A person who practices the most extreme form of hypocrisy; someone who is preeminently false or deceitful in their presentation.
From arch- (supreme, chief) + hypocrite (a person who practices hypocrisy). Hypocrite comes from Old French hypocrite, from Late Latin hypocrita, from Greek hypokrites (actor, pretender).
Victorians used this term as a serious moral accusation—an archhypocrite wasn't just someone who occasionally lied, but a person whose entire public persona was a carefully constructed fake, making them almost laughably transparent to anyone paying attention.
