I just read about the symbol of Venice, the winged lion of Venice. As a German the German word die Schwingen for wings came to my mind. English has the word in the verb to swing.The connection between wings and to swing is obvious. By means of its wings a bird can swing up into the air.
To my amazement, etymonline does not see the connection of "wing" with "to swing" and German schwingen and the noun die Schwingen. In my view etymonline gets on a wrong track by trying to make a connection with wind.
I would like to hear other views.
