Polo glossary, A to Z.

Polo's rules differ by governing body. In the entries below, "HPA 2026" means the Hurlingham Polo Association's Rules and Regulations for Polo 2026, and "USPA 2024" means the United States Polo Association's 2024 Outdoor Rules. The USPA revises its rules each year and its 2026 rulebook was not available to us, so check the current book before relying on a USPA figure.

A

AACCP

The Asociación Argentina de Criadores de Caballos de Polo, the breeders' association of the Argentine Polo Pony. La Nación reports it was created in 1984 and has grown from about 50 members to about 400. In 2025 its president told Reuters it would watch the first gene-edited polo clones for four or five years before deciding whether to register them. (Argentine polo pony)

AAP (Asociación Argentina de Polo)

Argentina's governing body for polo, founded on 14 September 1922 at the Hurlingham Club (Wikipedia, secondary). It runs the Argentine Open and the rest of the Triple Crown and sets handicaps for players active in Argentina. La Nación reported in May 2025 that Benjamín Araya was elected its president. (Governing bodies)

Advantage

Under HPA 2026 (Rule 36), an umpire may decline to blow the whistle, or delay it, when stopping play would hurt the team that was fouled. (Fouls and penalties)

All may change

The call that lets every player change ponies when one pony is visibly injured or distressed. It appears in HPA 2026 (Rule 23) and USPA 2024 (Rule 21f); under the USPA rule the injured or distressed pony may not play again in that game. (Welfare rules)

Arena polo

Polo in an enclosed, all-weather arena. The HPA describes an arena of about 300 by 150 feet, three players a side, usually four chukkas, a larger ball, a height-limited goal and no spurs, with ends changed only after each chukka. The HPA's about-polo page says a goal scored from behind the 25-yard line counts two, and the HPA normally sets a player's arena handicap one goal above their outdoor handicap. (Arena, snow and beach polo; Arena technique)

Argentine Open (Abierto Argentino de Polo)

Argentina's top tournament and the final leg of the Triple Crown, played at the Campo Argentino de Polo in Palermo, Buenos Aires. The 2025 final, the 132nd edition, was played over eight chukkas on 7 December 2025, and La Natividad La Dolfina beat Ellerstina Indios Chapaleufu 17-13 (El Ancasti). As of October 2026 the 2026 edition has not started. (Argentine Triple Crown)

Argentine Polo Pony (Polo Argentino)

A breed recognised in 1984, mostly descended from Thoroughbred and Criollo crosses, with no pony ancestry despite the name (Wikipedia, secondary). La Nación reported that 862 of the 945 horses at the 2024 Queen's Cup in England were Polo Argentino, and that polo horses do not have to belong to any particular breed. (Argentine polo pony)

B

Back

Another name for the No. 4, the most defensive player. Meadow Brook Polo Club says the back is usually a long hitter who takes the hit-ins and relies on strong backhands. (Positions)

Backhand

A stroke that sends the ball back the way the player is riding. Dallas Burston Polo Club describes the offside backhand as mainly defensive, hit either to the "tail" (under the pony's tail) or "open" (away from the pony). (The four strokes)

Ball

The outdoor ball is 3 to 3.5 inches across under both rulebooks, but the weights differ: HPA 2026 (Rule 1f) specifies 4.25 to 4.75 ounces (120 to 135 g), while USPA 2024 (Rule 13a) specifies 3.5 to 4.5 ounces. Arena and snow polo use larger balls. (Balls)

Beach polo

Polo on sand in an enclosed arena. Wikipedia (secondary) describes three-player teams, sideboards about 4 feet high and an inflated ball (EBSCO says a plastic ball), and credits Reto Gaudenzi and Rashid Al Habtoor with creating it in Dubai in 2004. (Arena, snow and beach polo)

Bell and horn

The signals that end a chukka. Under HPA 2026 (Rule 10a) a bell at 7 minutes means up to 30 seconds remain, and the chukka ends at the next break in play or on a second bell. USPA 2024 (Rule 14) uses a single horn or bell at 7 minutes and a double horn to end the period. The two differ on the last chukka: HPA 2026 ends it on the first bell unless the scores are tied, while USPA 2024 plays it to the second horn or until a goal is scored (a goal that ties the score does not end it). (Chukkas and timing)

Boards

Low boards along the sidelines that help keep the ball in play. HPA 2026 (Rule 1d) allows boards up to 11 inches (28 cm) high; USPA 2024 (Rule 12h) also sets 11 inches and limits the deflector strip at their base to 3 inches. A full-size boarded field is 160 yards wide under both rulebooks. (The field)

Boots (polo boots)

Tall riding boots worn for play. HPA 2026 requires polo boots and knee pads; USPA 2024 (Rule 4c) requires boots, or boots and half-chaps, covering the calves. The St. Moritz Snow Polo World Cup programme describes knee-high leather boots in dark brown or black, usually with a long front zip; sources disagree on colour. (Boots, knee guards and gloves)

Bowl-in

Dallas Burston Polo Club's term for the umpire rolling the ball down the centre of the lined-up teams. HPA 2026 says the umpire bowls the ball underarm, low and hard between the ranks. See also throw-in. (How polo works)

Breastplate

A strap across the pony's chest that stops the saddle slipping back, as the St. Moritz programme and the South African Polo Association describe it. The HPA 2026 rule text does not require one; the Pony Club's 2026 polo rulebook requires breastplates in most of its sections. (Girths, breastplates and martingales)

