Which Law defines the "Offside" rule?

The "Offside" rule is defined in Law 11 of the Laws of the Game. This law outlines the conditions under which a player is considered to be in an offside position and the subsequent implications of being offside during active play. Understanding this law is crucial for referees, as it involves recognizing the position of players relative to the ball and the opponents at the moment when the ball is played to them. Proper application of Law 11 ensures fair play and helps maintain the flow of the game, as it prevents players from gaining an unfair advantage by lingering near the opponent's goal. This makes Law 11 fundamental for both referees and players in understanding game dynamics.
