What is a prefix?

Prefixes are a group of letters that change the meaning of a word when they are added to the start.

Most prefixes mean a similar thing when they're added to different words.

The prefix un- usually means not. For example:

  • unhappy
  • unlocked
  • unfair

The prefixes dis- and mis- usually have negative meanings. For example:

  • disagree
  • disobey
  • misbehave

The prefix re- usually means again or back. For example:

  • redo
  • reappear
  • redecorate

The prefix sub- usually means under. For example:

  • subheading
  • submarine
