The rear wall of a room, building, or structure; in handball and squash, the wall at the back of the court.
From 'back' (Old English bæc) + 'wall' (Old English weall, from Latin vallum). A straightforward compound describing spatial position.
In racquet sports, the backwall is the nemesis of poor players but the salvation of good ones—a ball that bounces off the backwall deep in the court requires advanced anticipation and footwork, making it a teaching tool in sports fundamentals.
