Deposit (finance)

A deposit is like putting money in a piggy bank. You take some money you have and give it to someone else, like a bank or a store, to keep it safe. When you want your money back, you can go get it from the bank or use it to buy things at the store. The bank might even give you more money back over time for keeping your money with them, kind of like a reward for letting them use your money to help other people.
