LowTechnical / Specialised
Definition
Meaning
A strong woodworking joint where a tenon (a projecting piece) is inserted into a matching cavity (the mortise), typically secured with glue or a peg.
Can refer to the principle of a sturdy, interlocking connection more broadly, used metaphorically in fields like engineering or anatomy to describe a similar locking mechanism.

Examples
By Part of Speech
verb
British English
- First, you must mortise the stile to receive the tenon.
American English

Examples
By CEFR Level
- A mortise joint is very strong and is often used in wooden tables and chairs.
- The carpenter used a chisel and mallet to carefully cut the mortise before fitting the tenon, creating a classic mortise joint.
- Unlike modern bracket-based assembly, traditional timber framing relies on the structural integrity of the mortise joint, often secured with nothing more than an oak peg.
Learning
Memory Aids
Mnemonic
Imagine a castle's MORtar holding bricks together firmly; a MORTISE holds a tenon with similar firmness in a wooden JOINT.
Conceptual Metaphor
A PRECISE AND SECURE CONNECTION IS AN INTERLOCKING FIT (e.g., 'Their skills were a perfect mortise joint, complementing each other flawlessly').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as просто 'соединение' (just 'connection'), which is too broad. The specific term is 'шиповое соединение' or 'соединение «шип-паз»'.
Common Mistakes
- Confusing 'mortise' with 'mortar' (the building material).
- Using 'mortise joint' to describe any strong joint, rather than specifically the mortise-and-tenon type.
- Misspelling as 'mortice joint' in American contexts.

FAQ
Frequently Asked Questions
Traditional tools include a chisel and mallet, a mortise gauge, and a brace and bit or drill. Modern workshops often use a dedicated mortising machine or a router with a jig.
Both are correct. 'Mortise' is standard in American English, while 'mortice' is a common variant in British English, though 'mortise' is also widely used in the UK.
Traditionally, once glued or pegged, it is designed to be permanent. A 'through' mortise joint with a removable wedge (a tusk tenon) is one type designed for disassembly.
Both are strong, interlocking wood joints. A mortise joint uses a rectangular tenon and cavity, while a dovetail uses fan-shaped tails and pins, often for joining corners (like in drawer construction).
