From Middle English nothyng, noon thing, non thing, na þing, nan thing, nan þing, from Old English nāþing, nān þing (“nothing”, literally “not any thing”), equivalent to no + thing. Compare Old English nāwiht (“nothing”, literally “no thing”), Swedish ingenting (“nothing”, literally “not any thing, no thing”).
