mortise-and-tenon joint
A joint between two wood members that is formed by fitting a tenon at the end of the one member into a mortise in the other member; the mortise and the tenon are usually cut or shaped with a mallet and chisel. After fitting the tenon into the mortise, a hole is drilled through them with an auger; then a wooden peg (treenail) is driven into the hole to secure the joint. Also called a mortise-and-pegged joint.
