Meaning and Definition
A structural, usually wedge-shaped, arch built into a wall above an opening (like a door or window) to redirect weight onto the adjacent piers or columns, relieving pressure on the lintel or opening below.
In broader contexts, the term can be applied to any relieving arch used in construction. In a non-literal, conceptual sense, it can metaphorically describe a system or process that safely redirects pressure or excess.