Bryan Morrison Trophy

The Arena International played at the All England Polo Club, Hickstead. Its 16th running, on 17 January 2026, was won by England 17-11 over the USA (HPA). (Snow and arena events)

Bump

Dallas Burston Polo Club's word for riding off another player to spoil a shot or take them out of the play. See ride-off. (Riding off and hooking)

C

Calkin (stud)

A small raised grip on a horseshoe. HPA 2026 (Rule 3d) allows a calkin or stud under 0.5 inch (13 mm), fitted only in the last inch of the outside heel of the hind shoe, and strongly recommends removable studs. USPA 2024 (Rule 6) allows dull heel calks on hind shoes only, no more than one inch. (Pony leg protection; Welfare rules)

Cane

The traditional material of the mallet shaft. Wikipedia (secondary) says it is manau cane rather than bamboo; other sources call it bamboo. Wood Mallets, a New Zealand maker, claims manau is now nearly unobtainable and that most cane mallets use Indonesian batu cane. Composite shafts are also made. (Mallets)

Captain

The player who speaks for the team. HPA 2026 requires an on-field captain, named to the umpires before the game and wearing an armband, who is the only player allowed to speak with the umpires; USPA 2024 (Rule 1a) has each team designate a Captain who alone represents it on procedural matters. (How polo works)

Checking

HPA Club Coach Tim Ward's term for a half halt that gathers the pony like a compressed spring, to buy time for a shot or regain control of speed (POLO+10, 2014). (Riding one-handed)

Chogān (chovgan)

The Persian name for the mounted ball game from which polo descends. UNESCO inscribed "Chogān" for Iran on its Intangible Cultural Heritage list in 2017, and Azerbaijan's "Chovqan" on its list in need of urgent safeguarding in 2013. (Origins)

Chukka (chukker)

A period of play: "chukka" in HPA usage, "chukker" in USPA usage. HPA 2026 (Rule 10a) sets a maximum of 7.5 minutes and (Rule 8a) a standard game of 4 to 6 chukkas; USPA 2024 allows at most 6 regular periods. Both use 3-minute intervals with 5 minutes at half time. Argentina's top opens run longer: the 2025 Argentine Open final was eight chukkas. (Chukkas and timing)

Clone

A horse produced from another horse's cells. Wikipedia (secondary) dates the first polo clone to 2010, made through Crestview Genetics for Adolfo Cambiaso. Contemporary reports name Show Me, a clone of Sage, as the first clone to play an Argentine Open final, on 7 December 2013, though Popular Science (2026) calls the 2016 Palermo final the first time clones played. La Nación reported about 300 clones in one season of the Polo Argentino breed (2024). (Cloning and breeding; Lineage)

Concussion stand-down

The minimum time out of play after a concussion. HPA 2026 (Rule 2.2m) sets at least 21 days, counting the day of the incident as day zero, with a narrow exception for baseline-tested high-goal players. The Australian Polo Federation's 2025 policy sets at least 12 days after symptoms clear for adults and 21 for players 18 and under, unless a health practitioner clears an earlier return. USPA 2024 (Rule 21d) bars a player who was knocked unconscious from playing again that day. Follow medical advice and your governing body's current rules. (Injuries and concussion)

Coronation Cup

The feature match of the HPA's International Day at Guards Polo Club. The HPA says it was first played in 1911 and has been played at International Day since 1971. England beat Uruguay for it on 25 July 2026 (final score not found). (UK high goal)

Crossing

Riding across the path of a player who has precedence. HPA 2026 (Rule 26) forbids it except at a distance with not the slightest risk of collision or danger; USPA 2024 (Rule 24) forbids entering or crossing another player's right of way on the same terms. (Line of the ball)

Cuartetera

Adolfo Cambiaso's best-known mare, an embryo-transfer foal by Sportivo out of Lambada according to La Dolfina's own record. She won the Lady Susan Townley Cup at Palermo in 2009, 2010 and 2014, her first clones were born in 2010, and she died in May 2023 aged 22 (La Nación). (Lineage)

Cup of the Americas

A series between United States and Argentine teams that began in 1928; the US won the first two series and Argentina won from 1936 onward (Wikipedia, secondary). No modern edition was found. (International cups; The international era)

Curb bit

For curb bits, HPA 2026 (Rule 3c) limits the total cheek or shank length to 6 inches (15.2 cm). The same rule bans any bit, single or double, whose mouthpiece is under 0.25 inch (6.5 mm) at its narrowest. (Bits and bridles)

C.V. Whitney Cup

The first of the three 18 to 22 goal tournaments in the USPA's Gauntlet of Polo at the National Polo Center, Wellington, Florida; in 2026 it ran from 11 February to 1 March. (US high goal)

D

Dangerous riding

Riding that puts players or ponies at risk. HPA 2026 (Rule 34) lists examples including a full-power swing at close quarters, zigzagging, pulling across another player and swinging the stick wildly ("windmill or helicopter"). USPA 2024 (Rule 26) lists factors the umpire weighs, such as relative speed, mount size, position and the angle of approach, and says knocking a mount off balance is a dangerous ride-off by definition. (Fouls and penalties)

