1175-1225;Middle Englishipocrite < Old French < Late Latinhypocrita < Greekhypokritḗs a stage actor, hence one who pretends to be what he is not, equivalent to hypokrī́(nesthai) (see hypocrisy) + -tēs agent suffix
c.1200, ypocrite, from Old French ypocrite (12c., Modern French hypocrite), from Church Latin hypocrita, from Greek hypokrites "stage actor, pretender, dissembler," from hypokrinesthai (see hypocrisy).
one who puts on a mask and feigns himself to be what he is not; a dissembler in religion. Our Lord severely rebuked the scribes and Pharisees for their hypocrisy (Matt. 6:2, 5, 16). "The hypocrite's hope shall perish" (Job 8:13). The Hebrew word here rendered "hypocrite" rather means the "godless" or "profane," as it is rendered in Jer. 23:11, i.e., polluted with crimes.
