Etymology: "Longaevitas" is a Latin noun, built from "longus" ("long") and "aevum" ("age, lifetime, eternity"), with the abstract suffix "-itas" that turns an adjective into a noun of quality, much like English "-ity." Its sense, a long life or great age, is entirely transparent from those parts. The Latin noun is attested in classical and later Latin writing, and "aevum" is the same root that gives English "age" through Old French, as well as "eternal" through Latin "aeternus." So the word's second element carries a surprisingly wide family of meanings, from a single lifetime to unending time. In English the word is essentially a learned borrowing from Latin, used mainly in scientific, biological, and literary contexts, where it describes exceptional lifespan in organisms.
