A mortise is a rectangular or square hole cut into a piece of wood or other material. It is designed to receive a corresponding tenon, which is a projecting piece that fits into the mortise to create a strong joint. This technique is commonly used in woodworking and furniture making to ensure stability and durability in structures. Mortises can vary in size and depth, depending on the specific requirements of the project. They are often found in traditional joinery methods, such as in the construction of doors, frames, and cabinets. The combination of a mortise and tenon joint is known for its strength and resistance to pulling apart, making it a favored choice among carpenters and woodworkers.
