Word Origin & History
innuendo
1678, "oblique hint, indiscreet suggestion," usually a depreciatory one, from L. innuendo "by meaning, pointing to," lit. "giving a nod to," abl. of ger. of innuere "to mean, signify," lit. "to nod to," from in- "at" + nuere "to nod." Originally a legal phrase (1564) from M.L., with the sense of "to wit." It often introduced the derogatory meaning alleged in libel cases, which influenced its broader meaning.
