O.E. nan "not one, not any," from ne "not" (see no) + an "one." Cognate with O.S., M.L.G. nen, O.N. neinn, M.Du., Du. neen, O.H.G., Ger. nein "no," and analogous to L. non- (see non-). As an adj., since c.1600 reduced to no except in a few archaic phrases, especially before vowels, such as none other, none the worse.
