Okay kiddo, Burgenland Croatian is a special way of speaking Croatian. It's spoken in a place called Burgenland which is in Austria, but right next to Croatia. People there have been speaking Croatian for a very long time, but they also have their own special way of saying things. It's like if you and your friends have a secret language that only you understand. Burgenland Croatian is like that, but for grown-ups. People who speak Burgenland Croatian might still understand regular Croatian, but they use their own special words and pronunciations when they talk to each other.
