How to use pilaster

A pilaster is an architectural element, specifically a flattened column that projects slightly from a wall. It differs from a true column in being integrated into the wall surface rather than free-standing, and is used in both classical and modern architecture primarily in formal or historical contexts. The term is technical but accessible to readers with moderate architectural knowledge.

Common phrases

pilastered (adjective)

A common mistake

Learners sometimes confuse pilasters with pilasters, or use 'pilaster' to refer to any wall-mounted vertical element; technically, a pilaster must have the proportions and classical detailing characteristic of a column.
