"worthless stuff," 1338, junke "old cable or rope" (nautical), of uncertain origin, perhaps from O.Fr. junc "rush," from L. juncus "rush, reed." Nautical use extended to "old refuse from boats and ships" (1842), then to "old or discarded articles of any kind" (1884). The verb meaning "to throw away as trash, to scrap" is from 1916. Junkie "drug addict" is attested from 1923, but junk for "narcotic" is said to be older. Junk food is from 1973; junk art is from 1966; junk mail first attested 1954.
