What does bet mean?
A bet is a wager — money or something of value staked on the outcome of an uncertain event, usually agreed upon between two or more parties. It functions both as a noun (the stake itself) and as a verb (the act of staking). Bets are central to gambling on sports, cards, races, and games of chance, but the word extends well beyond casinos: people make casual bets with friends over everyday outcomes, and 'bet' also appears figuratively to mean a likely course of action, as in 'your best bet is to apply early.' In informal speech, 'I bet...' expresses confident expectation rather than any literal wager. The word carries connotations of risk, chance, and prediction, and appears in many fixed expressions such as 'hedge your bets,' meaning to spread risk so no single loss is catastrophic. Whether formal or playful, betting always involves uncertainty and a willingness to accept consequences either way.
An agreement in which money or something of value is staked on the predicted outcome of an uncertain event.
"He placed a ten-pound bet on England winning the tournament."
Often used with verbs like 'place', 'make', or 'win'.
To risk money or something of value on the outcome of an uncertain event, or to express confidence that something will happen.
"I'd bet good money that she wins the election."
Past tense and past participle: 'bet'; present participle: 'betting'.
Regular plural form, used for multiple wagers.
"All his bets paid off at once."
The phrase 'hedge your bets' comes from planting actual hedges as boundaries — a physical fence that protected gamblers from losing everything on one wager.

Etymology of bet
The word bet first appears in English in the late 16th or early 17th century. Its precise origin is uncertain, though many etymologists connect it to an older sense of 'abet' meaning to support or encourage, which traces back through Old French. Others suggest it may derive from a dialect word related to betting on cockfights. Because its earliest roots are debated, dictionaries generally note the origin as obscure.
