Refereeing is the process of overseeing a sports game to ensure that the rules are followed. Referees, also known as officials, make decisions on fouls, penalties, and other game-related issues. They help maintain fair play and safety for all participants, ensuring that the game runs smoothly. In many sports, such as soccer, basketball, and football, referees have specific signals and gestures to communicate their decisions to players and spectators. They often work in teams, with each official responsible for different areas of the field or court, allowing for better monitoring of the game.
