Okay, so imagine you're playing with your friends and you make a rule that says nobody can say mean things to each other. That's sort of like what parliamentary privilege is. It's a rule that lets people who work in the government say what they want, without being punished for it like we might be if we broke a rule we made with our friends.
So what exactly is parliamentary privilege? Well, it's a special protection that people who work in the government get. This includes people like Members of Parliament, Senators, and other people who work in the government. When they're in Parliament or doing things related to their job, they're allowed to say whatever they want, without getting in trouble for it.
This means that if a Member of Parliament wanted to say something about someone else in the government that might be embarrassing, they wouldn't get in trouble for it. They could say it without worrying about being sued or getting into trouble with the law.
Now, this doesn't mean that people who work in the government can just say whatever they want all the time. They can only use parliamentary privilege when they're doing their job. So if a Member of Parliament went out into the street and started talking about someone they didn't like, they wouldn't be protected by parliamentary privilege.
So that's basically what parliamentary privilege is. It's a special rule that lets people who work for the government say what they want, without getting in trouble for it.
