Etymology: "Declinable" is a plain formation: the verb "decline" with the suffix "-able," meaning "able to be." Because the suffix passed through Latin "-bilis" and "-ābilis" and then Old French "-able" before reaching English, the ending carries a long ancestry. The sense is precise: a declinable word is one that changes its form through inflection, such as a Latin noun that shifts its endings for case, number, or gender. The core verb "decline" comes from Old French "decliner," from Latin "declinare," meaning "to bend or turn away." The grammatical sense arose because Latin scholars used the verb to describe how a noun was "bent" through its case forms, so the word shifted from physically turning aside to describing a pattern of endings.
