πυραμίς

Etymology
Perhaps from Ancient Greek, from + , or from , from  +  +. 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 and that of πυραμίς. It is also possible that the ‘monument’ sense and the ‘cake’ sense were originally etymologically distinct but came to be identical due to.
