Whether you’re new to tennis or you’ve been watching the sport for years, you’ve probably come across some tennis phrases and terminology that aren’t used anywhere else.
What exactly is a break point? Why do commentators talk about a bagel? What’s the difference between a volley and a half-volley?
Tennis has developed its own language over more than a century. Some terms describe how the game is scored, others explain different shots, while many have become part of the sport’s unique culture.
This glossary explains the most important tennis terms in plain English. Some are essential for understanding every match, while others are expressions you’ll hear from commentators, coaches and experienced fans.
Use it as a reference whenever you come across an unfamiliar term—or read it from start to finish to become fluent in the language of tennis.
Scoring Terms
Love
Love means zero in tennis scoring.
If neither player has won a point, the score is called love-all. If the server wins the first point, the score becomes 15-love. If the receiver wins it, the score is love-15.
The exact origin of the term isn’t certain, but the most common explanation is that it comes from the French word l’œuf (“the egg”), whose shape resembles the number zero. While historians debate this theory, “love” has been part of tennis vocabulary for centuries and remains one of the sport’s most recognisable expressions.
15, 30, 40
Unlike most sports, tennis doesn’t count points as 1, 2 and 3.
Instead, the progression is:
- 15
- 30
- 40
- Game
Although several theories exist, the most widely accepted explanation links these numbers to early French tennis and the quarters of a clock face. Whatever their exact origin, they have become one of the defining characteristics of the sport.

Deuce
A game reaches deuce when both players have won three points, making the score 40–40.
From deuce, a player must win two consecutive points to win the game. The first point gives them advantage, while the second wins the game. If they lose the next point instead, the score returns to deuce.
Many of the longest and most dramatic games in tennis are played from deuce because neither player wants to give up the advantage.
For a more detailed explanation, read our complete guide to What is Deuce in tennis?
Advantage
After deuce, the player who wins the next point gains advantage.
If they win the following point, they win the game. If they lose it, the score returns to deuce and the battle continues.
Commentators often say “advantage server” or “advantage receiver”, depending on which player is one point away from taking the game.
For a more in-depth explanation, read our guide on, What Does Advantage Mean in Tennis?
Game
A game is won by the first player to win four points, provided they lead by at least two points.
Games are the building blocks of every tennis match. Players combine games to win sets, and sets combine to decide the match.
Set
A set is a collection of games.
Most sets are won by the first player to reach six games with a two-game advantage. If the score reaches 6–6, a tiebreak is usually played to decide the set.
For a complete explanation, see Tennis Sets Explained.
Match
A match is won by winning the required number of sets.
Most professional matches are played as best of three sets, while men’s singles at Grand Slam tournaments are played as best of five sets.
Understanding the difference between games, sets and matches is one of the first steps to understanding tennis.
Break Point
A break point occurs when the receiving player needs just one more point to win the game on their opponent’s serve.
Because holding serve is such an important part of tennis, break points are often the most pressure-filled moments in a match.
Our full guide to ‘What is a Break of Serve in Tennis’ explores this in much greater detail.
Set Point
A set point is any point that gives a player the opportunity to win the current set.
For example, if a player leads 5–4 and 40–15, they have two set points.
Winning either point ends the set immediately.
Match Point
A match point is any point that would win the entire match.
These are often the most memorable points in tennis, as they determine the final result.
A player may have one match point—or several—depending on the score.
Tiebreak
A tiebreak is a special game played when a set reaches 6–6 in most competitions.
Instead of traditional scoring (15, 30, 40), players count points numerically. The first player to reach seven points with a two-point advantage wins the tiebreak and the set.

Hold of Serve
A player holds serve when they win a game in which they were serving.
At the professional level, holding serve consistently is one of the most important factors in winning matches.
A player who serves well puts constant pressure on their opponent to do the same.
Serving Terms
Ace
An ace is a serve that lands legally inside the service box and is not touched by the receiver.
Because the receiver never makes contact with the ball, the server wins the point immediately.
