An Etymological Dictionary of the German Language/Annotated/scheuern
scheuern, verb ‘to scour, rub,’ early Modern High German (unknown to Upper German, the term used being fegen), formed from Middle German and Low German schüren; compare Dutch schuren (Middle English scouren, English to scour, borrowed from Dutch?), Danish skure, Swedish skura. Although the word is wanting iu the Old Teutonic dialects, it need not be regarded as borrowed from Middle Latin scurare (Latin ex-curare), Italian scurare, French écurer, ‘to scour.’
