JUMP + THE GUN = START TOO SOON?!
A real jump over a real gun? ❌
Leaving before the signal says "go"? ✅
The picture is simple: in a race, a runner waits for the sound of the starting gun. If they move before it, they've jumped the gun, and they may have to start again.
🎬 Picture the Situation

🎓 Common Learner Point
It's about timing, not speed. You can jump the gun and still act slowly. What matters is that you acted before the right moment.
It's usually a mild criticism. It says "too soon", but it isn't harsh.
Keep the verb form. Jump the gun, jumped the gun, jumping the gun. People don't say "jump a gun".
🕵️ Where Does It Come From? A Starting Gun
This is the OddLingo part: the racing story is well supported, but the dates differ.
What we can say:
- In running races, the start is signalled by a gun (or pistol). Starting before it is called jumping the gun.
- Sources record a similar phrase, beat the pistol, from about 1905, and the wording jump the gun by the 1940s. Merriam-Webster gives an earlier date, 1895, for the racing sense, but that isn't confirmed elsewhere.
- The figurative meaning, "doing something too soon", is recorded as early as 1921.
So the idiom is a good example of a sports phrase that walked out of the stadium and into everyday life.
💡 The OddLingo Trick
Picture a runner on the starting line with their foot a little too far forward. The gun hasn't fired, but they've already moved. That's jumping the gun.
If you want to remember it, link it to waiting: wait for the gun.
