Word formation
de English Grammar Today
There are four main kinds of word formation: prefixes, suffixes, conversion and compounds.

Prefixes

We add prefixes before the base or stem of a word.

examples
prefixes
monorail, monolingual
mono- means ‘one’
multipurpose, multicultural
multi- means ‘many’
post-war, postgraduate
post- means ‘after’
unusual, undemocratic
un- means ‘not’ or ‘opposite to’

Suffixes

We add suffixes after the base or stem of a word. The main purpose of a suffix is to show what class of word it is (e.g. noun or adjective).

examples
suffixes
terrorism, sexism
-ism and -dom are used to form nouns
employer, actor
-er and -or are used to form nouns to describe people who do things
widen, simplify
-en and -ify are used to form verbs
reasonable, unprofitable
-able is used to form adjectives
unhappily, naturally
-ly is a common suffix used to form adverbs
