'brainstorming' originates from English, specifically the word 'brainstorm', where 'brain' meant 'mind' and 'storm' meant 'a sudden attack or outburst'.

'brainstorm' changed from the English word 'brain' and 'storm' and eventually became the modern English word 'brainstorming'.

Initially, it meant 'a sudden attack of the mind', but over time it evolved into its current meaning of 'a group creativity technique'.
