The member of a household whoever work supplies the meals of family person who works well with their living
- one whoever earnings are the major supply of help for their dependents
also bread-winner, "one which supplies an income for other individuals, especially a family group," 1821, from the noun bread (most likely in a literal sense) + champion, from win (v.) in its feeling of "battle for, work on." Attested a little earlier in the day (1818) in good sense "skill or art through which one tends to make an income." Maybe not too far taken off the picture within root of lord (letter.).
