1. A vertical surface commonly situated at the end of a building, usually adjoining a pitched roof; its shape depends on the type of roof and parapet, although most often it is triangular; often extends from the level of the cornice up to the ridge of the roof. If the gable is on the façade rather than the back end, the building is said to be front-gabled.
2. A similar end that is not triangular in shape; for example, a gambrel end (US).