Aces are one of the clearest indicators of a powerful and accurate serve. Players with big serves often finish matches with double-digit ace counts, while others rely more on placement and spin than outright speed.
Although an ace is the ideal outcome from a serve, consistently landing first serves and avoiding double faults is usually more important over the course of an entire match.
Double Fault
A double fault occurs when a player misses both their first and second serve.
Because every server is allowed two attempts to begin a point, failing on both immediately awards the point to the receiver.
Double faults often happen when players become too aggressive on their second serve or tighten up under pressure. Even the world’s best players occasionally produce double faults at crucial moments.
Reducing double faults is one of the quickest ways recreational players can improve their results.
Fault
A fault is any serve that fails to start the point legally.
Common reasons include:
- the serve lands outside the correct service box
- the ball hits the net and does not land in the correct service box
- the server commits a foot fault
- the server misses the ball completely while attempting to serve
One fault is simply a second chance. Two faults in a row become a double fault.
Foot Fault
A foot fault occurs when the server touches or crosses the baseline before striking the ball.
The server must remain behind the baseline until the moment they make contact with the serve.
Foot faults are relatively uncommon at the professional level but are more frequent among beginners, who often step into the court too early.
Like any other faulty serve, a foot fault counts as one of the server’s two attempts.
First Serve
The first serve is a player’s initial attempt to begin the point.
Because there is still a second serve available if it misses, players often hit their first serve with greater speed and aggression.
A high first-serve percentage is one of the strongest indicators of serving consistency.
Second Serve
If the first serve is a fault, the server gets a second serve.
Unlike the first serve, the second serve carries much greater risk because another fault immediately loses the point.
For this reason, players usually hit second serves with more topspin and margin for error rather than maximum power.
At higher levels, a reliable second serve is often just as valuable as a powerful first serve.
Service Winner
A service winner is a serve that the receiver touches but cannot return successfully.
Unlike an ace, the ball does make contact with the opponent’s racquet.
Service winners are common when a serve is hit with enough pace, spin or placement to force a weak return that never comes back into play.
Flat Serve
A flat serve is struck with minimal spin.
It travels quickly through the air and is capable of producing the fastest serve speeds in tennis.
The trade-off is that flat serves offer less margin for error, making them harder to land consistently than spin serves.
Many players use flat serves down the middle on first serves when trying to hit an ace or force a weak return.
Slice Serve
A slice serve is hit with sidespin, causing the ball to curve through the air and skid sideways after bouncing.
Right-handed players often use a slice serve wide on the deuce court to pull their opponent off the court, creating space for the next shot.
While usually slower than a flat serve, the movement of a slice serve can make it much more difficult to return.
Kick Serve
A kick serve is struck with heavy topspin.
Instead of skidding low after the bounce, it jumps high, making it difficult for the receiver to attack aggressively.
Kick serves are especially common as second serves because the topspin helps bring the ball safely into the service box while still creating problems for the opponent.
Although they are generally slower than flat serves, kick serves are among the most reliable deliveries in tennis.
Shot Types
Forehand
A forehand is a shot played from the dominant side of the body.
For a right-handed player, the forehand is struck on the right side. For a left-handed player, it is struck on the left.
The forehand is usually the first attacking weapon players develop and is often used to generate power and topspin.
Many professionals build their entire game around a dominant forehand.
Backhand
A backhand is played from the opposite side of the body to the forehand.
Players may use either a one-handed or two-handed backhand, depending on their technique and preference.
Although often considered the more difficult side for beginners, the backhand is capable of producing just as much accuracy and control as the forehand.
Volley
A volley is a shot struck before the ball bounces.
Volleys are usually played close to the net, allowing players to take time away from their opponent and finish points quickly.
Good volleys rely more on positioning and control than on large swings.
Half-Volley
A half-volley is played immediately after the ball bounces, often when it is only a few centimetres above the court.
It is one of the most difficult shots in tennis because players have very little time to react.
