"ancient tool for scraping the skin after a bath," 1581, from L.
strigilis "horse-comb," from
stringere (1) "draw along a surface, graze, wound, strip off, rub," from PIE base
*streig- (cf. L.
striga "stroke, strike, furrow,"
stria "furrow, channel;" O.C.S.
striga "shear;" O.E.
stracian "to stroke;" Ger.
streichen "to stroke, rub"). Etymologists dispute over whether this is connected to L.
stringere (2), root of
strain (v.).
