Corruption is when someone does something bad or dishonest to get something they want. For example, imagine you have a box of cookies and your friend really wants one. If your friend offers you some money or a toy to give them a cookie, that would be considered corruption. It doesn't matter if the cookie is small and doesn't seem very important, it's still not right to be dishonest or unfair. Corruption can happen in a lot of different situations, like when people are trying to get a job or win a competition, or even when someone is in charge of making important decisions for a country or a company. It's important to always be honest and fair, even if it means you don't get what you want right away.
