• Added at the end of a base word.
• Change the word’s grammatical role.
• Form nouns, verbs, adjectives, and adverbs.

Types of Suffixes in English

Suffixes fall into two main types: inflectional and derivational. Inflectional suffixes change a word’s form without altering its meaning, while derivational suffixes create new words entirely. Recognizing these types gives learners a deeper command of English structure.

• Inflectional suffixes mark tense or number.
• Derivational suffixes form words of new classes.
• Common inflectional examples: -s, -ed, -ing, -er.
• Derivational examples: -ness, -ment, -able, -ion.
• Inflectional suffixes never change word category.
• Derivational suffixes often shift part of speech.
• Inflectional endings are essential for grammar accuracy.
• Derivational forms strengthen word variety.
• Each suffix type serves a unique function.
• Both types enrich English expression.

Type	Function	Examples	Result
Inflectional	Grammar or number	plays, walked, running	Same meaning, new form
Derivational	New meaning or class	happiness, enjoyable	New word, new meaning