Half-volleys are frequently used when approaching the net or recovering from a low, fast shot.
Overhead Smash
An overhead smash is played above the head, usually in response to a lob.
It resembles the serving motion but is struck during a rally.
Because the ball is contacted from a high position, the smash is normally used to finish the point with power.
Lob
A lob is a high shot designed to send the ball over an opponent positioned near the net.
A defensive lob buys time by pushing the opponent backwards, while an attacking lob is intended to win the point outright.
A well-executed lob is one of the most effective passing shots in tennis.
Drop Shot
A drop shot is played softly so that the ball lands just over the net.
Its purpose is to draw the opponent forward, often after they have been pushed deep behind the baseline.
The best drop shots combine disguise with delicate touch.
Passing Shot
A passing shot is hit past an opponent who has moved forward to the net.
It may be struck crosscourt, down the line or occasionally as a lob.
Passing shots are among the most exciting winners in tennis because they require precision under pressure.
Approach Shot
An approach shot is the shot played before moving towards the net.
Rather than trying to hit an outright winner, the goal is to force a defensive reply that can be finished with a volley.
Good approach shots are usually deep and well placed.
Drive Volley
A drive volley is an aggressive volley struck with a longer, more attacking swing than a traditional volley.
Rather than simply blocking the ball back into play, the player attempts to generate pace and finish the point.
Drive volleys are most commonly seen when players move forward to attack a shorter ball.
Topspin
Topspin is forward rotation on the ball.
It causes the ball to dip more quickly after crossing the net and bounce higher after landing.
Because topspin provides greater control while allowing players to hit aggressively, it is the dominant type of spin in modern tennis.
Slice
A slice is backspin applied to the ball.
Instead of bouncing high, sliced shots tend to stay low and skid through the court.
Players use slice for defensive shots, approach shots and to vary the pace and rhythm of rallies.
Court & Positioning
Baseline
The baseline is the line at the back of each side of the court.
Most rallies begin with both players positioned just behind the baseline, where they have the best balance between attacking and defending.
Modern professional tennis is largely played from the baseline, although players regularly move forward to finish points at the net.
Service Box
The service box is one of the four rectangular areas closest to the net.
Every serve must land in the correct diagonal service box to begin the point legally.
Once the serve has landed, players may hit the ball anywhere within the court boundaries.
Alley
The alley is the strip of court between the singles sideline and the doubles sideline.
These areas are only used during doubles matches.
In singles, a ball that lands in the alley is out. In doubles, the same shot is perfectly legal.
Net Cord
The net cord is the white band that runs along the top of the net.
Players often refer to a shot that clips the top of the net and still lands in as a net cord winner.
Although usually accidental, these shots can dramatically change the outcome of a point.
No-Man’s Land
No-man’s land is the area between the service line and the baseline.
Players generally try to avoid standing here because it leaves them vulnerable to both deep groundstrokes and short balls.
There are exceptions—particularly when moving forward to attack—but remaining stationary in no-man’s land is rarely a good tactical choice.
Crosscourt
A crosscourt shot travels diagonally across the court.
Because the court is longer diagonally than it is straight ahead, crosscourt shots provide a larger margin for error and are generally considered the safest direction for sustained rallies.
Most baseline exchanges in professional tennis are played crosscourt.
Down the Line
A down-the-line shot travels almost parallel with the sideline.
It is usually more aggressive than a crosscourt shot because the target area is smaller and the net is slightly higher.
Players often use down-the-line shots to change direction and surprise an opponent.
Inside-Out Forehand
An inside-out forehand is played when a player moves around their backhand to hit a forehand diagonally into the opposite corner.
Many of the world’s best players use this pattern to attack while relying on their strongest shot.
It requires excellent footwork but is one of the most effective tactical plays in tennis.
Match Statistics & Analysis
Rally
A rally is the sequence of shots played after a successful serve until the point ends.
Some rallies last only one or two shots, while others can continue for dozens of strokes.
Long rallies often become defining moments in important matches.
