The term 'PART DOVETAIL' is a type of woodworking joint. It is composed of two parts, the TENON and the mortise. The TENON is a rectangular piece of wood that fits into a mortise, which is a hole cut into another piece of wood. The two pieces are then joined together with glue or nails. The TENON is usually the longer part of the joint and is designed to fit snugly into the mortise. The dovetailed joint is strong and durable, making it ideal for furniture construction.
