debut

The word 'debut' entered English in the mid-18th century directly from the French noun 'début', meaning 'a first stroke' or 'beginning'. The French term itself derives from the phrase 'débuter', literally 'to lead off' in a game, which is composed of 'dé-' (from, off) and 'but' (goal, target). The core logic of the word, from its literal origin of making an opening move in a game, evolved seamlessly into its modern abstract meaning of a first public appearance or performance, carrying the sense of a formal and significant beginning.

The word 'debut' is a simplex loanword from French. It cannot be meaningfully segmented into smaller, independent morphemes using its current English spelling.
