derivation (linguistics)

In linguistics, derivation is the process of creating new lexemes from other lexemes, for example, by adding a derivational affix. It is a kind of word formation.A derivational suffix usually applies to words of one syntactic category and changes them into words of another syntactic category. For example, the  English derivational suffix -ly changes adjectives into adverbs (slow → slowly).Some examples of English derivational suffixes:adjective-to-noun: -ness (slow → slowness)adjective-to-verb: -ise (modern → modernise)noun-to-adjective: -al (recreation → recreational)noun-to-verb: -fy (glory → glorify)verb-to-adjective: -able (drink → drinkable)verb-to-noun: -ance (deliver → deliverance)
