Word Origin & Etymology

The sense 'to clean by rubbing' comes from Middle English scouren, borrowed from Middle Dutch schuren and Old French escurer, ultimately from Late Latin excurare ('to clean off'). The sense 'to search thoroughly' derives separately from Old French escourre, from Latin excurrere ('to run out').
