Bail is like a special kind of money that people give to the court so they can get out of jail while they wait for their trial.
When someone is accused of doing something wrong, they might be put in jail until they have their trial. But sometimes, they can give the court some money called bail, and the court will let them go home and wait for their trial there.
The idea is that if someone gives the court enough money, they are more likely to show up for their trial because they don't want to lose that money. It's like a promise they make to the court that they will come back for their trial and follow all the rules.
If the person shows up for their trial and does everything they're supposed to do, they get their bail money back at the end. But if they don't show up or break any of the rules, they lose their bail money and might get in even more trouble.
So, bail helps people get out of jail while they wait for their trial, as long as they promise to show up and do what they're supposed to do.
