Hopper - A container that holds large quantities of tennis balls.

In - Descriptive of a good shot that lands in the opponent's court.

Let - A stroke that doesn't count and must be replayed. This most commonly happens when a serve touches the net before entering the proper service court. It's also a let if the serve is delivered before the receiver is ready, if play is interrupted by some unusual occurrence (such as an animal running onto the court), or if a linesman's decision that resulted in stoppage of play is reversed by the umpire.

Lob - A shot that is hit in a high arc, usually over the opponent's head. See defensive lob; offensive lob.

Long - Descriptive of a shot that is out because it hits the court beyond the opponent's baseline.

Love - Zero; no points. For example, a score of 40-love means that the server has scored three points and the receiver hasn't scored any. In a set score, it means that the player hasn't won any games. Probably derived from the old French word for egg, l'ove, because a zero is egg-shaped.

Open racket - A racket held with an open grip.

Out - Descriptive of a shot that lands outside the playing area, wide and/or long.

Poach - In doubles, to hit a ball, usually with a volley, that would ordinarily have been played by the partner.

Racket - The instrument that's used to hit the ball. It has a long, straight handle and an oval frame strung with natural gut or a synthetic material. Up until the late 1960s, rackets were made of wood, but then steel and aluminum frames were introduced, followed by frames of graphite, fiberglass, titanium, and carbon. Maximum dimensions are 29 inches in overall length, 12 inches in overall width. The hitting surface can be no more than 15 inches long and 11 inches wide. Also spelled racquet.

Return - To hit an opponent's shot back over the net and in play. After service, every successful shot is a return.

Round robin - A tournament in which each player meets every other player and final standings are determined by the won-lost records. Such a tournament is sometimes a preliminary round to determine seedings and order of play.

Seed - Before a tournament, certain players are ranked, based on their ability and recent performances. The process is called seeding, the rankings are called seeds, and the top-ranked player is called the top seed. Matches are then arranged so that the top-seeded players will not meet until the later rounds of the tournament.

Serve - The shot that begin each point. Standing behind the baseline, the player must toss the ball into the air and hit it into the diagonally opposite service court. The server is given two chances to make a valid serve. A failure is called a fault and a double fault results in loss of the point. On the first point, the server must be to the right of the center line, and then alternates sides with each point. In singles, the players alternate service throughout a match. In doubles, service alternates between the sides, and all four players serve in turn.

Serve and volley - A style of play in which the server takes the net after each successful serve in order to volley the opponent's return.

Server - The player whose turn it is to serve.

Service - See serve.

Set - A set is a group of games that is won by the player or side that first wins at least six games with a two-game margin, unless a tie-breaker is employed. In major tournaments, there are usually five sets in a men's match and three in a women's match. See scoring system; tie-breaker.

Set point - A point that, if won by the leader, will result in winning the set. See also game point; match point.

Sudden death - A tie-breaker of predetermined length. The most commonly used are the 9-point tie-breaker, in which the first player to score 5 points is the winner, and the 13-point tie-breaker, which is won by the first player to score 7 points.

Sweet spot - The optimum hitting area, around the middle of the racket face.

T - The midcourt area, where the service lines meet the center service line.

Thirty - The second point scored by a player or side in a game. See point; scoring system.

Topspin - Forward spin, around the ball's horizontal axis, that's applied by drawing the racket strings up and over the ball at the moment of impact. A shot hit with topspin is more likely to stay in play, because it drops sharply after reaching its highest point, and it takes a high bounce.

Two-handed backhand - A backhand shot on which the player has both hands on the racket handle.

Unforced error - Loss of a point caused by a poorly hit shot that goes into the net or out of the court. Compare forced error.
