Bulgarian is a language that people speak in Bulgaria. It is their official language, just like how English is the official language in some countries. When you learn Bulgarian, you can talk to people who live in Bulgaria.
The Bulgarian language uses a special alphabet called Cyrillic. This alphabet is different from the English alphabet because it has different letters that make different sounds. So when you learn Bulgarian, you have to learn a new way of reading and writing.
When you talk in Bulgarian, words have different endings depending on who is speaking and who they are speaking to. For example, if you are talking to your friend, you would use a different word ending than if you were talking to your grandpa. This shows respect for the person you are talking to.
Overall, learning Bulgarian can be challenging because it has a different alphabet and grammar rules than English. But it allows you to connect with people from Bulgaria and understand their culture better.
