Mortise and tenon A square hole with a square peg. If you look at a wooden table or chair. The leg has the mortise and the side rails have the tenon. The mortise is a rectangular hole slightly smaller than the width and thickness of the rail. On the rail, it extends past the visible length probably about 1 inch. This varies depending on the construction. This extension is between 1/8 to 1/4 of an inch smaller on each side than the rail. It fits into the mortise. Makes for a very strong joint.
Mortise and tenon joints are also used in post and beam homes and timber frame homes. As the most common timber framing joint, the mortise & tenon is versatile and functional. It is used to fasten connectors, posts, collar ties, struts, etc. The tenon can vary in size from 1-1/2" thick by 4" long to 3" thick by 10" long, depending on the load requirements of a particular joint. It is held tight by hardwood pegs.
The tenon saw is a short saw with fine teeth and a stiffener at the top of the blade .It's purpose is to make small very accurate cuts ,as in cutting tenons in a mortice and tenon joint.
A tenon saw is a stiff handsaw used to cut tenons on the end of a bit of wood. It can remove one or two sections of timber leaving a thinner section (a tenon) which is then glued into a mortice (a squared off groove in another bit of wood) making a strong mortice and tenon joint. Framed doors are made this way.

A tenon (also called a back saw or Jack saw) is a rigid back cutting saw used for cutting furniture joinery: tenon joints, housing dados, sliding dovetails, even box and flat finger joints. Tenon saws come in two basic varieties: rip for cutting with the grain, and crosscut for cutting across the grain.
A tenon saw is a short, stiff-bladed tool which is generally used when the cut needs to be straight. Typical applications would be for cutting mitre joints and tenons for mortice and tenon joints - hence the name. It is a fine-toothed rip saw and will generally cut on both the forward and backward strokes.
