crash: [14] Crash suddenly appeared from nowhere in Middle English (meaning ‘break in pieces noisily’), with apparently no relatives in other Germanic languages. Its form suggests that it originated in imitation of the sound of noisy breaking, but it has been further suggested that it may be a blend of craze and dash. The financial or business sense of the noun, ‘sudden collapse’, is first recorded in the early 19th century in the writings of Samuel Taylor Coleridge. [crash etymology, crash origin, 英语词源]
