# What Are Prefixes in English?

Prefixes are small word parts that we add to the **beginning** of a base word. They change the meaning of the word, but they do not stand alone as full words. For example, if we add **un-** to **happy**, we get **unhappy**, which means “not happy.”

Prefixes are very common in English. They help us create new words quickly and understand meaning more easily. Once you learn some common prefixes, you can guess the meaning of many new words.

Here are a few examples:

– **un-** means “not”
– **unfair** = not fair
– **untidy** = not tidy

– **re-** means “again”
– **rewrite** = write again
– **redo** = do again

– **dis-** means “not” or “the opposite of”
– **disagree** = not agree
– **dislike** = not like

– **pre-** means “before”
– **preview** = see before
– **preheat** = heat before

– **mis-** means “wrongly” or “badly”
– **misunderstand** = understand wrongly
– **misplace** = place in the wrong spot

Prefixes can change the meaning of a word in important ways. For example, **do** and **redo** are related, but they do not mean the same thing. This is why prefixes are useful for both speaking and reading.

Learning prefixes can also help with spelling and vocabulary. If you know what a prefix means, you can often understand a word even if you have never seen it before.

## Conclusion

Prefixes are word parts added to the beginning of a word to change its meaning. They are an important part of English vocabulary. By learning common prefixes like **un-**, **re-**, **dis-**, **pre-**, and **mis-**, you can build your word knowledge and understand English better.
