Is there really a downswing in a golf swing?

The word downswing has been frequently used in the game of golf. Almost everyone like amateurs, professionals, instructors and coaches, use the word downswing almost every time they discuss the downward motion, prior to impact. But, is there really a downswing in a golf swing? I choose to say none.

A swing, as defined in the dictionary, is a backward and forward motion, to and fro, back and forth, or a rotary motion, from a fixed point or an axis.In golf, in order to make the shot, it is necessary to execute a swing. So, one swing is equivalent to one shot.
