Terms

Terms people actually search for first.

Antenna

A red-and-white striped rod mounted on each sideline edge of the net, extending 32 inches above it. The ball must cross between the two antennas; passing outside them or touching one is an immediate fault, including when playing a ball back from outside the court.

Attack line

The line 10 feet from the net dividing the court into front row and back row, also called the 3-meter line. A back-row player cannot attack a ball that is entirely above net height in front of this line, and must take off from behind it for the attack to count as legal; only the takeoff point matters, so landing in front of the line is fine.

Back-row attack

An attack by a back-row player who takes off from behind the attack line, also called a back attack. Only the takeoff point needs to be behind the line; landing in front is allowed. This rule lets a team maintain a three-pronged attack even in rotations with only two front-row hitters. A back-row attack through the center of the court is specifically called a pipe.

Block

Reaching hands over the net at the front row to stop an opponent's attack. A block doesn't count toward a team's three allowed touches, so the blocker can immediately play the next ball. Reaching over the net is legal only after the opponent has completed their attack. Back-row players and the libero cannot block, and blocking a serve is not allowed.

Deuce

A situation where the score ties just before the target score, such as 24-24, extending the set until one team leads by two points. Volleyball has no scoring cap, so scores like 28-26 or even 32-30 genuinely occur. In this situation, many teams switch from an aggressive jump serve to a safer float serve, since a single service error hands over the set; others go for broke and target the opponent's weakest receiver.

Dig

A defensive play that keeps an opponent's spike or hard-driven attack from hitting the floor. The standard technique uses the forearms pressed together to form a platform, but a one-handed dig, a foot dig or a full dive are all legal. A pancake, sliding a hand flat on the floor to pop the ball back up, also counts as a dig. Liberos and outside hitters handle the most digs, and a strong dig is what lets defense flip immediately into a counterattack.

Double contact

A fault where a single player touches the ball twice in one action, or where both hands make separate contact and send the ball off in an obvious spin. Often called a double hit, it's called most often during a set. It's an exception on a team's first contact, meaning a hard serve or spike being dug, where two touches within a single action are allowed, so the same-looking play can be ruled differently depending on when it happens.

Dump

A surprise attack where the setter fakes a normal set and instead drops the ball into an open spot on the opponent's court. Only a front-row setter can attempt this freely above net height; a back-row setter faces the same restriction as any other back-row player and can't play a ball fully above net height in front of the attack line. It's most effective when blockers are focused entirely on the hitters and leave the area in front of the setter open, and even one or two successful dumps in a set keeps the opposing block honest.

Float serve

A serve struck with almost no spin, using a short, punching contact on one point of the ball to make it wobble unpredictably in the air. It travels slower than a jump serve but its late, erratic movement makes it hard to receive cleanly. There's a standing version and a jump float, approached and struck in the air; because the error rate is lower, it's usually the best next serve for a beginner to learn after the underhand serve.

Hitting percentage

The rate of kills relative to attack attempts, shown constantly on broadcasts and stat sheets. International stats often pair it with attack efficiency, which subtracts blocked or errored attempts; a high hitting percentage with low efficiency signals a decisive hitter who also makes frequent errors. Middle blockers, who attack from close range with little resistance, typically post the highest marks, while outside hitters, who absorb the difficult high-set attacks, normally post lower ones.

Holding

A fault where a player momentarily catches, cradles or throws the ball rather than cleanly rebounding it off contact, also called a lift or catch. The ball must always be hit rather than held, even briefly. It happens most often on a low ball played overhand, and referees are notoriously inconsistent on where the line falls, so it's common for recreational players to agree on a shared standard before a match starts.

Jump serve

A serve where the player tosses the ball forward, approaches like a spike, and strikes it hard in the air. Top men's players exceed 75 mph, and a strong jump serve alone can disrupt an opponent's entire offensive structure. Because the error risk is high, many players switch to a spinless jump float in close situations. The approach steps are the same as for spiking, so learning them together is efficient.

Libero

A specialist defensive player, wearing a different colored jersey, dedicated to back-row defense and serve receive; introduced into the international rules in 1998. Substitutions involving the libero don't count against a team's substitution limit, letting them enter and exit freely with back-row players, but in exchange the libero can't serve, block, or attack a ball fully above net height. It's essentially the only position where a shorter player can reach the highest level of the sport, and it's a chronically hard position to fill in recreational clubs as well.

Middle blocker

A player who moves along the net to block opposing attacks and hits quick attacks on offense, also called a center. This position moves side to side more than any other, so foot speed matters as much as height, and the tallest player on a team usually fills this role. Middle blockers are typically substituted out for the libero when rotating to the back row, so they spend only about three rotations on court per cycle.

