n
a hole cut in a piece of wood or other material to receive the end of another piece (a tenon), forming a joint.
v
to join or fasten securely with a mortise and tenon joint.
Etymology
the word "mortise" entered english in the late 14th century from the old french term "mortaise," meaning a mortise or a hole for a tenon. the origin of the old french word is uncertain but is likely derived from arabic "murtazz," meaning "fastened" or "fixed," which itself comes from the verb "razza," to cut a mortise. this etymological journey, from arabic craftsmanship terminology through french, reflects the transmission of specialized woodworking techniques. the core logic of the word has remained remarkably stable, consistently denoting the specifically cut cavity that receives a projecting tenon to create a strong, fixed joint.
Analysis
this word is a loanword from french, where its spelling and form were largely fixed before entering english. it is not productively formed from smaller, recognizable english morphemes.
Examples
the carpenter carefully chiseled out a rectangular mortise in the table leg.
