c. 1300, "wicked, base, cowardly," from Old North French caitive "captive, miserable" (Old French chaitif, 12c., Modern French chétif "puny, sickly, poor, weak"), from Latin captivus "caught, taken prisoner," from captus, past participle of capere "to take, hold, seize," from PIE root *kap- "to grasp." Its doublet, captive, is a later, scholarly borrowing of the same word. In most Romance languages, it has acquired a pejorative sense (Spanish cautivo, Italian cattivo).
