A spandril is a term used in architecture to describe the space between the curve of an arch and the rectangular frame that surrounds it.
The artist painted beautiful designs in the spandril above the doorway.
Spandril originates from the Italian word 'spandrel', which refers to the space between the outer curve of an arch and the rectangular framework that surrounds it. The term is derived from the Latin 'spandere', meaning to spread out or extend. Thus, a spandril is the area that spreads out between the arch and the surrounding structure.
Imagine the space that 'spreads out' between an arch and its frame — that's what a spandril represents.
