Etymology

Etymology 1

From French pyramide, from Old French piramide, from Latin pȳramis, pȳramidis, from Ancient Greek πῡραμίς (pūramís), possibly from πῡρός (pūrós, “wheat”) + ἀμάω (amáō, “reap”) or from Egyptian pr-m-ws (“height of a pyramid”), from pr (“(one that) comes forth”) + m (“from”) + ws (“height”). Schenkel and K. Lang proposed hypothetical Coptic *ⲡⲓⲣⲁⲙ (*piram) or *ⲫⲣⲁⲙ (*phram) derived from Egyptian mr via metathesis as a source of πῡραμίς (pūramís) while Schenkel also suggested it being the source of Arabic هَرَم (haram) although the latter is considered far-fetched by Takacs.
