What Are Suffixes?

A suffix is a letter or a group of letters added to the end of a word to change its meaning or to ensure it fits grammatically into a sentence.

Here is an example of a suffix that changes a word's meaning:
  • joy + ous = joyous
  • (Here, the suffix changes a noun into an adjective.)
Here is an example of a suffix that ensures a word fits grammartically in the sentence:
  • She runs to work.
  • (Here, the suffix makes the verb fit; i.e., "She run" would be wrong.)
A suffix is a type of affix. The other type of affix is prefix, which are added to the front of a word.