Divot stomping

The half-time custom of spectators walking onto the field to tread back the turf torn up by hooves. Dallas Burston Polo Club says it reduces the risk of falls and lets the ball run truer, and that its origin is unclear; we saw that page only as a search summary. None of the rulebooks read (HPA 2026, USPA 2024, AAP 2026 women's) mentions it: it is a custom, not a rule. (Watching polo)

Draw reins

A second set of reins run toward the girth for extra stopping power. The St. Moritz programme says a polo bridle usually has two reins, one set often used this way, and Wikipedia (secondary) says polo players often pair a gag with draw reins because they ride one-handed. (Bits and bridles)

E

Embryo transfer (ET)

Breeding in which a mare's embryo is carried by a surrogate mare, which Reuters (2025) says polo has long used. A study of Polo Argentino pedigree records found that about 75 percent of horses born 2006 to 2015 came from embryo transfer, and La Dolfina marks such foals "ET" on its horse pages. (Cloning and breeding)

Ends, changing

Teams swap the goal they attack. In outdoor polo this happens after every goal under HPA 2026 (Rule 13a, which restarts with a Penalty 5b instead of a throw-in when the goal came from a Penalty 1). Under USPA 2024, Rule 22e(1) changes ends for the centre throw-in after a goal, except goals awarded on handicap or by Penalty 1; a Penalty 1 goal is followed by a Penalty 5b and a change in direction (Rule 37). In arena polo the HPA changes ends only after each chukka. (How polo works)

Extra chukka (overtime, golden goal)

Play after a tied match when a result is needed. HPA 2026 (Rule 10c) plays sudden death ("golden goal") until a goal or the second bell, with goals normally widened from the second extra chukka; USPA 2024 (Rule 14c) plays overtime periods until one side scores. (Chukkas and timing)

Eye protection

Sports glasses, goggles or a face guard. HPA 2026 requires it for all players; USPA 2024 (Rule 4a) makes it mandatory only for players under 18 and strongly encourages it for everyone else. The Pony Club's 2026 polo rulebook requires it for all players. (Eye and face protection)

F

Face guard

A guard mounted on the helmet in front of the face. The US standard, NOCSAE ND055, fires a polo ball at 90 mph at the guard and allows no contact with the eye area; packaging must say the guard is not NOCSAE compliant unless fitted to a listed NOCSAE polo helmet. (Eye and face protection)

FIP (Federation of International Polo)

Polo's international federation, headquartered in Montevideo, Uruguay, with more than 80 national associations. FIP gives its founding year as 1982; the Australian Polo Federation says 1984. FIP does not publish its own playing rulebook: it endorses the HPA, AAP and USPA rules as the basis of international polo. (Governing bodies)

Flags, cards and the sin bin

Disciplinary signals added to a penalty, and the two books differ. Under HPA 2026 (Rule 50) two yellow flags send a player to the sin bin for two minutes of playing time; a red flag sends the player off for the rest of the match (a substitute may come on after 2 minutes of play) and brings a suspension for the player's next two matches in that tournament, subject to confirmation by the HPA's disciplinary panel (DRP). USPA 2024 (Rule 33) uses cards: a second yellow means two minutes off with no substitute, and a red means the rest of the game, no substitute for the next four minutes and suspension for the player's next game of equal or higher handicap. (Fouls and penalties)

Forehand

A stroke that sends the ball forward. Dallas Burston Polo Club calls the offside forehand the first shot players learn and the most common, played as a full shot or as a half shot to tap or dribble the ball. (The four strokes)

Forty-goal team

A team of four 10-goal players, the maximum on the Argentine scale. Wikipedia (secondary) says Coronel Suárez became the first team to play the Argentine Open at 40 goals in 1975; La Natividad La Dolfina played the 2025 final as a 40-goal team. (Handicaps; Argentine Triple Crown)

Foul

Any infringement of the rules, as HPA 2026 (Rule 6a) defines it. The umpires award a numbered penalty according to how serious the foul was and where it happened. (Fouls and penalties)

Free change of ponies

A short stoppage in which players may change ponies mid-chukka. HPA 2026 (Rule 2.4s) allows free changes, limited to one minute, under an amber Met Office heat warning or a forecast of 28 C or more. The AAP's 2026 women's regulations build a general change of horses, limited to one minute, into roughly the middle of each chukka. (Welfare rules)

G

Gag bit and Pelham

The two bits the St. Moritz programme names as most commonly used in polo: a large-ring gag or a Pelham, with other bits chosen to suit the pony. Wikipedia (secondary) says gags are most often seen in polo, and that a rein on the bottom ring of a gag gives much stronger leverage. The Pony Club's 2026 rulebook allows a rope-ring gag only with two reins. (Bits and bridles)

Gauntlet of Polo

The USPA's three-tournament 18 to 22 goal series at the National Polo Center in Wellington, Florida (the former International Polo Club grounds, acquired by the USPA in June 2022, per Wikipedia, secondary): the C.V. Whitney Cup, the USPA Gold Cup and the U.S. Open Polo Championship. In 2026 Pilot won the Gold Cup and the U.S. Open back to back (USPA). (US high goal)

