How to use pediment

Pediment is a technical architectural term referring to the triangular gabled section above a portico or between a pitched roof and the wall face, commonly found in classical and neoclassical buildings. In geology, it describes a specific landform found at mountain bases in arid or semi-arid regions. The architectural sense is more widely known in general English.

A common mistake

Learners sometimes confuse pediment with parapet; a pediment is specifically triangular and sits above the roofline, while a parapet is a low wall at the edge of a roof or terrace.
