The story

From Middle English non- (‘not, lack of, failure to’), from Middle English non (“no, not any; not, not at all”, literally “none”) and Old English nān- (prefix), both from Old English nān (‘no, not any’), from Proto-West Germanic *nain, from Proto-Germanic *nainaz (‘none, nought, zero’), see none. Merged with and reinforced by Middle English non- (‘not’), from Old French non- and Medieval Latin nōn (‘not’), from Old Latin noinu, noinom, from ne oinom (‘not one’).
