Sense: noun/1

All four name places where crowds gather to watch something, but they differ in shape, size, and use. An amphitheater is round or oval with seats rising in steps around a central space, and it is closely tied to ancient and open-air performances such as plays or contests. An arena stresses the flat central area where the action happens; modern arenas are often roofed and used for concerts or indoor sport. A stadium is much larger and built mainly for outdoor ball games, with the field at the centre. A coliseum is a grand round arena and is often used as the actual name of one famous building. So you would watch a summer play in an open amphitheater, a basketball game in an arena, and a football match in a stadium.

Etymology

GreekLatinEnglish

The word comes from Greek roots: 'amphi-' means 'on both sides' or 'around', and 'theatron' means 'a place for watching'. Put together, the idea is a viewing place with seats wrapped all the way around a central space, unlike an ordinary theatre where the audience sits only on one side. Latin borrowed the term as 'amphitheatrum' for the great round arenas of the Roman world, and English took it from there.
