Prefix and Suffix Types

We use a prefix at the beginning of the word to change the meaning and a suffix at the end of a word when we often use them to change the type of word.  Understanding when to use prefixes and suffixes correctly are an important part of doing the word formation exercise , which is Part 3 in the Use of English exam.

We will look at a number of prefixes here.

Negative Forms

Prefixes generally come in two groups

  • Prefixes that are negative
  • Prefixes where the meaning makes other changes to the meaning of the word
