Etymology: "Declensional" is a plain formation: the noun "declension," with the adjective-forming suffix "-al" added to it. A declension is the set of forms a noun, pronoun, or adjective takes as its ending changes with case, number, or gender, and the adjective simply means relating to or characterised by such changes. Its parts are easy to read: "declension" comes from the Latin "declinatio," a bending away or inflection, and "-al" is the common English suffix meaning "of or relating to," as in "national" or "musical."

Synonyms: inflectional, grammatical, morphological
