What does declinable mean?
"Declinable" is an adjective used mainly in linguistics to describe a word — typically a noun, pronoun, or adjective — that changes its form to express grammatical categories such as case, number, or gender. Latin, Russian, and German are rich in declinable words, whereas English has shed most of its inflectional endings, leaving only remnants like possessive 's and plural -s. The term derives from the verb "to decline," which itself comes from the Latin declinare, "to bend away or turn aside"; grammarians adopted the image of a word "bending" through its various forms. In rare non-technical use, "declinable" can also mean simply capable of being declined or refused, as in a proposal one may turn down. The word carries a formal, scholarly register and is most at home in textbooks, grammars, and discussions of classical or inflected languages, where its opposite, "indeclinable," marks words that keep a single form regardless of context.

Etymology of declinable
Declinable derives from the verb "decline," borrowed into Middle English from Old French decliner, which comes from the Latin declinare, meaning "to bend away, turn aside, or lean from" — formed from de- ("away") plus clinare ("to bend or lean"). Grammarians extended the literal sense of bending to the way nouns and adjectives bend through their case forms, so that a declinable word is one capable of such inflection. The same Latin root gives English a family of related words including inclination, recline, and proclivity.
How declinable is actually used
"Declinable" belongs chiefly to formal linguistic and grammatical writing, where it contrasts with "indeclinable." Outside grammar it appears rarely and can sound stilted; writers usually prefer phrasings such as "an offer that could not be refused."
Easily confused with declinable
"Definable" means capable of being defined or described precisely, whereas "declinable" refers either to grammatical declension or to the capacity to be declined or refused.
