What does fulminator mean?
A fulminator is a person who denounces, protests, or complains loudly and vehemently — a strident critic prone to thunderous tirades. The word derives from the verb 'fulminate,' which itself comes from Latin fulmen, meaning lightning or thunderbolt, so a fulminator is figuratively someone who hurls verbal thunderbolts. In modern usage the term is rare and largely confined to literary or journalistic writing, where it typically carries a faintly mocking tone: a fulminator is someone whose rhetoric is dramatic and forceful, sometimes impressively so, but often more heated than persuasive. It might describe an indignant columnist, a perpetual objector at meetings, or a firebrand orator. The word is useful precisely because it names not just criticism but criticism of a particular kind — loud, sustained, and theatrical — making it a colorful alternative to plainer terms like critic or opponent.

Before it meant a ranting critic, 'fulminate' literally meant lightning — the word descends from Latin fulmen, a thunderbolt hurled from the sky.
