Quick answer: “Steal someone's thunder” means to take attention or credit away from someone, overshadowing their success or announcement.
Steal someone's thunder means to take the attention, praise, or recognition that rightfully belongs to another person — typically by making an announcement, doing something dramatic, or appearing at a moment that was meant to be theirs. The result is that the original person loses their spotlight, even if that was not the intention.
Meaning
When you "steal someone's thunder", you divert the attention or glory that was due to them. This often happens around announcements, achievements, or special occasions. A colleague who shares your news before you can, a guest who upstages the host, or a headline that drowns out a planned reveal — all of these steal someone's thunder.
The phrase emphasises that what was taken was not just attention but something the other person had worked for or was entitled to. There is an implicit sense of injustice: the moment belonged to them, and someone else claimed it. The theft can be deliberate or entirely accidental.
Origin and History
The idiom has a remarkably specific and well-documented origin. In the early 1700s, the English playwright and critic John Dennis invented a mechanical device that produced a realistic sound of thunder for use in his play Appius and Virginia (1709). The play was not a success and was quickly taken off the stage.
Shortly afterwards, Dennis attended a production of Macbeth at the same theatre and heard his thunder device being used. Furious, he reportedly stood up and declared something to the effect of: "Damn them! They will not let my play run, but they steal my thunder!" The story spread, and the phrase entered common usage as a way to describe someone taking what another had created or deserved. Learners who want to check other figurative expressions can consult general reference works such as the Cambridge Dictionary, which document how such idioms are used today.
Over the following centuries the idiom broadened from literal plagiarism of theatrical effects to any situation where someone's rightful moment of recognition is taken by another. It is now used widely in English across the UK, the US, Australia, and beyond.

The phrase works across a wide range of registers, from casual conversation to journalism. It is neutral in British and American English and does not carry strong regional flavour, making it safe to use in most English-speaking contexts. In formal or academic writing, prefer "overshadow", "upstage", or "take credit away from".
