A "spectator" is a person who watches an event, performance, or activity without participating in it. Spectators are commonly found at sports events, concerts, theater performances, and other public gatherings. Their role is to observe and enjoy the experience, often cheering or reacting to what they see.
In many cases, spectators contribute to the atmosphere of an event. For example, in sports, the energy and enthusiasm of the crowd can enhance the performance of the athletes. Similarly, in theater, audience reactions can influence the performers, creating a dynamic interaction between the stage and the seats.
