Origin & History of “rack”
English has no fewer than four distinct words rack. The oldest, ‘framework’ (14th c.), was borrowed from Dutch rak, which was probably a derivative of the middle Dutch verb recken ‘stretch’. Rack ‘destruction’ (16th c.), now used only in the phrase rack and ruin, is a variant of wrack, which is closely related to wreak and wreck. Rack, or wrack, ‘mass of wind-driven cloud’ (14th c.) was probably acquired from Old Norse (Swedish has the probably related rak). And rack ‘drain wine off its lees’ (15th c.) was borrowed from Provençal arracar, a derivative of raca ‘dregs’.
