Late 16th century (as periment): perhaps an alteration of pyramid.

  • pyramid from Late Middle English:

    The word pyramid was first used in English in the geometrical sense. It came via Latin from Greek puramis, which also meant a type of cake. This is taken by some to be the earlier sense, the geometrical sense arising from a resemblance in shape. An Egyptian origin is now generally rejected. Pediment (late 16th century) for the triangular upper part of a building was formerly written as periment and may be an alteration of pyramid.
