Okay kiddo, have you ever borrowed money from someone? Maybe from your mom or dad? Well, when you borrow money from someone you owe them something called a debt. A bond is a way for big companies, governments or even cities to borrow money by selling small pieces of debt to people like you and me.
Now, imagine you want to buy a bond from a company called Bondz Inc. When you buy a bond from Bondz Inc, you are loaning them money, just like you would loan your friend money. In return, Bondz Inc will promise to pay you back that money with some extra money too (this extra money is called interest).
So when you buy a bond, you are basically becoming a little lender for that company, government or city. They promise to pay you back your money plus interest over time.
Now, when you buy a bond, you are giving that company, government or city money and they will use it for a specific purpose like building a new hospital or fixing the roads. The money they pay you in return (with interest) is their way of thanking you for allowing them to use your money for a while.
Overall, bonds can be a great way for people to make some extra money and help out the companies, governments and cities we trust and rely on. Just remember, it's important to do your research and understand the risks involved before buying a bond from a company or government.
