TENON
One simple type of joint used in carpentry is a mortise and tenon. It is basically a projection carved at the end of one piece of wood that fits into a hole cut into the end of another. In the related dovetail joint, the projecting tenon is not rectangular but is cut at a bias, so that when the dovetails are joined they resist being pulled apart. You’ll see dovetail joints in drawers around the house.
