What is mortise-and-tenon joinery and its purpose?

• A. A strong interlocking joint using a mortise hole and tenon plug.
• B. A decorative groove that is purely aesthetic.
• C. A type of glue used in frame joints.
• D. A rounded joint.

Answer: (B)

Mortise-and-tenon joinery is a traditional woodworking technique where the end of one piece (the tenon) fits precisely into a corresponding cavity (the mortise) in the adjoining piece. The two parts are aligned and joined, often with glue and sometimes with a peg or wedge for extra security. This creates a strong mechanical interlock that resists being pulled apart and helps keep the assembly square over time, making it ideal for frames, furniture, doors, and other structural components. It’s about a functional, sturdy connection rather than decoration, so describing it as a decorative groove or a rounded joint doesn’t capture how the joint actually transfers loads and maintains alignment.
