| thunder (thŭn'dər) Pronunciation Key
The explosive noise that accompanies a stroke of lightning. Thunder is a series of sound waves produced by the rapid expansion of the air through which the lightning passes. Sound travels about 1 km in 3 seconds (about 1 mi in 5 seconds). The distance between an observer and a lightning flash can be calculated by counting the number of seconds between the flash and the thunder. See Note at lightning. |
steal someone's thunder
Use or appropriate another's idea, especially to one's advantage, as in It was Harold's idea but they stole his thunder and turned it into a massive advertising campaign without giving him credit. This idiom comes from an actual incident in which playwright and critic John Dennis (1657-1734) devised a "thunder machine" (by rattling a sheet of tin backstage) for his play, Appius and Virginia (1709), and a few days later discovered the same device being used in a performance of Macbeth, whereupon he declared, "They steal my thunder."
