Etymology

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).

Uncertain; perhaps compare Russian крашени́на (krašenína, “coarse linen”).
