debut
UK: ˈdeɪbjuː | US: deɪˈbjuː
n. a person's first appearance or performance in a particular capacity or role
vt. to present or introduce something for the first time
The word "debut" entered English in the 18th century from French début, which originally referred to the first stroke in a game (e.g., billiards) or the starting point of an action. The French term derived from débuter ("to lead off"), combining dé- (indicating origin) and but ("target"). Over time, it broadened to signify a first public appearance, retaining its core idea of "beginning at a marked point."
