In Thailand, they have a special way of naming important people. It's like a special nickname that shows how important they are. The people who get these nicknames are usually part of the Royal Family, which is kind of like a big family of very important people.
The most important person in the Royal Family is the King or Queen. They have a special name that means "The Great." Their nickname is "Chakravartin," which is a really big and fancy word that means "Ruler of the World."
Next, there are princes and princesses. Princes are the sons of the King and Queen, and princesses are their daughters. They get different nicknames based on how important they are.
Some of the princesses are called "Chao Fa," which means "Lady Prince." That's because they are very important, like a prince.
The princes have different nicknames too. The ones who are sons of the King and Queen are called "Chao Fah," which means "Prince Prince." They are extra important because they might become King one day.
Some of the other princes get nicknames based on where they come from or what they do. For example, one prince is called "Chao Phraya," which means "Prince of the Big River." That's because he is in charge of a big river in Thailand.
There are also people in the Royal Family who are not princes or princesses. They get different nicknames too.
Some of the people who work for the King or Queen are called "Phra Ong Chao." That means "Lord of Lords," which is a really fancy nickname that shows how important they are in the Royal Family.
Other important people get different nicknames. For example, there is one person who is called "Mom Rajawongse." That means "Honorary Prince." He is very important, so he gets a special nickname that shows that he is almost like a prince.
So, in Thailand, important people get special nicknames called Royal Ranks and Titles. These nicknames show how important they are in the Royal Family. The King and Queen are the most important, and princes and princesses are also very important. Other people who work for the Royal Family or are related to them get different nicknames too.
