Types of English Affixes: Derivational and Inflectional Prefixes and Suffixes

Types of English Affixes: Derivational and Inflectional Prefixes and Suffixes

An affix is a bound morpheme that attaches to the stem of a word to form either a new word or a new form of the same word.

The two types of affixes in English are prefixes and suffixes.

Affixes may be derivational or inflectional. Derivational affixes create new words. Inflectional affixes create new forms of the same word.


Derivational is an adjective that refers to the formation of a new word from another word through derivational affixes.

In English, both prefixes and suffixes are derivational.


Inflectional is an adjective that refers to the formation of a new form of the same word through inflectional affixes.

In English, only suffixes are inflectional.


A prefix is a bound morpheme that attaches to the beginning of the stem of a word to form either a new word or a new form of the same word.

Prefixes are types of affixes.

All prefixes in English are derivational, meaning the affixes create new words.
