Pediment vs. Gable — What's the Difference?

A pediment is an architectural element found particularly in Classical, Neoclassical and Baroque architecture, and its derivatives, consisting of a gable, usually of a triangular shape, placed above the horizontal structure of the lintel, or entablature, if supported by columns. The tympanum, the triangular area within the pediment, is often decorated with relief sculpture.

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.
