What does fulmination mean?
Fulmination is a noun denouncing the act of delivering a violent, thunderous verbal attack — a tirade or denunciation poured forth with evident fury and little restraint. To engage in fulmination is to rail against a person, policy, or institution at high volume and temperature; the word suggests rhetoric that is more explosive than persuasive. Its figurative force draws on its literal origins: Latin fulmen means lightning bolt or thunderclap, so a fulmination carries the imagery of a storm hurled from on high. In modern usage it appears mostly in political commentary, journalism, and literary prose, often with a faint note of irony — describing a critic's fulminations implies the anger is loud, perhaps excessive, and possibly futile. It is also found in historical contexts referring to actual lightning or explosions, though this sense is now rare. For writers seeking a term that conveys indignation at full volume, fulmination offers precision and dramatic pedigree.

Before it meant a furious rant, 'fulmination' literally meant a lightning strike — the word still carries the thunder.

Etymology of fulmination
Fulmination derives from Latin fulminare ('to lighten' or 'to hurl thunderbolts'), rooted in fulmen, the lightning bolt. Originally it denoted literal thunder and lightning, and later explosive detonations — chemists still speak of 'fulminating' compounds like mercury fulminate. By the early 17th century English usage had extended the term to figurative thunder: furious verbal denunciations, a sense popularized by religious and political polemic. Cognate forms include fulminate (verb) and fulminic (as in fulminic acid).
How fulmination is actually used
Formal to literary register; often used of public figures' angry speeches. The plural 'fulminations' is common for repeated outbursts. Carries a connotation of theatrical, somewhat excessive rage rather than measured criticism.
Easily confused with fulmination
Despite the shared root with fulminates (explosive salts), the noun 'fulmination' in ordinary use refers to verbal outbursts, not chemical explosions.
