armoire (n.)

"large wardrobe with doors and shelves," 1570s, from French armoire, from Old French armarie "cupboard, bookcase, reliquary" (12c., Modern French armoire), from Latin armarium "closet, chest, place for implements or tools," from arma "gear, tools, ship's tackle, weapons of war" (see arm (n.2)). The French word was borrowed earlier as ambry (late 14c.).
