An Etymological Dictionary of the German Language/scheuern
scheuern, vb. ‘to scour, rub,’ early ModHG. (unknown to UpG., the term used being fegen), formed from MidG. and LG. schüren; comp. Du. schuren (MidE. scouren, E. to scour, borrowed from Du.?), Dan. skure, Swed. skura. Although the word is wanting iu the OTeut. dials., it need not be regarded as borrowed from MidLat. scurare (Lat. ex-curare), Ital. scurare, Fr. écurer, ‘to scour.’
