Alright kiddo, Serbian names are a little bit different from what you might be used to. In Serbia, people usually have three parts to their name: first name, middle name and last name.
The first name is just like what you have. It's the name that your parents gave you like Emma or Jacob.
The middle name is a little different. It's usually the name of your father or your mother's father. So let's say your name is Emma and your dad's name is John. Your middle name would be John. But if your mom's dad was named George, your middle name could be George too.
The last name is also different from what you might be used to. In Serbia, last names depend on the gender of the person. If you are a boy, your last name ends with "-ić". If you are a girl, your last name ends with "-ić" but with an "a" instead of just "ić". For example, if your name is Ana and your last name is Petrović, your brother's last name would also be Petrović but without the "a" at the end.
Sometimes, Serbian last names are based on where your family came from or what they did for work. For example, one Serbian last name is "Kovačević", which means someone who comes from a family of blacksmiths.
So there you have it kiddo, that's a little bit about Serbian names!