Gene editing

Changing a horse's DNA directly. HPA 2026 (Rule 3b) bars any pony that has undergone gene editing, genome editing, genetic therapy or gene doping for competitive purposes. Reuters reported in 2025 that Kheiron Biotech had produced five CRISPR-edited clones of Polo Pureza (described as a mare by Forbes Argentina and Horse Canada, and as "a prize-winning horse" in the syndicated Reuters report), and that the AAP had banned gene-edited horses from competition; another report, which could not be confirmed, said Argentine rules did not yet tell such horses apart. (Cloning and breeding)

Goal

Scored when the ball passes between the posts, or the imaginary lines rising from their inner faces, and over the goal line. Both HPA 2026 (Rule 7c) and USPA 2024 (Rule 18) say a ball hit directly over a post does not count. Posts stand 8 yards apart and at least 10 feet high, and must give way in a collision. Outdoors every goal counts one; in HPA arena polo a goal from behind the 25-yard line counts two. (How polo works; The field)

Goal judge

An official behind each goal. Under HPA 2026 (Rule 4d) the goal judge gives evidence on goals and play near goal but the umpire decides; under USPA 2024 (Rule 9) goal judges wave the flag overhead for a goal and at their feet for a ball over the end line. (Umpires and officials)

Goals on handicap

The head start a lower-rated team receives. HPA 2026 (Rule 7b) multiplies the difference in team handicaps by the number of chukkas and divides by 6, counting any fraction as half a goal; USPA 2024 (Rule 19) uses the same formula and also uses the half goals as tie-breakers. Handicap goals count like any other goal. (Handicaps; Handicap calculator)

Gold Cup

A name shared by several tournaments. The Gold Cup for the British Open at Cowdray Park, first played in 1956, is played at 22 goals; Gaston beat Dubai 9-8 in the 2026 final. The USPA Gold Cup is the middle leg of the Gauntlet of Polo, and Sotogrande in Spain has its own Copa de Oro (Gold Cup). (UK high goal; US high goal)

Groom

The person who cares for and prepares a player's ponies; in Argentina, a petisero. HPA 2026 (Rule 2.2j) requires everyone riding at a polo ground, grooms included, to wear approved headgear. (The string and grooms)

H

Hackamore

A bitless bridle. HPA 2026 (Rule 3c) bans hackamores and other bitless bridles in play, though clubs may allow them in practice chukkas. (Bits and bridles)

Half seat

The polo riding position, standing slightly off the saddle in short stirrups. HPA Club Coach Tim Ward teaches it with heels down, toes forward and feet behind the girth (POLO+10, 2014). Schools describe it differently: one calls it deeper and more centred than a show jumper's seat, another a forward seat, and a lesson report says it is more upright than a jumper's two-point. (The polo seat)

Half shot

A shorter swing. HPA 2026 defines it as a swing in which the stick head starts its downward path below the hitter's shoulder, and limits some restarts to it, such as the follow-up after a mishit Penalty 3. (The four strokes; Fouls and penalties)

Handicap

A player's rating in "goals", reflecting skill and value to the team rather than goals scored (HPA). The scales differ: HPA 2026 runs from -2 (an introductory rating) to 10; Argentina's AAP scale runs from 0 to 10; USPA 2024 uses negative and half-goal values such as -0.5, 0.5 and 1.5. A team's handicap is the sum of its players'. (Handicaps)

Helmet

Required under both books: whenever mounted under HPA 2026, and in USPA Events and Club Events under USPA 2024. HPA 2026 (Rule 2.3) requires a helmet with the chinstrap or harness fastened, of a type approved under the HPA Helmet Regulations, and extends the rule to everyone riding at a polo ground, grooms included. USPA 2024 (Rule 4a) requires a helmet with chin strap certified to NOCSAE ND050 and does not let clubs vary the rule. The 2026 HPA list of approved standards was not retrieved; a 2023 restatement by the German federation listed PAS015:2011, VG1, UTAC/CRITT and NOCSAE, plus newer versions such as EN1384:2017, and required a QC mark as well as type approval. Check the label on your helmet and your current rules. (Helmets)

High goal

The top level of handicap polo. The HPA's about-polo page gives high goal as 17 to 22 and 15 to 18 goals of team handicap; the Gold Cup at Cowdray is played at 22 goals, and the USPA's Gauntlet of Polo at 18 to 22. (Handicaps; UK high goal)

Hockey on horseback

What the game was called when officers of the 10th Hussars, led by Edward "Chicken" Hartopp, organised England's first match on Hounslow Heath in 1869, according to the HPA. (Polo in England)

Hogged mane

A mane clipped very short so sticks, reins and hands do not tangle in it, as the St. Moritz programme explains; Wikipedia (secondary) calls it roached. The programme adds that young ponies still in training can be spotted by their longer, unhogged manes. (Pony leg protection; The polo pony)

Hook

Blocking an opponent's swing with your own stick. HPA 2026 (Rule 30) and USPA 2024 (Rule 28) agree on the core: only from the same side of the opponent's pony as the ball or directly behind, never over, under or across the pony, only while the opponent is hitting with the stick below the shoulder, and never with excessive force. HPA 2026 adds that a nearside backhand may not be hooked from behind the player. (Riding off and hooking)

HPA (Hurlingham Polo Association)

The governing body for polo in the UK and Ireland. It traces itself to the Hurlingham Polo Committee of 1875 and took its present name in 1925 (HPA). FIP lists it as one of its three Category A full members. (Governing bodies)

