early 13c., from Anglo-Fr. and O.Fr. venim, from V.L. *venimen, from L. venenum "poison, drug, potion," perhaps ultimately connected to venus "erotic love" (see Venus), in which case the original meaning might have been "love potion." The meaning "bitter, virulent feeling or language" is first recorded c.1300.
