Question

derivational suffixes write a short note

Answer 1

Derivational morphology often involves the addition of a derivational suffix or other affix. Such an affix usually applies to words of one lexical category (part of speech) and changes them into words of another such category. For example, the English derivational suffix -ly changes adjectives into adverbs (slow → slowly).

ex.
adjective-to-adverb: -ly (personal - personally)
noun-to-verb: -fy (glory → glorify)
