Word Origin & History

scour  (1)
"cleanse by rubbing," c.1300, from M.Du. scuren "to polish, clean," and from O.Fr. escurer, both from L.L. excurare "clean off," lit. "take good care of," from L. ex- "out" + curare "care for" (see cure). Possibly originally a technical term among Flemish workmen in England.

scour  (2)
"move quickly in search of something," 1297, probably from O.N. skyra "rush in," related to skur "storm, shower." Perhaps infl. by or blended with O.Fr. escorre "to run out," from L. excurrere (see excursion). Sense development probably infl. by scour (1).
