Английский Этимологический словарь - grape

- c.1250, from O.Fr. grape "bunch of grapes," from graper "pick grapes," from Frank. word for "hook" (cf. O.H.G. krapfo "hook"), from the notion of "vine hook for grape-picking." The vine is not native to England. The word replaced O.E. winberige "wine berry." Grapefruit first recorded 1693 in Hans Sloane's catalog of Jamaican plants; presumably it originated there from chance hybrids between other cultivated citrus. Grapeshot is from 1747; grapevine "rumor source" is 1862, from U.S. Civil War slang for "telegraph wires."
