Etymology
From Middle English not, nat, a variant of noght, naht (“not, nothing”), from Old English *nōht, nāht (“nought, nothing”), shortening of nōwiht, nāwiht (“nothing”, literally “not anything”), from Proto-West Germanic *naiwwiht, corresponding to ne (“not”) + ōwiht, āwiht (“anything”), corresponding to ā (“ever, always”) + wiht (“thing, creature”).
Cognate with Scots nat, naucht (“not”), Saterland Frisian nit (“not”), West Frisian net (“not”), Dutch niet (“not”), German nicht (“not”). Compare nought, naught and aught. More at no, wight, whit.
