A more thorough explanation:

Definition: Wager refers to the money or other consideration that is risked on an uncertain event, such as a bet or gamble. It can also refer to a promise to pay money or other consideration on the occurrence of an uncertain event.

Examples:

• John placed a wager of $50 on his favorite football team to win the game.
• Samantha made a wager with her friend that she could finish reading a book in one day.
• A company made a wager with its employees that if they met their sales target, they would receive a bonus.

The examples illustrate how wager refers to the money or other consideration that is risked on an uncertain event. In the first example, John is risking $50 on the uncertain outcome of the football game. In the second example, Samantha is making a bet with her friend that she can finish reading a book in one day. In the third example, the company is promising to pay a bonus to its employees if they meet their sales target, which is an uncertain event.
