brainstorm n.

also brain-storm, by 1861 as a colloquial term for "fit of acute delirious mania; sudden dethronement of reason and will under stress of strong emotion, usually accompanied by manifestations of violence," from brain (n.) + figurative use of storm (n.).

The sense of "brilliant idea, mental excitement, fit of mental application," is by 1934 and seems to have evolved from the earlier sense:

Modern radio broadcasting is replete with examples of the resourcefulness, daring and hair-trigger thinking of the men who handle the big news breaks and special programs for the networks — the "brainstorm boys" the announcers and engineers call them. Eye-witness accounts of federal agents surrounding a gang lair, word pictures of dust storms, stratosphere flights, floods and fires — these are but a few of the programs brought to radio audiences by the brainstorm squad. [Popular Mechanics, July 1936]

The verbal meaning "make a concerted attack on a problem, involving spontaneous ideas," is by 1947. Related: Brainstormed; brainstorming.

Entries linking to brainstorm brain n. "soft, grayish mass filling the cranial cavity of a vertebrate," in the broadest sense, "organ of consciousness and the mind," Old English brægen "brain," from Proto-Germanic bragnan (source also of Middle Low German bregen, Old Frisian and Dutch brein), a word of uncertain origin, perhaps from PIE root mregh-m(n)o- "skull, brain" (source also of Greek brekhmos "front part of the skull, top of the head"). But Liberman writes that brain "has no established cognates outside West Germanic" and is not connected to the Greek word. More probably, he writes, its etymon is PIE bhragno "something broken." The custom of using the plural to refer to the substance (literal or figurative), as opposed to the organ, dates from 16c. The figurative sense of "intellectual power" is from late 14c.; the meaning "a clever person" is recorded by 1914. To have something on the brain* "be extremely eager for or interested in" is from 1862. Brain-fart "sudden loss of memory or train of thought; sudden inability to think logically" is by 1991 (brain-squirt is from 1650s as "feeble or abortive attempt at reasoning"). An Old English word for "head" was brægnloca, which might be translated as "brain locker." In Middle English, brainsick (Old English brægenseoc) meant "mad, addled." storm n. Old English storm "violent disturbance of the atmosphere, tempest; onrush, attack, tumult; disturbance," from Proto-Germanic sturmaz "storm" (source also of Old Norse stormr, Old Saxon, Middle Low German, Middle Dutch, Dutch storm, Old High German sturm, German Sturm), from PIE stur-mo-, from root *(s)twer- (1) "to turn, whirl." Old French estour "onset, tumult," Italian stormo "a fight" are Germanic loan-words. Figurative (non-meteorological) sense was in late Old English. Storm-wind is from 1798. Storm-door first recorded 1872; storm-water is from 1847; storm-window is attested from 1824. Storm surge attested from 1872.
