debut definition by American Heritage Dictionary
- A first public appearance, as of a performer.
- The formal presentation of a young woman to society.
- The beginning of a course of action: the debut of a new foreign policy.
Origin: French début, from débuter, to give the first stroke in a game, begin : dé-, from, away (from Old French de-; see de-) + but, goal, target (from Old French butte; see butt3).Usage Note: Debut is widely used as a verb, both intransitively (Her new series will debut next March on network television) and transitively (The network will debut her new series next March). These usages are well established in connection with entertainment and the performing arts but are not entirely acceptable when used of other sorts of introductions, as of products (The company will debut the new six-cylinder convertible next fall) or publications (The national edition of the newspaper debuted last summer), probably because of the association of the form with the language of show-business publicity.
