Word Origin & History
rack"clouds driven before the wind," c.1300, also "rush of wind, collision, crash," possibly from O.E. racu "cloud," reinforced by O.N. rek "wreckage, jetsam," or by influence of O.E. wræc "something driven." Originally a northern word, perhaps from an unrecorded Scand. cognate of O.E. racu. Often
EXPANDconfused with
wrack (q.v.), especially in phrase rack and ruin (1599). The distinction is that rack is "driven clouds;" wrack is "seaweed cast up on shore."
