Offside
This is the most argued-over rule in sports, but the basic idea is simple. Think of it as an anti-cherry-picking rule. An attacking player cannot be closer to the opponent's goal than both the ball and the second-to-last defender when the ball is passed
to them. Basically, you can't just have your fastest player hang out by the goalie waiting for a long pass. It’s not an offense just to be in an offside position, but it is if you become involved in the play.
Stoppage Time (or Added Time)
You'll see this at the end of each 45-minute half. The game clock in soccer never stops, so the referee adds time back to compensate for delays like injuries, substitutions, or goal celebrations. This is why a half that's supposed to be 45 minutes might end at 48 or 50 minutes. The fourth official holds up a board showing the minimum number of minutes to be added.
VAR (Video Assistant Referee)
This is soccer's version of instant replay. A team of officials watches the game remotely with access to dozens of camera angles. They automatically review four game-changing situations: goals (and any fouls leading up to them), penalty decisions, direct red card incidents, and cases of mistaken identity for a card. They can alert the on-field referee to a "clear and obvious error," who can then review the play on a sideline monitor and make the final call.
Set Piece
This is a catch-all term for any time the game is restarted with a stationary ball. The most common examples are free kicks (awarded after a foul), corner kicks (awarded to the attacking team when the defense kicks the ball over their own goal line), and penalty kicks. These are crucial scoring opportunities because they allow teams to organize a specific play while the defense scrambles to set up.
Yellow Card vs. Red Card
Think of these like escalating warnings. A yellow card is a formal caution for unsporting behavior, a reckless foul, or persistent rule-breaking. A player who receives two yellow cards in the same match is then shown a red card. A red card means immediate ejection from the game, and the player's team must play the rest of the match a man down. A straight red can also be given for serious offenses like violent conduct or denying an obvious goal-scoring opportunity illegally.
The Group Stage
This is the first phase of the World Cup. For 2026, the 48 teams are split into 12 groups of four. In this round-robin stage, every team plays the other three teams in its group once. Teams get three points for a win, one for a draw, and zero for a loss. The top two teams from each group, plus the eight best third-place teams, advance to the next phase.
The Knockout Round
This is where the real drama begins. Starting with the new-for-2026 "Round of 32," the tournament becomes a single-elimination bracket. If you lose, you go home. There are no more draws. If a match is tied after 90 minutes and stoppage time, it goes to extra time. This is where every goal feels massive and the pressure is immense.
Extra Time vs. Penalty Shootout
These are the tie-breakers used only in the knockout rounds. If a match is tied after 90 minutes, the teams play two additional 15-minute periods of "extra time." If the score is still tied after those 30 minutes, the game is decided by a penalty shootout. Each team selects five players to take one-on-one shots against the opposing goalkeeper from the penalty spot. If it's still tied after five kicks each, it goes to sudden death rounds until a winner is decided.
A Nutmeg
This is a bit of slang, but you'll hear it constantly. A "nutmeg" is when a player with the ball cheekily kicks it through an opponent's open legs and collects it on the other side. It's a skillful and slightly embarrassing move for the defender, and it always gets a huge reaction from the crowd.
