Origin & History of “pyramid”

Egypt seems a likely ultimate source for pyramid, but its earliest known ancestor is Greek puramís, which passed into English via Latin pyramis. Pediment ‘triangular gable’ (17th c.) probably originated as a garbling of pyramid, later influenced by ped-, the stem of Latin pēs ‘foot’.
