What does “amphitheatre” mean?

An oval or circular open-air venue with tiered seating used in the Roman world for gladiatorial contests, beast hunts, and public executions.

Etymology

From Latin amphitheatrum, from Greek amphitheatron, formed from amphi ("on both sides, around") and theatron ("place for viewing"), from theasthai ("to watch"). The name describes a building with seats all around the arena, as if two theatres were joined face to face. The word came into English in the late Middle Ages. Amphitheatre is the British spelling and amphitheater the American one.
