c.1200, "glory, renown, fame earned," from Anglo-French honour, Old French honor (Modern French honneur), from Latin honorem (nominative honos, later honor) "honor, dignity, office, reputation," of unknown origin. Till 17c., honour and honor were equally frequent; the former now preferred in England, the latter in U.S. by influence of Noah Webster's spelling reforms. Meaning "a woman's chastity" first attested late 14c. Honors "distinction in scholarship" attested by 1782. Honor roll in the scholastic sense attested by 1872. To do the honors (1650s) originally meant the customary civilities and courtesies at a public entertainment, etc.
