An Etymological Dictionary of the German Language/Rock

by Friedrich Kluge

Rock, m., ‘coat, robe, petticoat,’ from MidHG. roc (gen. rockes), OHG. rocch, m., ‘outer garment, coat’; corresponding to the equiv. Du. rok, OFris. rok, AS. rocc, OIc. rokkr; the implied Goth. *rukka- is wanting. From the Teut. cognates is derived the Rom. class, Fr. rochet, ‘surplice’ (MidLat. roccus, ‘coat’), which again passed into E. (rochet). The early history of the Teut. cognates is obscure; allied to Rocken?.
