The word "pyramid" comes from Greek pyramis (plural pyramides), likely borrowed from an unknown pre-Greek language. The Greek term originally referred to Egyptian pyramids but also to wheat cakes shaped like pyramids. The false breakdown into "pyr" (fire) and "amid" (middle) arose later, influenced by Greek words but not reflecting the true etymology. The geometric and hierarchical meanings developed metaphorically from the structure's shape.
