What's it all about?
Have you ever wondered why scoring three goals in one game is called a hat-trick, or if players get an actual cap when they play internationally?
These are both examples of jargon - the specialised vocabulary, technical terms or slang used by a profession, trade or group. You might have heard this term in relation to law or medicine, but football has its own jargon.
Well, wonder no more. BBC Bitesize is here to help you learn the origins of some of the best-known and most widely used football terminology - just in time for the 2026 FIFA Men's World Cup!

Hat-trick
A player gets a hat-trick when they score three goals in one game, but the use of the term actually didn’t start on the football pitch.
The phrase came from cricket, and was used when a bowler took three wickets from three consecutive balls. The club would give the bowler a hat to celebrate this achievement.
Nutmeg

If you’ve been nutmegged, you might feel a bit foolish. Some argue this was part of the reason behind using it to describe the ball being threaded between a player’s legs.
In the 1870s, nutmeg - a spice native to Indonesia - was very valuable. Sneaky traders would mix wooden replicas in with the real nutmegs to trick the people who bought them.
Clean sheet

If your team wins without letting the other team score, you’ve kept a clean sheet.
This is because sports reporters used to record scores on white sheets of paper - so if yours was clean at the end of the match, that would mean no goals had been scored against you.
Cap

When a player plays for their country’s team, they’re said to receive a cap.
As it turns out, players literally do get a cap! Years ago, these were used to distinguish teams from one another, before distinctly coloured football shirts became the norm.
The record-holder for England is goalkeeper Peter Shilton, with 125 appearances between 1970 and 1990. Wayne Rooney has 120, while David Beckham is in third place with 115.
Volley

Derby

A derby is when two teams from a local area play against one another.
There are a couple of different theories about the origins of this word. One is that it comes from a horse race called the Epsom Derby, which was started by the 12th Earl of Derby in 1780. Because of its fierce head-to-head combat, the word came to mean any highly competitive sporting event.
Others claim it stems from the town of Ashbourne in Derbyshire, which has hosted a no-rules Shrovetide street football match since at least 1687, with the two halves of the town playing against each other. It's still played annually today - though it's a little less dangerous than it used to be!
