winnow: winnow: [OE] Etymologically, to winnow grain is to separate it from the chaff by means of the ‘wind’. The verb was coined in the Old English period from wind. The same notion underlay Latin ventilāre ‘winnow’ (source of English ventilate), which was derived from ventus ‘wind’ (a relative of English wind).

winnow (v.): late 14c., from Old English windwian "to fan, winnow," from wind "air in motion, paring down," see wind (n.1). Cognate with Old Norse vinza, Old High German winton "to fan, winnow," Gothic diswinþjan "to throw (grain) apart."
