A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches.
The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns.
Gable style is also used in the design of fabric structures, with varying degree sloped roofs, dependent on how much snowfall is expected.
Sharp gable roofs are a characteristic of the Gothic and classical Greek styles of architecture.
A Wimperg, in German and Dutch, is a Gothic ornamental gable with tracery over windows or portals, which were often accompanied by pinnacles.
