Origin and usage
The word pyramid possibly comes from the Egyptian word ‘pimar’, or more likely from the Greek ‘pyramis’. Other forms of the word include the Latin ‘pyramis’ and Old French ‘piramide’. Pyramid was first used in English sometime in the 1550s in the geometrical sense.
Pyramid is a word that usually refers to a three-dimensional shape or structure that has a square base and four flat triangular sides that meet at a point. There are many different kinds of pyramids, but the most famous in the world are the ancient pyramids at Giza in Egypt.
There are three famous ones here known as the Great Pyramids of Giza: Menkaure, Khafre and Khufu. These massive stone structures were built to house the tombs of Egyptian pharaohs, or kings. In ancient Egypt, people believed that natural death was just the beginning of a journey into the afterlife, so pyramids were used as burial crypts so that kings and other important figures could enter the afterlife with all of their wealth and possessions.
One of Giza’s great pyramids, Khufu, was built around 2600 BC and is the only one of the original Seven Wonders of the World that still stands today.
