hypocrisy

Etymology

From Middle English ipocrisie, from Old French ypocrisie, from Late Latin hypocrisis, from Ancient Greek ὑπόκρισις (hupókrisis, “answer, stage acting, pretense”), from ὑποκρίνομαι (hupokrínomai, “I answer (a fellow actor on stage), play a part, dissemble, feign”), from ὑπό (hupó, “under, equivalent of the modern "hypo-" prefix”) + the middle voice of κρίνω (krínō, “I separate, judge, decide”). Displaced native Old English līċettung.
