What is Mortis?
A mortise is a cut-out space made in a piece of wood or another material so that another piece can fit into it.
Definition
Purpose
A mortise is usually created when two parts need to fit together. In woodworking, it is commonly paired with a tenon to form what is called a ‘mortise and tenon’ joint.
This type of joint is often found in furniture, doors, and timber structures. Mortises are also used for mortise locks, which are installed inside a pocket cut into the door rather than attached to the surface.
Examples of Use
- Furniture making: Table legs and chair frames often use mortise and tenon joints to connect pieces of wood.
- Door hardware: A mortise is also used to cut into a door to install a mortise lock.
- Wood framing: Builders use mortises to join structural wood members together.

Notes
