|Mortice:||Slot or recess cut into a timber to receive a tenon.|
|Mortice & Tenon Joint:||A joint fundamental to the carpentry of the Middle Ages, used to connect two timbers meeting perpendicularly or obliquely. The tenon is inserted into the mortice and then the joint is pegged. The joint works well in compression, but is poor in tension. Various types were developed; see below:|

|Purlin:||Longitudinal roof timber supporting common rafters, usually set in the plane of the roof; framed into the principal rafters, and/or set into a masonry gable (see above and Fig. b).
