Etymology

Origin of fulminate

First recorded in 1375–1425; late Middle English fulminaten < Latin fulminātus, past participle of fulmināre “to hurl thunderbolts, thunder,” equivalent to fulmin-, stem of fulmen “thunderbolt, lightning” + -ātus -ate 1


Explanation

Watch a bomb fulminate or explode and hope you're under safe cover. Have your parents fulminate or blow up at you for coming home past curfew and hope you're not grounded for too long. The word fulminate is made up of the Latin root fulmen meaning "lightning flash." Look up at the sky during a violent thunderstorm and chances are you'll catch thunder and lightning fulminate or explode loudly and violently overhead. But you needn't look to the sky alone for this kind of intensity. If you find yourself in a room with passionate Republicans and Democrats debating, you might see them fulminate or severely rail against each other's beliefs.
