Etymology: "Pyramidal" is a plain formation: "pyramid" with the adjective-forming suffix "-al," which English took from Latin "-alis." The base word "pyramid" came into Middle English from Latin "pyramis," and the adjective followed the same route, arriving in Middle English as "piramidal" and "piramydale," drawn from Medieval Latin "pyramidalis." The word's meaning follows its shape. Something pyramidal is built like a pyramid, with a broad base rising to a narrow apex, so the sense is simply a steep taper toward a point. The same shape gave English words for other things, such as the pyramidal shape of certain bones and crystals, where the term describes form rather than any connection to Egypt.

Synonyms: triangular, cone-shaped
