Simplified etymology

Pyramid entered late Middle English through Latin from Greek puramis and was first used in English as a geometrical term. The Greek word also denoted a kind of cake, and some scholars consider that the earlier sense, with the geometrical meaning arising from resemblance of shape; an Egyptian origin is now generally rejected.

Through French and Latin pyramis from Ancient Greek pyramis, "pyramid." The Greek word's deeper origin is uncertain; proposed Egyptian and Greek derivations remain disputed. Figurative uses preserve the structure's broad base and narrowing summit.
