originFrom Middle English adjectif, adjective, from Old French adjectif, from Latin adiectivus, from adiciō + -īvus, from ad- (“to, towards, at”) + iaciō (“throw”). The Latin word adiectivus in turn was a calque of Ancient Greek ἐπιθετικόν (epithetikón, “added”), a derivative of the compound verb ἐπιτίθημι (epitíthēmi), from which also comes epithet.
