leather on willow
In some articles, when talking about cricket, the saying of "leather on willow" always shows up. Could anyone explain this to me? Where does it derive from and what does it mean? Thank you very much. :)

Question

Answer

The cricket bat is made of wood from the willow tree, and the ball is covered with leather.
When the ball is struck, we hear the sound of willow on leather.

The phrase is more often said, "willow on leather" than "leather on willow," because the bat is taking the action on the ball.
