Crash
late Middle English: imitative, perhaps partly suggested by craze and dash.
wiktionary
From Middle English crasshen, crasschen, craschen(“to break into pieces”), of uncertain origin. Perhaps from a variant of earlier *crasken, from crasen(“to break”) + -k(formative suffix); or from earlier *craskien, *craksien, a variant of craken(“to crack, break open”) (for form development compare break, brask, brash).
Of uncertain origin; perhaps compare Russian крашени́на(krašenína, “coarse linen”).
