• piramis (obsolete)

From French pyramide ← Old French piramide ← Latin pyramis ← Ancient Greek πυραμίς (puramis), possibly from a corruption of an Ancient Egyptian phrase or expression (a tentative suggestion: pri-n-mr, "go to the pyramid?", maybe a question asked of ancient Greek tourists), OR from Ancient Egyptian Pir E Mit, "Division of Ten" or "Division of Number" or "Division of Perfection".

The Ancient Egyptian word for pyramid is mr.
