hemp: [OE] Hemp is ultimately the same word as cannabis (as, bizarrely, is canvas, which was originally made from hemp). Both go back to a common ancestor which produced Persian kanab, Russian konóplya, Greek kánnabis (source of English cannabis), and a prehistoric Germanic *khanipiz or *khanapiz. From the latter are descended German hanf, Dutch hennep, Swedish hampa, Danish hamp, and English hemp. => cannabis
hemp (n.)
Old English hænep "hemp, cannabis sativa," from Proto-Germanic *hanapiz (cognates: Old Saxon hanap, Old Norse hampr, Old High German hanaf, German Hanf), probably a very early Germanic borrowing of the same Scythian word that became Greek kannabis (see cannabis). As the name of the fiber made from the plant, by c. 1300. Slang sense of "marijuana" dates from 1940s; though scientific use for the narcotic derived from hemp dates to 1870.
