n. the state or condition of being impossible

The word "impossibility" traces back to Latin roots. The prefix "im-" (a variant of "in-") negates the following morpheme, "poss," derived from Latin "posse" (to be able). The suffix "-ibility" (from Latin "-ibilitas") forms abstract nouns indicating capacity or state. Combined, the morphemes logically construct the meaning "the state of not being able to happen." Over time, the word evolved through Old French "impossibilité" before entering Middle English, retaining its core structure.
