Hypocrisy

Hypocrisy, pretence, or false assumption of a high character, especially in regard to religious belief or practice. The Greek ὑπόκρισις, from which the word is derived through the Old French, meant primarily the acting of a part on the stage, from ὑποκρίνεσθαι, to give an answer, to speak dialogue, play a part on the stage, hence to practice dissimulation.
