The word prefix itself actually contains a prefix! The letters 'pre' is a prefix that means before or in front of. It is attached to the root word fix, which means attach.

Prefixes are always derivational, meaning once a prefix is used, it creates a new word with a different meaning from the base word.

When the prefix 'un ' is added to the base word 'happy ', it creates the new word 'unhappy'.

This new word (unhappy) has the opposite meaning of the base word (happy).

Using hyphens with prefixes

There are no fixed and complete rules regarding when you should and should not use a hyphen to separate a base word from its prefix. However, there are a few things you should be aware of to help you use prefixes and hyphens correctly.

Use a hyphen with a proper noun

You must use a hyphen if a prefix is attached to a proper noun.

Pre-World War I
Anti-American

Use a hyphen to avoid ambiguity

A hyphen should be used with a prefix in cases where it may lead to confusion over meaning or spelling. Confusion most commonly arises when the base word plus a prefix creates a word that already exists.

Re-cover vs Recover

Adding the prefix 're' to the word 'cover' creates a new word 'recover', which means to cover again.

However, this may cause confusion as the word recover already exists (a verb meaning to return to health).

Adding a hyphen makes it more apparent that 're' is a prefix.

Use a hyphen to avoid double vowels

If a prefix ends with the same vowel that the base word starts with, use a hyphen to separate the two.

Re-enter
Ultra-argumentative

There may be exceptions to this rule with the vowel "o". For example, 'coordinate' is correct, but 'coowner' is incorrect. In such cases, using a spellchecker may prove to be helpful.

Use a hyphen with 'ex' and 'self'

Certain prefixes such as 'ex' and 'self' are always followed by a hyphen.

Ex-wife
self-control

Knowing how to use prefixes will make you more proficient in the language and improve your vocabulary. It will also allow you to convey information in a more concise and precise manner.