Net touch

A fault called when a player touches the net while playing the ball, resulting in a point and serve for the opposing team. Since a 2013 rule update, incidental contact unrelated to the play is generally allowed, but brushing the white tape along the top of the net during a spike or block attempt is still a fault. It's frequently decided by a matter of millimeters at the fingertips, making it one of the most commonly challenged calls.

Nine-a-side volleyball

A format played with nine players per side, long the dominant recreational format in Korea and Japan. There's no rotation, so positions stay fixed, and the net is often set lower than in six-a-side play, letting players with less jumping ability participate. With more bodies packed onto the court, each player covers a smaller defensive zone and rallies tend to run longer. Corporate sports days and municipal tournaments in some countries still commonly use this format, so it's worth confirming which format a group plays before joining.

One touch

A ball that grazes a blocker's hand, however lightly. Even a graze doesn't count toward the blocking team's three allowed touches, so they still have three more available, and the deflection slows the ball down enough to make the ensuing dig much easier. From the attacking side, since a ball that goes out of bounds after touching the block counts as the attacker's point, hitters sometimes deliberately aim for the block's fingertips in a tactic called a touch-out.

Open attack

The most basic attack, hitting a high set near either sideline antenna. Because the ball hangs in the air longer, opposing blockers have time to set up two or three at a time, but it's also the reliable fallback when the receive breaks down and a clean set isn't available. Most points in recreational play come from here, and it's the play that most honestly reveals an outside hitter's fundamentals.

Opposite

The position lined up diagonally across from the setter, usually attacking near the right-side antenna. Carrying almost no serve-receive responsibility, this player focuses purely on attacking, including from the back row. It's often the team's strongest hitter and fills the offensive gap in rotations where the setter is in the front row and takes up a hitting spot. It's also considered a favorable position for left-handed players.

Outside hitter

The position attacking near the left-side antenna while also carrying serve-receive and back-row defensive duties. This is the busiest role on the team. Since this player usually ends up handling the high, forced open attack whenever the receive breaks down, it's normal for an outside hitter's hitting percentage to look modest even while their share of total team attacks is the highest on the roster.

Over-net fault

A fault for touching the ball in the space over the net on the opponent's side. It's called if a player reaches over and plays the ball before the opponent has completed their three contacts. However, reaching over the net to block is legal once the opponent has finished attacking, and a ball hovering directly above the net can legally be touched by either side simultaneously. The line here is subtle enough that it's the most frequently disputed call in recreational matches.

Overlap fault

A positional fault called if the six players aren't standing in the correct rotational order relative to each other at the moment the server contacts the ball. It occurs if a back-row player stands closer to the net than the front-row player directly in front of them, or if two players in the same row swap left-right order. Once the serve leaves the server's hand, players can move anywhere, so teams typically hold the minimum legal position just long enough to satisfy the rule before scattering to their real spots.

Pipe

A back-row attack launched from the center of the court, typically from the middle-back position. If all the attacks come only from the two sideline antennas, opposing blockers can track them easily; adding this attack through the middle forces blockers to split their attention. It's one of modern volleyball's most relied-upon weapons, since it restores a third attacking option in rotations where the setter is in the front row and only two front-row hitters remain.

Quick attack

A fast attack where the middle blocker strikes the ball almost simultaneously with the setter's release, timed to deny the opposing blocker any time to react. Depending on the height and location of the set, it's sometimes broken into subtypes like an A-quick or B-quick. Even when it doesn't score directly, it's highly effective at pinning the opposing middle blocker to the center, functioning as a decoy that leaves the outside hitters facing only a single blocker.

Rally point system

The scoring method in which the team that wins a rally scores a point regardless of who served, adopted internationally in 1999 to replace the side-out system, under which only the serving team could score. Sets are played to 25 points, the deciding fifth set to 15, always requiring a two-point margin. It made match length predictable, which suited broadcasting, and since every error now directly costs a point, a single service error carries far more weight than it once did.

Rotation

The rule requiring all six players to shift one position clockwise every time their team regains serve; the player in the front-right position rotates back to the back-right position to serve next. Because of this rule, every player cycles through both front-row attacking and back-row defense in turn, and serving out of order is a fault. This is why coaches prepare distinct receive formations and attack combinations for each of the six rotations in advance.

Serve receive

The first contact on an opponent's serve, aimed precisely at the setter, sometimes shortened to just receive. It uses the same flat forearm platform as a dig, and the key feel is creating an angle to rebound the ball rather than hitting it. A receive that lands exactly on the setter opens up every attacking option, including quick attacks and time-difference plays; a shaky one usually forces the team into a single high open attack that the opposing block can read easily.

