A debut is someone's first public appearance or performance in a particular role. When a new movie actor appears on screen for the first time, that's their debut. When a band plays their first concert, they're making their debut. The word comes from French and originally meant “first” or “beginning.”

You'll often hear about debut albums (a musician's first album), debut novels (an author's first published book), or someone making their Broadway debut (their first time performing in a Broadway show). A debutante is a young woman making her formal debut into high society, traditionally at a special ball.

The word suggests something significant: a debut marks the moment when someone steps into a new arena where others will notice and judge their work. A student giving their first speech in front of the whole school is making a debut as a public speaker. The excitement and nervousness of a debut comes from knowing this first impression matters.

People also use debut as a verb: a player might debut for their team in an important game, or a new technology might debut at a major conference. Whether it's your debut performance in the school play or the debut of a new invention, the word captures that crucial moment of showing the world what you can do.
