Etymology

Etymology 1

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”).

Etymology 2

From Latin nona (“nine”).
