Definition for MOR'TISE

MOR'TISE, n. [mor'tis; Fr. mortaise; Arm. mortez; Sp. mortaja; Ir. mortis. The Armoric mortez signifies both a mortar and a mortise, and the Spanish mortaja signifies a mortise and a winding sheet or shroud. In the latter sense the Portuguese use mortalha, from mortal. These alliances indicate that these words are all from the root of mors, death, which may be from beating or throwing down.]