Hurlingham

Two clubs important to polo. The Hurlingham Club in London held its first polo match in 1874, and its polo committee drew up the first English rules, in 1875 according to the HPA (other sources give 1873 or 1874). The Hurlingham Club in Argentina, founded in 1888 (Wikipedia, secondary), hosts the Hurlingham Open, a Triple Crown leg; La Natividad La Dolfina beat La Hache 18-14 in its 2026 final on 4 October 2026 (Prensa Polo). (Polo in England; Argentine Triple Crown)

I

Intercollegiate and interscholastic (I/I) polo

USPA school and college polo. Horse Nation (2015) describes it as three a side in an arena, usually on dirt, with every game using a split string, so riders do not need their own ponies. (College and youth)

K

Knee guards (knee pads)

Padded protection for the knees, which are exposed in ride-offs. HPA 2026 requires knee pads in play, and the Pony Club's 2026 rulebook makes them compulsory in most sections. The St. Moritz programme describes padded leather with Velcro straps. (Boots, knee guards and gloves)

Knock-in (hit-in)

The restart when the attacking team sends the ball over the back line, likened by Dallas Burston Polo Club to a football goal kick. Under HPA 2026 (Rule 14) the defenders hit in from where the ball crossed, at least 4 yards from the posts, within 10 seconds of the call to play. USPA 2024 also allows 10 seconds (Rule 22) but places the ball no nearer than 5 yards to the posts or side boards (Rule 9b). (How polo works)

L

Lady Susan Townley Cup

The award for the best horse of the Argentine Open final at Palermo. Cuartetera won it in 2009, 2010 and 2014 (Horse Nation; La Dolfina). (Lineage)

Line of the ball

The path the ball is travelling, or has travelled, extended in both directions; it decides who has precedence. HPA 2026 (Rule 27) makes it the central reference and includes the path after deflections. USPA 2024 (Rule 23) defines it the same way and adds that if a dead ball is hit at and missed, the line is the direction the player was riding. (Line of the ball)

Line, man, ball

A priority order taught by Houston Polo Club instructor Mark Prinsloo: join the line first, then take your opponent, and only then go for the ball (Horse Nation, 2015). (Team play)

Low goal

Handicap polo at the lower team levels: 8 goals and below on the HPA's about-polo page, with HPA 2026 tournament bands of 4 to 8, 2 to 6 and 0 to 4. (Handicaps)

M

Mallet (polo stick)

The stick used to hit the ball: "mallet" is US usage and "polo stick" British (Wikipedia, secondary). HPA 2026 sets no length, weight or material limit, only rules on how it is used, and allows it to be held only in the right hand to hit or hook. The ball is struck with the side of the head, not the end. Sources give typical lengths of 48 to 53 inches (Krenkerup Polo) or 50 to 53 inches (Wikipedia, secondary). (Mallets; Mallet length)

Manipuri pony

One of India's five recognised horse breeds, often called the only living original polo pony, usually 11 to 13 hands tall (Scroll.in). Scroll reports that numbers have fallen sharply since 2003. (Manipur and the British)

Marking

Staying with an opponent. Meadow Brook Polo Club says each player's two jobs are to mark an opposite number in defence and to get free of them in attack, with the No. 1 marking the opposing No. 4 and the No. 2 the opposing No. 3. In HPA 2026's delay rule (Rule 28d), a player is "marked" when an opponent is within two pony lengths. (Positions)

Martingale (standing martingale)

A strap that limits how far the pony can throw its head up and back. The St. Moritz programme says this matters because players lean over the pony's head and could be hurt. The HPA 2026 rule text found does not require one; the Pony Club's 2026 rulebook requires a leather standing martingale on every pony. (Girths, breastplates and martingales)

Medium goal

The middle band of handicap polo. HPA sources disagree on its limits: the HPA's about-polo page gives 10 to 15 goals, while the HPA 2026 rulebook splits this into Medium (12 to 15) and Intermediate (10 to 12). (Handicaps)

N

Nearside

The pony's left side. Dallas Burston Polo Club says the nearside forehand is harder than the offside forehand because the stick stays in the right hand, so the player must twist and reach over the pony without hitting it. (Nearside shots)

Neck rein

Steering by laying the rein against the pony's neck, which asks it to turn away from the pressure (Wikipedia, secondary). Argentina Polo School calls it one of the first adjustments a new polo rider must make, since polo is ridden with the reins in one hand. (Riding one-handed)

Neck shot

A ball hit under the pony's neck, as Dallas Burston Polo Club defines it. Argentina Polo School says the forehand neck shot sends the ball diagonally across the pony's front, to change the angle toward goal, pass or avoid a defender. (The four strokes)

No. 1

The most attacking position. The HPA says the No. 1 attacks and scores; Meadow Brook Polo Club says the No. 1 marks the opposing No. 4. (Positions)

No. 2

A position sources describe differently. The HPA says the No. 2 balances attack and defence; Meadow Brook calls the No. 2 a forward whose marking job is the opposing No. 3; POLO+10 places the No. 2 in midfield. (Positions)

No. 3

The playmaker. The HPA calls the No. 3 the main strategist and usually the strongest hitter, and the Museum of Polo calls it the field general. The St. Moritz rules leaflet says the captain usually wears No. 3. (Positions)

