Which term refers to a vertical wall of masonry units?

• A. Lintel
• B. Facade
• C. Wythe
• D. Panel

Answer: (C)

Wythe is the term for a vertical wall of masonry units. Each wythe forms a continuous vertical layer of bricks or blocks, and a wall can have one or more wythes to reach the desired thickness. When multiple wythes are used, they may be separated by a cavity and tied together, which is common in cavity walls. This terminology helps inspectors describe wall assemblies accurately. Lintel refers to the horizontal piece above openings, facade is the exterior face of the building, and panel is a flat surfaced element, not the vertical masonry wall itself.
