A surname is a name that people use to identify their family. It's like a special word that only belongs to your family. So, let's say your family's surname is "Smith", and someone asks you what your last name is, you would say "Smith".
Now, Charla is a surname that some people have. It's a name that is passed down from generation to generation. This means that the children in a family get their last name from their parents, who got it from their parents, and so on. So, if your dad's last name is Charla, then your last name would be Charla too. And when you grow up and have children, they would also have the last name Charla.
Sometimes, people might wonder where surnames like Charla come from. Surnames can have different origins. They can be based on a person's occupation, like Smith, which comes from the word "blacksmith" who works with metal. Or they can be based on a person's appearance or a special trait, like "White" for someone with light-colored hair. Some surnames also come from a person's ancestors or the place they come from.
But for the specific surname Charla, I couldn't find enough information to give you a detailed explanation. It could have various origins or meanings depending on the family that has that surname.
