Perhaps from Ancient Greek πυραμός (puramós) + -ῐ́ς (-ís), from πυρός (purós, “wheat”) + ἀμάω (amáō, “reap”), or from Egyptian pr-m-ws (“height of a pyramid”), from prj (“(one that) comes forth”) + m (“from”) + ws (“height?”). If the ‘cake’ sense of the word is primary and was later applied to the Egyptian monuments from their resemblance in shape, then the Greek etymology is probable; however, the shape of the cake is unknown, and the ‘monument’ sense is attested a century earlier than the ‘cake’ sense, so that the Greek derivation is problematic. The Egyptian derivation is also problematic in that there is a gap of 1100 years between the attestation of pr-m-ws and that of πυραμίς.
