The English prefix non- , which means ânot,â appears in hundreds of English vocabulary words, such as non sense, non fat, and non returnable. You can remember that the prefix non-means ânotâ via the word non poisonous, for a substance that is non poisonous is ânotâ poisonous.
Word Origin and History for non-Expand prefix meaning not, lack of, or sham, 14c., from Anglo-French noun-, from Old French non-, from Latin non not, by no means, not at all, not a, from Old Latin noenum not one (*ne oinom, from PIE *ne not + *oi-no-; see one). In some cases perhaps from Middle English non not (adj.), from Old English nan (see not).
