Tennis glossary for ATP, WTA and Grand Slam fans
Tennis can be confusing when match pages, TV schedules and live scoreboards use shorthand without explanation. This glossary gives simple definitions for the terms that appear most often when following matches, checking draws, reading rankings or looking for legal streams.
Scoring
Advantage
The point after deuce. If the server wins it, the score is advantage server; if the returner wins it, it is advantage receiver.
Break point
A point where the returner can win the game on the opponent's serve. Break points are often the most important moments in a set.
Deuce
A game score of 40-40. From deuce, a player usually needs two consecutive points to win the game.
Double fault
Two missed serves in a row. The server loses the point immediately after a double fault.
Hold
When the server wins their service game. Strong servers build pressure by holding comfortably and forcing the opponent to serve under scoreboard pressure.
Tiebreak
A special game used to decide a set when the score reaches a specified level, usually 6-6. Players count points normally: 1, 2, 3 and so on.
Tournaments
Grand Slam
One of the four biggest tennis tournaments: Australian Open, Roland Garros, Wimbledon and US Open.
Masters 1000
A top ATP tournament category below the Grand Slams. The name reflects the maximum ranking points awarded to the singles champion.
WTA 1000
A top WTA tournament category below the Grand Slams, used for major women's tour events across the season.
Draws
Seed
A highly ranked player placed in the draw so that top players are less likely to meet in the earliest rounds.
Qualifier
A player who earns a main-draw place by winning matches in the qualifying event before the tournament begins.
Lucky loser
A player who loses in qualifying but enters the main draw because another player withdraws before playing.
Rankings
Protected ranking
A ranking mechanism that may help eligible players enter tournaments after a long injury absence, without treating it as their current ranking level.
Ranking points
Points earned from tournament results. They determine ATP and WTA rankings and usually drop after the relevant results age out of the ranking window.
Surfaces
Hard court
A common tennis surface used at many tour events and two Grand Slams. It usually produces a medium bounce compared with clay and grass.
Clay court
A slower surface where rallies often last longer and movement skills become especially important. Roland Garros is the best-known clay Grand Slam.
Grass court
A faster, lower-bouncing surface associated most strongly with Wimbledon. Grass can reward serving, returning and quick first-strike tennis.
Schedule
Order of play
The official daily match schedule for a tournament, usually showing courts, match order and approximate start structure.
Walkover
A match that is not played because one player withdraws before it starts. It is different from a retirement after the match has begun.
Streaming
Geo-restriction
A viewing limitation based on country or region. Tennis broadcasting rights can differ significantly by location.
Official broadcaster
