Etymology

Origin of amphitheater

First recorded in 1540–50; from Latin amphitheātrum, from Greek amphithéātron; see amphi-, theater

Explanation

The "amphi" of amphitheater means "on both sides" in Greek. Ancient amphitheaters were exactly as described: open-air theaters that allowed spectators to sit on both sides of the action. Today, the word amphitheater is used to mean any large, semicircular theater space. Often, although not always, they are outdoor spaces where concerts, theater, and other performances can be held. The Hollywood Bowl is an example of a modern amphitheater, where groups like Monty Python and the Beatles have performed. An amphitheater is also a large gallery overlooking an operating room in a hospital — usually used for teaching purposes.
