stadium
Synonym discussion
Sense: noun/1
A stadium and an arena both hold large crowds for events, but an arena is usually indoors (e.g. a basketball arena), while a stadium is typically open above or has a partially covered roof. A field is the playing surface itself, not the structure around it — players run onto the field, but fans watch from the stadium seats. Venue is a much broader term that covers any event location, from a small hall to a huge outdoor space. Ground (chiefly British) can mean a sports field with some seating, like a cricket ground or football ground. For example: 'Fans filled the stadium to watch the players run onto the field.'

Etymology
The word stadium comes from Latin 'stadium', borrowed from Ancient Greek 'stadion' (στάδιον). In ancient Greece, a stadion was a unit of distance equal to about 185 metres — the length of a standard footrace. Over time the word came to refer to the racecourse itself, and later to any large building or grounds with tiers of seats for spectators.
