A player is a person who participates in a game, sport, or other activity.
This individual might be competing against others or working as part of a team toward a common goal. Beyond competitive contexts, a player can also refer to someone engaging in a musical instrument, a recording of audio or video, or even an actor in a dramatic performance.
In broader use, a player could be someone acting in a specific role, or manipulating a situation to their advantage.
