c.1200, “mild, gentle, kind courteous,” from Old French debonaire, from de bon’ aire “of good race,” originally used of hawks, hence, “thoroughbred” (opposite of French demalaire). Used in Middle English to mean “docile, courteous,” it became obsolete and was revived with an altered sense of “pleasant, affable” (1680s).
