naught (n.)

Old English nawiht "nothing," lit "no whit," from na "no" (from PIE root *ne- "no, not;" see un- (1)) + wiht "thing, creature, being" (see wight). Cognate with Old Saxon neowiht "nothing," Old High German niwiht, Gothic ni waihts. It also developed an adjectival sense in Old English, "good for nothing," which by mid-16c. had focused to "morally bad, wicked." In arithmetic, "the figure zero" from 1640s.
