Word Origin for ameliorate
1550s, "to make better," back-formation from melioration or else from Late Latin melioratus, past participle of Latin meliorare "improve," from melior "better," used as comparative of bonus "good," but probably originally meaning "stronger," from PIE root *mel- "strong, great, numerous" (see multi-). Related: Meliorated; meliorating; melioration; meliorative.
1728, perhaps a back-formation from amelioration on pattern of French améliorer. The simpler form meliorate was used in Middle English. Related: Ameliorated; ameliorating.
