These are the words a racing fan meets at the betting window, in the program and in a race report, 86 of them, in plain English. Where Derby Insider has a page that goes deeper, the last column links it; the bet terms also link the bet cost and odds and payout calculators, which do the arithmetic.
Each meaning was checked against the Kentucky Derby's own glossary or, where it does not have the term, the rule or official page that sets it. Type in the box to find a term.
The glossary
Horse racing terms, A to Y
| Term | What it means | More |
|---|---|---|
| Across the board | Three bets in one: win, place and show on the same horse, each its own ticket. If the horse wins, all three pay; second pays place and show; third pays show only. | Kentucky Derby betting |
| Advance deposit wagering (ADW) | Betting online or by phone through an account you fund in advance. Whether you may use one, and from what age, is set by your state and the platform. | Where online betting is legal |
| Allowance race | A race that is not a claiming race, open to horses that meet set conditions, for example horses that have not won three races. | Class handicapping |
| Also-eligible | A horse entered in a race that runs only if a horse in the main field scratches. | |
| Apprentice | A newly licensed jockey who is allowed to carry less weight than other riders for a set period; nicknamed a "bug" rider. | Women jockeys |
| Backstretch | The straight on the far side of the track, between the turns; also the barn area where the horses live. | |
| Bankroll | The money you set aside for betting over a day or a season, an amount you can afford to lose. | Bankroll management |
| Blinkers | A hood with cups that limit a horse's side vision so it pays attention ahead; the program notes when a horse adds or removes them. | |
| Box | An exotic bet that covers every finishing order of the horses you choose. A $1 trifecta box of four horses is 24 combinations, so it costs $24. | Bet cost calculator |
| Breakage | The odd cents dropped when payouts are rounded down. It is figured on each $1, traditionally to the dime, so $2 prices move in 20-cent steps; the rounded-off money is not paid out. Some tracks, NYRA among them, now round to the penny. | Odds and payout calculator |
| Breeze | A workout run easily, the rider holding the horse and asking for little. | Workout reports |
| Broodmare | A filly or mare kept for breeding. | Derby bloodlines |

| Daily double | A bet on the winners of two races in a row, made before the first of them. | Exotic wagering |
| Dam | A horse's mother. | Derby bloodlines |
| Dead heat | Two or more horses finishing in a tie the photo cannot separate. Each pays from its share of the pool, so a dead heat usually pays less than an outright win. | Odds and payout calculator |
