Etymology

Origin of debut

1745–55; < French début, derivative of débuter to make the first stroke in a game, make one's first appearance, equivalent to dé- de- + -buter, verbal derivative of but goal; see butt ²

Explanation

A debut is a first appearance, a launch, or public introduction. So before you make your big debut at the office, check and make sure you don't have spinach in your teeth. Perhaps you’ve heard of debutantes making their official debut into society, or actresses and actors making their debut on stage. A fun fact: debut and premiere are often thought to be interchangeable, but they’re not. A debut, as you now know, is a first public appearance. But a premiere, while also a “first,” isn't necessarily live. When a movie opens or an interview is broadcast for the first time, they're called premieres.
