So just like how your teacher or mom can speak up for what they think is right, the Advocate General for Scotland is someone in Scotland's government who helps speak up for what they think is right in the law.
They help make sure people follow the rules and laws properly in Scotland. They also help the Scottish government make good decisions about the laws they create and make sure they're fair for everyone.
It's like having a smart and super helpful friend who helps you make good decisions and stand up for what you believe in.
