Origin & History of “fault”

like fail, fallacy, fallible, and false, fault comes ultimately from Latin fallere ‘deceive, fail’. Its past participle formed the basis of a vulgar Latin noun *fallita ‘failing, falling short’, which passed into English via Old French faute in the sense ‘lack, deficiency’. The notion of ‘moral culpability’ does not seem to have become incorporated into the word until the late 14th century.
