Origin

From Middle English turnen, from Old English turnian, tyrnan (“to turn, rotate, revolve”), from Proto-West Germanic *turnēn (“to turn, lathe”) (also the source of German turnen and its derivatives) and Old French torner (“to turn”), both from Latin tornāre (“to round off, turn in a lathe”), from tornus (“lathe”), from Ancient Greek τόρνος (tórnos, “turning-lathe: a tool used for making circles”), from Proto-Indo-European *terh₁- (“to rub, rub by turning, turn, twist, bore”). Cognate with Old English þrāwan (“to turn, twist, wind”), whence English throw.
