Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players each, who almost exclusively use their feet to propel a ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed goal defended by the opposing team. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is the world's most popular sport.
Offside is one of the laws in association football, codified in Law 11 of the Laws of the Game. The law states that a player is in an offside position if any of their body parts, except the hands and arms, are in the opponents' half of the pitch, and closer to the opponents' goal line than both the ball and the second-last opponent.
A referee is an official, in a variety of sports and competition, responsible for enforcing the rules of the sport, including sportsmanship decisions such as ejection. The official tasked with this job may be known by a variety of other titles depending on the sport, including umpire, judge, arbiter (chess), commissaire, or technical official. Referees may be assisted by umpires, linesmen, timekeepers, touch judges, or video assistant referees.
In association football, the referee is the person responsible for interpreting and enforcing the Laws of the Game during a match. The referee is the final decision-making authority on all facts connected with play, and is the match official with the authority to start and stop play and impose disciplinary action against players and coaches during a match.
The Laws of the Game are the codified rules of association football. The laws mention the number of players a team should have, the game length, the size of the field and ball, the type and nature of fouls that referees may penalise, the offside law, and many other laws that define the sport. During a match, it is the task of the referee to interpret and enforce the Laws of the Game.
In various sports, a professional foul is a deliberate act of foul play intended to bring about an advantage for the perpetrator's team. Professional fouls are usually committed to prevent an opponent from scoring.

A football pitch is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces are allowed only to be green in colour.
In association football, a substitute is a player who is brought on to the pitch during a match in exchange for an existing player. Substitutions are generally made to replace a player who has become tired or injured, or who is performing poorly, or for tactical reasons. A player who has been substituted during a match takes no further part in the game, in games played under the standard International Football Association Board Laws of the Game.
In the sport of association football, fouls and misconduct are acts committed by players which are deemed by the referee to be unfair and are subsequently penalised. An offence may be a foul, misconduct or both depending on the nature of the offence and the circumstances in which it occurs. Fouls and misconduct are addressed in Law 12 of the Laws of the Game. A foul is an unfair act by a player, deemed by the referee to contravene the game's laws, that interferes with the active play of the match. Fouls are punished by the award of a free kick to the opposing team. A list of specific offences that can be fouls are detailed in Law 12 of the Laws of the Game ; these mostly concern unnecessarily aggressive physical play and the offence of handling the ball. An infringement is classified as a foul when it meets all the following conditions:
- It is committed by a player ;
- It occurs on the field of play;
- It occurs while the ball is in play;
- It is committed against an opponent.

Penalty cards are used in many sports as a means of warning, reprimanding or penalising a player, coach or team official. Penalty cards are most commonly used by referees or umpires to indicate that a player has committed an offence. The official will hold the card above their head while looking or pointing toward the player who has committed the offence. This action makes the decision clear to all players, as well as spectators and other officials in a manner that is language-neutral. The colour or shape of the card used by the official indicates the type or seriousness of the offence and the level of punishment that is to be applied. Yellow and red cards are the most common, typically indicating, respectively, cautions and dismissals.

In association football, goal-line technology is the use of electronic aid to determine if a goal has been scored or not. In detail, it is a method used to determine when the ball has completely crossed the goal line in between the goal-posts and underneath the crossbar with the assistance of electronic devices and at the same time assisting the referee in awarding a goal or not. The objective of goal-line technology (GLT) is not to replace the role of the officials, but rather to support them in their decision-making. The GLT must provide a clear indication as to whether the ball has fully crossed the line, and this information will serve to assist the referee in making their final decision.
