"impostor, cheat," mid-14c., from Anglo-French faiteor, faiture "evildoer; slothful person," apparently a specialized use of Old French faiture "sorcery, spell," literally "deed, action," from Latin facere "do, make, perform" (see factitious), an etymologically neutral term taken in a bad sense.[faitor etymology, faitor origin, 英语词源]