No. 4

The defensive position, also called the back. The Museum of Polo says the No. 4 guards the goal; Meadow Brook says the No. 4 usually takes the hit-ins. Players may move anywhere on the field whatever their number (HPA). (Positions)

NOCSAE ND050

The US performance standard for newly manufactured polo helmets. USPA 2024 (Rule 4a) has required player helmets to be certified to it since 1 May 2021, and clubs may not vary the helmet rule. NOCSAE also appears among the standards the HPA accepted in its 2023 helmet list; the 2026 HPA Helmet Regulations themselves were not retrieved. Check the label on your helmet and your current rules. (Helmets)

O

Offside

The pony's right side, where the stick is carried. Under HPA 2026 (Rule 27b) a player on the exact line of the ball with the ball on their offside has precedence. (The four strokes; Line of the ball)

Olympic polo

Polo was played at five Olympic Games, 1900, 1908, 1920, 1924 and 1936, always as a men's event, and has not been on the programme since, according to Olympedia. Great Britain won three golds and Argentina two. (Olympic polo)

On the flat

Played without handicap goals. The Virginia Polo primer says open tournaments are played this way, and the AAP's 2026 women's rules put every women's match on handicap except the Women's Open. The rule of thumb does not hold everywhere: the British Open at Cowdray is a handicap tournament. (Watching polo)

Overgirth (surcingle)

An extra girth that adds stability and backs up a girth that breaks (St. Moritz programme). HPA 2026 allows an equaliser or humane girth only together with an overgirth or surcingle, and does not permit cinch girths. (Girths, breastplates and martingales)

Overreach boots (bell boots)

Boots around the pastern that protect the heel from the pony's own hooves and other ponies', as the St. Moritz programme describes them. (Pony leg protection)

P

Palermo

Shorthand for the Argentine Open, after its home, the Campo Argentino de Polo in the Palermo district of Buenos Aires. La Nación's guide says the ground opened on 27 October 1928, with fields of 275 by 146 m and boards 27 cm high. (Argentine Triple Crown)

Patron

An amateur player who funds a team and plays alongside professionals, typically three of them in higher-handicap tournaments, as Glion's guide describes it. Cowdray named a Best Patron at the 2026 Gold Cup final. (How the game changed)

Penalty 1

The heaviest penalty in both books: for a dangerous or deliberate foul near goal that saves a goal, the fouled team is awarded a goal and play restarts with a Penalty 5b to them after ends are changed (HPA 2026 Rule 38; USPA 2024 Rule 37). (Fouls and penalties)

Penalty 2

A free hit for a foul close to goal. Under HPA 2026 (Rule 39) the fouled captain chooses an undefended hit from the spot or from 30 yards opposite the centre of goal. USPA 2024 offers the centre of the 30-yard line or the spot; for a spot hit no defender may be within 30 yards. (Fouls and penalties)

Penalty 3

A free hit from 40 yards opposite the centre of goal with the defenders behind their back line. Under HPA 2026 (Rule 40) it is defended: the defenders wait behind their back line only until the ball is hit or hit at. Under USPA 2024 it is undefended by default, and the Host Tournament Committee may make it defended in events of 8 goals and above with two certified professional umpires. (Fouls and penalties)

Penalty 4

A free hit from the centre of the 60-yard line. The books differ on the defence: HPA 2026 (Rule 41) keeps defenders 40 yards from the Penalty 4 line, while USPA 2024 keeps them behind the 30-yard line. (Fouls and penalties)

Penalty 5 (5a and 5b)

A free hit from the spot of the foul (5a) or from the centre of the field (5b), with defenders 30 yards away. For a 5a, HPA 2026 places the ball at least 4 yards from the boards, USPA 2024 at least 5 yards from the boards or sideline. (Fouls and penalties)

Penalty 6 (Corner 60, Safety)

Awarded when a defender hits the ball over their own back line: a free hit from the 60-yard line opposite where the ball crossed, no more than 40 yards from the centre. HPA 2026 (Rule 44) calls it the Corner 60; USPA 2024 calls it a Safety. (Fouls and penalties)

Penalties 7 and above

Here the numbering splits. HPA 2026 uses Penalty 7a and 7b for infringements during a penalty hit, Penalty 8 for a throw-in toward the nearest boards and Penalty 9 for a pony or player sent off for illegal equipment. USPA 2024 uses Penalty 7 for removing a player after a disabling foul, 8 for a mount ordered off, 9 for forfeiture of the game and 10 for excluding a player. (Fouls and penalties)

Petisero

An Argentine polo groom, from the Spanish "petiso", a small horse (Argentina Polo School, 2025). La Nación reported in 2017 that most petiseros working the English season are young Argentines, often starting work around 5 a.m. (The string and grooms)

Polo bandages

Bandages wrapped around a pony's legs, not too tightly, to protect the tendons (St. Moritz programme). HPA 2026 (Rule 3c) requires bandages or boots on all four legs; USPA 2024 (Rule 6) requires them on the front legs and only recommends them behind. Under HPA 2026 a trailing bandage stops play at once. (Pony leg protection)

Polocrosse

A separate sport that combines polo and lacrosse. The UK Polocrosse Association describes teams of six in two sections of three, a racquet with a loose net, and one horse per player for a normal tournament. (Arena, snow and beach polo)

Pony (polo pony)