Service ace

A serve that directly results in a point. This is recorded not only when the receiving team can't touch the ball at all, but also when they touch it but the ball bounces so wildly that they can't return it within three contacts. Because a stronger serve raises both aces and errors together, top teams calculate the risk deliberately, deciding that a couple of extra errors is often worth it for one ace.

Set

The second contact, delivered to place the ball where a hitter can attack it cleanly; the international rules term for what's colloquially called a toss. The standard technique catches the ball briefly above the forehead with all ten fingers before pushing it back out, extending the legs along with the wrists so the ball travels without spin.

Setter

The player who distributes a received ball to the team's hitters, effectively running the offense. Most teams run a 5-1 system, with one setter playing all six rotations, while a 6-2 system, with two setters positioned opposite each other in rotation, is more common at developmental levels or when a team wants three front-row hitters at all times. Hand feel and decision speed matter more than height here, and it's typically the hardest position to fill in a recreational club.

Side-out

Winning a rally that started on an opponent's serve, thereby regaining the serve. Under the rally-point system, this also comes with a point. Elite teams convert side-outs at a very high rate once their receive is stable, so matches at that level are usually decided on break points, points scored while serving. In recreational play too, converting the first side-out is always the immediate goal after conceding a run of points.

Slide attack

An attack where the middle blocker runs behind the setter toward the right side and takes off on one foot to hit, called a slide in English-language broadcasts. The lateral momentum makes it difficult for blockers to track, and it's especially popular in women's volleyball. Because it drags the opposing block's structure sharply to one side depending on where the takeoff happens, it opens up considerably more room for the hitter on the opposite side.

Spike

Jumping to drive the ball hard into the opponent's court, the sport's primary attacking technique. A right-handed hitter typically uses a three-step left-right-left approach, swinging both arms back and then forward to convert that momentum into a jump. The most common beginner mistake isn't a lack of jumping ability but approaching too far under the ball; positioning the ball above and in front of the hitting shoulder is what allows the arm to extend and drive down on it.

Substitute server

A player brought in briefly for the sole purpose of serving. The goal is to disrupt the opponent's receive rhythm with one or two strong jump serves, and the original player is typically swapped back in as soon as the serve is lost. This move is limited by the substitution cap allowed per set, so a coach's use of it is constrained; it remains a common late-match card in professional volleyball.

Target serve

A serve deliberately aimed at a specific player, disrupting that player's ability to prepare for the next attack. Common targets include a weak receiver, a player who just entered as a substitute, or an outside hitter who needs to attack immediately after receiving. The seam between two receivers, or the short space just in front of the setter, are also frequent targets. The term reflects a modern understanding that where a serve goes matters more than how hard it's hit.

Time-difference attack

An attack in which a hitter deliberately delays their jump by a beat to exploit the gap left by a blocker who is already coming down from an earlier jump. A common combination baits the opposing blocker into jumping early for a teammate's quick attack, then attacks beside or behind that blocker instead. Refined originally in Japanese volleyball, the term carries over directly into English-language broadcasts, and it has long been a standard solution for shorter teams working around taller blockers.

Tip

A soft attack using the fingertips to drop the ball just past the block into open space, rather than hitting it hard; also called a dink. It's useful when the block is fully set or when a shaky receive leaves no clean angle to hit through. If the opposing defense has stepped in close in anticipation, though, it gets dug easily, so relying on it repeatedly after one or two successes quickly gets read and countered.

Triple crown

An award, unique to Korea's V-League, given for recording at least three back-row attacks, three blocks and three service points in a single match. There's no equivalent concept in international volleyball; it was created to honor a player who contributes across all three phases of the game — attack, height and serve. It happens only a handful of times in a season at most, and achieving it becomes the signature moment of that match.

V-League

South Korea's domestic professional volleyball league, run by the Korea Volleyball Federation and launched in 2005. As of the 2024-25 season, both the men's and women's divisions field seven teams each, with the season typically opening in October and concluding with a championship series the following spring. It's an unusual structure in that men's and women's divisions operate side by side within the same league system, and for long stretches the women's division has drawn higher ratings and popularity than the men's.

Video challenge

A system letting a coach request a video review of the previous play, covering calls such as in/out, net touches, whether a ball grazed a blocker's hand, and whether the ball passed between the antennas. If the review favors the challenging team, they keep their challenge; if not, they lose it, which makes saving a challenge for a tight late-match moment a coaching decision in itself.
