The word "deny" comes from Old French denoyer, which was borrowed into Middle English around 1300 with the meaning to repudiate or refuse something. Its roots trace back to Latin negare ("to refuse"), combining a prefix meaning "away" and a verb for saying no, ultimately deriving from an ancient Indo-European root related to negation.
