by itself. See if you can tell which ones they are.
Next, I put these words in the category groups as an easy reference for you.
