Winnow Has Old English Roots

Beginning as windwian in Old English, winnow first referred to the removal of chaff from grain by a current of air. This use was soon extended to describe the removal of anything undesirable or unwanted (a current example of this sense would be "winnowing out sensitive material"). People then began using the word for the selection of the most desirable elements (as in "winnowing out the qualified applicants"). The association of winnow with the movement of air also led to the meanings "to brandish" and "to beat with or as if with wings," but those uses are now rare. The last meanings blew in around the beginning of the 19th century: they are "to blow on" and "to blow in gusts."
