What is another word for spandril?
Pronunciation: [spˈandɹə͡l] (IPA) 
Spandril refers to the triangular shape that appears between the top of an arch and a straight line above it. Some of the synonyms for spandril include spandrel, space filler, triangular panel, and lunette. Most of these words have been derived from the architectural elements of old buildings and bridges. A spandrel can either be an open or closed space, depending on the intention of the architect. It can be ornately decorated, or left plain. Regardless of its design, the spandril always complements the arch it falls under. When it comes to creating an arc on a building, the design of the spandril is just as important as the arch itself.
