The joint type that involves a slot cut into one piece of wood to hold another piece is known as a mortise joint. In this joint, a rectangular hole, or mortise, is created in one piece of wood, while the other piece, known as the tenon, is shaped to fit snugly into this hole. This design allows for a strong, secure connection that is ideal for various applications in cabinetmaking, such as joining frames or legs to the top of furniture.

The mortise and tenon joint is celebrated for its strength and stability, particularly when used in structurally demanding applications. It is also commonly utilized in both traditional and modern woodworking, providing reliability in the construction of furniture and cabinetry.

In contrast, the dado joint is characterized by a groove cut across one board, allowing another board to fit into it, while lap joints involve overlapping two pieces of wood. The rabbet joint involves a notch cut along the edge of a piece of wood, which might seem similar but does not involve the deeper slot characteristic of a mortise.