The horse a player rides, whatever its size. The HPA says the word survives from an original 14-hand height limit abolished after the First World War; the Museum of Polo gives the old limit as 13 hands 2 inches. Today HPA 2026 (Rule 3a) allows ponies of any height, and USPA 2024 (Rule 5a) defines a mount as a horse or pony of any breed or size. (The polo pony)

Pony Club polo

Youth polo in the UK for ages 6 to 21, organised in nine sections and built on "one player, one pony", according to the Pony Club's 2026 polo rulebook, which names the Gannon as its flagship section and bans spurs in every section. (College and youth; Getting started)

Practice chukka

An informal chukka for practice. Melbourne City Polo Club, for example, splits its practice chukkas into young-horse, fast and slow chukkas. HPA 2026 lets clubs allow hackamores in practice chukkas. (Practice)

Q

Queen's Cup

The Cartier Queen's Cup at Guards Polo Club, Windsor, first played in 1960 on the Queen's Ground (HPA). It was still played under that name in 2025 and 2026; in 2025 Park Place beat La Dolfina/Marqués de Riscal 9-8. (UK high goal)

R

Referee (third man)

The off-field official who decides only when the two umpires disagree. Under HPA 2026 (Rule 4b) the referee sits in a raised spot at the centre of the ground and, if unable to judge, rules "No Foul". USPA 2024 (Rule 8) staffs a game with two mounted umpires and a referee, or with three mounted umpires. (Umpires and officials)

Ride-off

Pushing an opponent off the line with your pony. Under HPA 2026 (Rule 31) the ponies must be at the same speed, shoulder to shoulder and meeting at a safe angle, with elbows kept close to the side and no pushing with head, hand, arm or elbow. USPA 2024 (Rule 27) differs on the arm: a player may push with the arm above the elbow if the elbow stays close to the side. (Riding off and hooking)

Right of way

A term the two books use differently. USPA 2024 (Rule 24) makes it the central concept: a right of way always exists near the ball, extends ahead of the entitled player, is distinct from the line of the ball, and does not depend on who hit last; its interpretations say there is no nearside right of way. HPA 2026 frames precedence around the line of the ball (Rule 27) and uses right of way (Rule 28) for the player in possession continuing down the line. (Line of the ball)

Rules test

The HPA's test for new players. Under HPA 2026 a club may award the introductory -2 handicap to a member who has passed it and is judged safe. (Getting started)

S

Safety zone

The prepared ground around the field. HPA 2026 (Rule 1b) recommends 10 yards beyond the sidelines or boards and at least 30 yards beyond the back lines, and treats incidents there as on the field. USPA 2024 (Rule 12) recommends a side safety zone of at least 10 yards plus a runoff area beyond the lines. (The field)

Sagol kangjei

The Manipuri game from which, the Government of Manipur says, modern polo descends. It is played seven a side (Scroll.in), and Manipur calls the Mapal Kangjeibung ground in Imphal the world's oldest polo ground. (Manipur and the British)

Sandwiching

Two teammates riding off one opponent at once, listed as rough play in HPA 2026 (Rule 33). (Fouls and penalties)

Shootout

A way to settle a tie with free hits at an undefended goal, and the defaults differ. HPA 2026 (Annex D) has one nominated player per team take best-of-five penalties from the 60-yard line, then sudden death. USPA 2024 (Rule 14d) hits from the 40-yard line, ideally with every player on both teams taking a turn. (Chukkas and timing)

Sling

The webbed loop at the top of the mallet handle. Wikipedia (secondary) says it wraps around the thumb, and England captain Luke Tomlinson describes putting the thumb through it and wrapping it around the back of the hand (Shortlist, 2011). (Mallets; The swing)

Snow polo

Polo on snow. Blue News reports that Reto Gaudenzi staged the first tournament on frozen Lake St. Moritz in 1985. The St. Moritz rules leaflet (2024) gives four players a side, a field of about 90 by 220 m and goals 7.3 m wide with no crossbar; Wikipedia (secondary) says snow polo usually has three per team. (Arena, snow and beach polo; Snow and arena events)

Split string

A pool of ponies shared between both teams. In USPA intercollegiate and interscholastic arena polo every game uses one, so each pony plays once for each team and riders draw ponies at random (Horse Nation, 2015). (Arena technique)

Spurs

HPA 2026 (Rule 2.3b) allows only smooth, rounded spurs with a single shank no longer than 2 cm pointing to the rear, and bans rowels; a pony injured by spurs is sent off for the day and the player gets an automatic yellow flag. USPA 2024 bans sharp spurs and says spurs may not be used unnecessarily or excessively. HPA arena polo and every Pony Club section ban spurs. (Spurs and whips)

Stick and ball

Solo practice: warming up the pony, then hitting around a practice field at less than full strength to build muscle memory, as Global Polo describes it. (Practice)

String

The ponies a player brings to play, changing between chukkas. Wikipedia (secondary) says a player needs at least two horses per match. HPA 2026 (Rule 2.4e) bars a pony from playing more than 7.5 minutes without a 10-minute break, or more than 15 minutes in all, in normal match time. Sources give different typical string sizes and none could be confirmed. (The string and grooms)

T

T handicap

A label that means different things by body. In the AAP's 2026 women's regulations, "T" is a temporary handicap for a foreign player who holds none; in Western Australia clubs may assign a "T" handicap to a player judged experienced enough; USPA 2024 (Rule 2f) uses a "T" handicap without defining it in the text read. (Handicaps)

