Okay kiddo, in the United Kingdom, some people have special titles that show respect to them. These special titles are called "courtesy titles". They are usually given to people who are part of a royal or noble family, like a prince or a duchess.
When someone is given a courtesy title, it means that they are respected and important. They might have more privileges than other people, like being able to go to special events or having a special seat at a ceremony.
You might have heard some of these courtesy titles before, like "Prince" or "Duke" or "Earl". These titles are passed down from generation to generation, and they usually come with land and wealth too. So, if someone is a Duke, they might own a big estate with lots of farms and houses.
But not everyone in the UK has a courtesy title. In fact, most people don't. So, it's important to treat everyone with respect, regardless of their title or position in society.
In summary, courtesy titles are special titles given to important people in the UK, usually those from a royal or noble family. They are a sign of respect and may come with certain privileges, but it's still important to treat everyone with respect.
