Search online for the origin of break a leg and you’ll find a dozen confident answers. It comes from the man who shot Abraham Lincoln. It comes from a famous French actress. It comes from the way actors bow. Most of these stories have one thing in common: there’s no evidence for them.
So let’s start with what we actually know, and then look at how to use this cheerful, slightly strange wish.
What it means
Break a leg! means “Good luck!” It’s said to someone just before a performance: a play, a concert, a dance show, a speech. Nobody wants the person to get hurt. It’s a friendly wish dressed up as a bad one.
Popular stories that don’t hold up
- John Wilkes Booth. The actor who shot President Lincoln in 1865 really did break his leg as he escaped. But word historian David Wilton of Wordorigins.org finds no connection between that event and the expression, which appears in print decades later.
- Sarah Bernhardt. The famous French actress had a leg amputated in 1915. Some say actors were invoking her. Both Wilton and Gary Martin of The Phrase Finder dismiss this as fanciful.
- Bowing, curtains and coins. Other theories say “break” means bending your knee to bow, or that “legs” are stage curtains, or that you kneel to pick up coins thrown by a happy audience. Wilton calls the bowing idea unsubstantiated, and nobody has found early writing that links any of these pictures to the phrase.
What the written record shows
Here’s the evidence that researchers have actually found:
- 1921: The Irish writer Robert Lynd mentions wishing someone “break your leg” in an article about superstitions in horse racing, where wishing a rider good luck was thought to be unlucky.
- 1948: An American newspaper, the Charleston Gazette, explains that actors believe saying “good luck” is bad luck, so they say “I hope you break a leg” instead. Both Wilton and Martin treat this as the earliest clear theatrical example in print.
- A German cousin: German has a similar wish, Hals- und Beinbruch (“neck and leg break”), and it appears earlier. Wilton traces it to German hunting talk around 1902. Some researchers think the English phrase may have come from German or Yiddish speakers in the theater world, but this has not been proven.
The honest answer, then: break a leg is a 20th-century expression, it became popular in American theater, and it grew out of the old idea that wishing someone good luck out loud might jinx them. Exactly how it started, nobody knows for sure.
Who can say it, and when
Here’s what a dictionary won’t tell you. Break a leg has a very specific timing and audience.
- Say it before, not after. It’s for the moments right before someone goes on stage. After the show, say “Great job!” or “You were amazing!”
- It works best for performances. Plays, concerts, recitals, speeches, presentations, auditions. People also use it playfully for job interviews or exams.
- Avoid it for physical risks. Telling a friend “Break a leg!” before a ski trip or a football game sounds like a bad joke, because a real broken leg is possible. Just say “Have fun and be careful!”
- Don’t change the words. “Break your leg” or “Break two legs” sounds odd. The fixed form is break a leg.
- It’s informal and warm. It’s fine with friends, classmates and coworkers.
Backstage
Nina: I can’t breathe. What if I forget my lines?
Tom: You won’t. You’ve practiced for six weeks.
Nina: Okay. Okay. Here I go.
Tom: Break a leg! I’ll be in the second row.
Good-luck wishes in other forms
- Good luck!: the standard wish, fine almost anywhere (except, some say, backstage)
- Knock ’em dead!: very casual, “impress your audience completely”
- Fingers crossed!: “I’m hoping for a good result,” often said about an outcome you’re waiting for
- You’ve got this!: “I believe in you,” very common among friends

A Note from Daniel
What I find most attractive about this idiom is its logic. Wishing someone harm, when said with affection and an understanding look, can actually feel warmer than a sincere good luck. It shows that language doesn’t always work by saying exactly what it means. Sometimes, the most genuine encouragement comes in a playful form, even if it appears a bit off. If you have a story about a “break a leg” moment—maybe someone said it to you before something important, or you said it to someone else—I’d love to hear it.
