Etymology

Origin of pyramid

First recorded in 1350–1400; from Latin pȳramid- (stem of pȳramis ), from Greek pȳramís; replacing Middle English pyramis, from Latin, as above

Explanation

When you think pyramid, you're probably picturing the famous pyramids of Egypt — the enormous triangular monuments where pharaohs were buried thousands of years ago. Besides being a polyhedron shape, pyramid can also represent shady financial dealings. If you've got a pyramid scheme — and if you do, you may be reading this from your jail cell — you have people buy into your "investment" and then they recruit others to buy in, too. The early investors rise in the pyramid and are then paid "returns" out of the funds paid in by the new investors they've recruited (the pyramid base), and on and on.
