also bread-winner, "one who supplies a living for others, especially a family," 1821, from the noun bread (probably in a literal sense) + winner, from win (v.) in its sense of "struggle for, work at." Attested slightly earlier (1818) in sense "skill or art by which one makes a living." Not too far removed from the image at the root of lord (n.).
