Word Origin

Late Middle English: from Latin “fulminatus,” past participle of “fulminare” meaning “to strike with lightning,” from “fulmen” meaning “lightning.”

Fun Fact

Fulminate originally described literal lightning strikes before evolving to describe explosive anger. The chemistry connection remains strong: fulminating compounds are highly unstable explosives that detonate from the slightest disturbance. Mercury fulminate was used in blasting caps and firearm primers precisely because it explodes so violently. When someone fulminates verbally, they’re essentially detonating—their words strike with lightning speed and explosive force. The Pope can issue a fulmination, a formal denunciation accompanied by excommunication, keeping the word’s most dramatic ecclesiastical use alive.
