Sports Betting Terms: A Plain Glossary From Action to Vig
In briefBetting has its own vocabulary, and much of it exists to describe a price. This glossary translates the common terms and points out where the operator's cut sits inside them.
Most sports betting terms describe one of three things: what you are betting on, how the price is shown, or what happens to the bet once it is placed. Learn a couple of dozen words and a betting menu stops looking like code. The glossary below is grouped by those three jobs rather than by alphabet, because terms make more sense next to their neighbours. It is written for adults aged 18 or over, and each entry flags where the bookmaker's built-in margin shows up, since that number shapes the long-run result far more than any single pick.
Words for what you are betting on
- Moneyline — a bet on who wins the event outright, with no points added or taken away. A favourite pays less than the stake if it wins; an underdog pays more. In sports where a draw is possible, the market may have three outcomes instead of two.
- Point spread — a margin of points the market adds to the underdog, or takes from the favourite, to even the contest out. A team listed at −6.5 must win by seven or more for a bet on it to land; the side at +6.5 can lose by up to six and still pay.
- Total (over/under) — a bet on the combined score rather than the winner. The sportsbook posts a number and you choose whether the final total lands above or below it.
- Prop — short for proposition, a bet on something inside the game, such as how many shots one player takes.
- Futures — a bet settled weeks or months later, such as who will win a league. The stake stays tied up for the whole wait.
- Parlay (accumulator) — several selections joined into one bet that pays only if every leg wins. Our explainer on what a parlay is shows why the margin stacks up with each leg.
- Live or in-play betting — wagers placed after the event has started, with prices that move as the score changes.
Words for the price
- Odds — the price of a bet, shown in decimal (2.50), fractional (6/4) or American (+150) form. All three describe the same thing; the walk-through on how to read betting odds converts between them.
- Implied probability — the chance of an outcome that a price suggests. Decimal odds of 2.00 imply 50 percent.
- Juice or vig — the bookmaker's cut, built into the prices. When the implied probabilities of every outcome in a market are added together, they come to more than 100 percent, and the excess is the margin.
- −110 — a common American price on spreads and totals: stake 110 to win 100. Both sides of a two-way market are often priced this way, which is the vig at work.
- Favourite and underdog — the side the market expects to win, and the side it does not.
- Line — the number or price on offer at a given moment. When it changes, people say the line has "moved".
- Opening and closing line — the first price posted and the last one available before the start. Price shifts in between are discussed in our piece on interpreting odds shifts.
Words for what happens to the bet
- Stake — the amount risked.
- Return or payout — what comes back on a winning bet, including the stake. Decimal odds show this directly.
- Push — a tie against the spread or total, for example when a team favoured by exactly 3 wins by exactly 3. The stake is normally refunded.
- Void — a cancelled bet, usually because an event was postponed or a player did not take part. Rules on voids vary by sportsbook.
- Settled — a bet that has been marked won, lost, pushed or void.
- Cash out — an offer to close a bet early for a set amount. The figure is priced with a margin of its own.
- Bet slip — the screen or ticket that lists your selections, stake and potential return before you confirm.
- Max bet — the largest stake a sportsbook will accept on a market. Limits are often lower on niche events.
Lingo you will hear around the action
| Term | Meaning in plain words |
|---|---|
| Action | Having money riding on a game, or the total money a book has taken on it |
| Book or sportsbook | The operator taking the bets; see what a sportsbook is |
| Chalk | The favourite, or a bettor who mostly backs favourites |

| Handle | The total amount wagered over a period |
| Hold | The share of the handle the operator keeps after paying winners |
| Hook | The half point in a line such as 6.5, which rules out a push |
| Lock | A pick described as certain; no such bet exists |
| Unit | A personal standard stake used to keep bet sizes consistent |
Three terms people often mix up
Is the vig the same as the hold?
No. The vig is the margin built into a single market's prices. Hold is the result over many bets and many markets: what the operator actually kept. A market can carry a small vig and the operator can still have a poor week if results fall a certain way.
Does a push count as a loss?
Usually not. On a single bet the stake comes back. Inside a parlay, a pushed leg is commonly removed and the payout recalculated on the remaining legs, though house rules decide this.
Is a bigger price better value?
Not on its own. A long price simply reflects a lower chance. Value would mean the true chance is higher than the price implies, and no one can know that reliably.
A word on keeping it light
Knowing the vocabulary makes a bet easier to understand; it does not make it more likely to win. The margin sits inside nearly every term above, so betting suits a set entertainment budget rather than any plan for income. Sports wagering is for adults only, and its legal status differs between countries and states, so confirm the local rules before opening an account.