Tail shot

A ball hit behind the pony, under its tail; Dallas Burston Polo Club describes the offside backhand sent this way. The St. Moritz rules leaflet calls the tail stroke one of the trickiest manoeuvres. (The four strokes)

Tails, tied up

HPA 2026 (Rule 3c) requires playing ponies to have their tails put up, though an umpire's pony need not. The St. Moritz programme says tails are plaited and tied, usually with tape, so sticks do not catch in them. (Pony leg protection)

Ten-goal player

A player at the top of the handicap scale. Each body rates separately: the AAP named six men at 10 goals for 2026, and a player can be 10 in one country and 9 in another. (Top players; Handicaps)

Throw-in

How play starts and restarts. Under HPA 2026 (Rule 11) the teams line up on their own sides of an imaginary line on the centre line, no player within 5 yards of the umpire, who bowls the ball underarm, low and hard between them; USPA 2024 (Rule 20) also has the umpire throw underhand and hard with players at least 5 yards away. After a goal, play restarts with a throw-in at the centre (HPA 2026 Rule 13a, USPA 2024 Rule 22e(1)), except after a Penalty 1 goal, when both books restart with a Penalty 5b. (How polo works)

Tipa

The hardwood usually used for mallet heads (Wikipedia, secondary). A Jaipur mallet maker interviewed by PARI (2023) regards Argentine-style tipa heads as superior to the beech and maple his workshop uses. (Mallets)

Tortugas Open

One of the three opens of the Argentine Triple Crown, dated by Global Polo to 1907. As of October 2026 the 86th edition is in progress, with matches at the AAP's Alfredo Lalor complex in Pilar. (Argentine Triple Crown)

Triple Crown (Triple Corona)

The AAP's three spring opens: Hurlingham, Tortugas and the Argentine Open at Palermo. Sources disagree on the order: the AAP put Hurlingham first in 2025, while other sources call Tortugas the first leg. La Natividad La Dolfina won all three in 2025; the 2026 series is in progress as of October 2026. (Argentine Triple Crown)

Tzykanion

The Byzantine form of the game, taken from Sasanian Persia; Emperor Theodosius II built a ground for it in the Great Palace of Constantinople (Wikipedia, secondary). (Origins)

U

Umpire

A mounted official who controls the game. HPA 2026 normally uses two mounted umpires, with a single umpire allowed under tournament conditions; USPA 2024 uses two mounted umpires and a referee, or three mounted umpires. Meadow Brook Polo Club notes umpires wear black-and-white shirts, and HPA 2026 bars black-and-white vertical stripes from team shirts. (Umpires and officials)

U.S. Open Polo Championship

Established in 1904 and the final leg of the Gauntlet of Polo. Eleven teams played in 2026, and Pilot beat BTA 15-10 in the final on 26 April 2026 at the National Polo Center (USPA). (US high goal)

USPA (United States Polo Association)

The governing body for polo in the United States, founded on 21 March 1890 as the Polo Association (Wikipedia, secondary), and one of FIP's three Category A members. This site cites its 2024 Outdoor Rules; the USPA revises its rules each year, so check the current book. (Governing bodies)

V

Victor Ludorum

The HPA's points competition across tournaments of each level. HPA 2026 sets the levels as High (17 to 22 and 15 to 18 goals), Medium (12 to 15), Intermediate (10 to 12) and Low (4 to 8, 2 to 6 and 0 to 4), with Victrix levels for women's polo. (Handicaps)

W

Westchester Cup

The match series between Britain (now England) and the United States, first played at Newport, Rhode Island, in 1886, when Great Britain won (HPA). England won the most recent edition found, 12-9 at the National Polo Center on 31 March 2023, with the USA still ahead 11 wins to 9 (USPA). (International cups)

Whip

HPA 2026 (Rule 2.3c) allows a whip no longer than 48 inches including any tag, used only in the left hand while the ball is in play, and only down the shoulder or on the quarters. USPA 2024 (Rule 5g) bans unnecessary or excessive use of the crop, and says a single strike loud enough for a spectator to hear may be penalised. (Spurs and whips)

Widened goals

Goals made wider to settle extra time sooner. HPA 2026 places the sockets 4 yards out from each post and normally widens the goals from the second chukka of extra time. (Chukkas and timing)

Women's handicap

A separate rating for women-only polo. The HPA introduced one in 2015, and HPA 2026 spreads it from -2 to 10, with a guide for converting a first women's rating from the open one. The AAP's women's handicap runs from 0 to 10 and applies only in women's tournaments. (Women's polo)

Wooden horse

A static replica horse for practising the swing. Yale polo players have used one in the "hitting cage" of Payne Whitney Gymnasium since 1932, and a US patent describes the usual set-up of a wooden horse in a dish-shaped surface so hit balls roll back. (Practice gear; Practice)

World Polo Championship

FIP's national-team championship, played at 10 to 14 goals with horses supplied by the host and pooled among the teams. Spain beat the USA 11-10 in overtime in 2022. FIP says the next edition will be held in Uruguay in 2027, though Gulf Today had reported in 2023 that the UAE would host it in December 2026. (World Polo Championship)

Y

Your line

A teammate's call telling a player they have the right of way to the ball, as Dallas Burston Polo Club defines it. (Team play)
