What is a mortice and tenon joint?

• A. A joint with a mortice and tenon
• B. A joint formed by screws and dowels
• C. A joint created by rebates
• D. A butt joint reinforced with nails

Answer: (A)

A mortise and tenon joint is a traditional woodworking method where a tenon, a protruding tongue at the end of one piece, fits snugly into a corresponding mortise, a cavity cut into the adjoining piece. The joint is square and interlocking, with the shoulders on the tenon helping to align the pieces and often glue added for extra strength. This setup creates a very strong connection that resists pulling apart and twisting, making it ideal for frames, tables, and chairs. Other methods rely on different principles. Screws and dowels use fasteners to hold pieces together rather than an interlocking profile. Rebates are recesses cut into a piece to accept a panel, not a tongue-and-slot join. A butt joint with nails is a simple edge-to-edge connection without the interlocking geometry that provides added strength.