Winner
A winner is a shot that lands in the court and cannot be returned by the opponent.
Unlike an error, the point is won because of the quality of the shot rather than a mistake from the other player.
Power, precision and timing all contribute to hitting winners.
Forced Error
A forced error occurs when a player misses a shot because of pressure created by their opponent.
Examples include returning a powerful serve, chasing a deep groundstroke or attempting to reach a well-placed volley.
Although recorded as an error, the opponent deserves much of the credit.
Unforced Error
An unforced error is a mistake made without significant pressure from the opponent.
Missing a routine forehand or hitting an easy volley into the net are common examples.
Unforced errors are one of the most closely watched statistics in professional tennis because they often reveal which player maintained better consistency.
Rally Length
Rally length refers to the number of shots played in a point after the serve.
Some players thrive in short rallies built around powerful serving and aggressive attacking.
Others prefer longer exchanges, gradually wearing down their opponent through consistency and patience.
Return Winner
A return winner is a serve return that wins the point immediately.
These are relatively rare because serves are designed to put the receiver under pressure.
A clean return winner is often a sign of outstanding anticipation and timing.
Hold
A hold (or hold of serve) occurs when a player wins a game in which they were serving.
Holding serve consistently is a fundamental part of successful tennis, especially on faster court surfaces where breaks of serve are less common.
Break of Serve
A break of serve occurs when the receiving player wins the game.
Because serving generally provides an advantage, breaking serve is often the moment that decides a set.
Players who create frequent break opportunities place constant pressure on their opponents.
Informal & Historic Tennis Terms
Bagel
A bagel describes a set won 6–0.
The name comes from the resemblance between the number zero and the shape of a bagel.
Commentators often say a player “served up a bagel” after winning a set without conceding a game.
Breadstick
A breadstick is a set won 6–1.
Like bagel, it is an informal expression that has become part of tennis culture.
The nickname comes from the resemblance between the number one and a breadstick.
Golden Set
A golden set is one of the rarest achievements in tennis.
It occurs when a player wins a set 6–0 without losing a single point, meaning they win all 24 points in the set.
Only a handful of verified golden sets have ever been recorded in competitive tennis.
Golden Slam
A Golden Slam is achieved by winning all four Grand Slam singles titles and the Olympic gold medal in the same calendar year.
It is one of the rarest accomplishments in sport.
Career Grand Slam
A Career Grand Slam means winning each of the four Grand Slam singles tournaments at least once during a player’s career.
Unlike a Golden Slam, the titles do not need to be won in the same year.
Only a select group of players have completed this achievement.
Lucky Loser
A lucky loser is a player who loses in the final round of qualifying but enters the main draw after another player withdraws before the tournament begins.
Although they technically lost their qualifying match, they receive a second chance because a place becomes available.
Lucky losers have occasionally gone on to make deep runs in major tournaments.
Walkover
A walkover occurs when a player advances because their opponent withdraws before the match starts.
Since no ball is struck, the match is not officially played.
Walkovers are usually the result of illness or injury.
Retirement
A retirement occurs when a player begins a match but cannot continue, usually because of injury or illness.
The opponent is declared the winner, and the match result stands even though it ends early.
Tweener
A tweener is a shot played between a player’s legs.
Although often spectacular, it is usually attempted only when chasing a lob that has travelled behind the player.
Successful tweeners are among the most memorable shots in professional tennis.
Moonball
A moonball is a very high, heavily spun shot that travels deep into the opponent’s court.
Moonballs are often used to disrupt rhythm, force errors or buy time to recover position.
While they may not be the most exciting shots to watch, they can be remarkably effective.
Final thought
Learning tennis terminology isn’t about memorising definitions—it’s about understanding the language of the sport.
The more matches you watch or play, the more familiar these terms become. Before long, phrases like break point, inside-out forehand and kick serve stop sounding technical and start describing exactly what you see happening on court.
That’s one of the pleasures of tennis. The more of its language you understand, the more enjoyable every match becomes.
