Okay, kiddo, so let's start with some geography. Hungary is a country in Europe and Slovenia is another country that's right next to it. Sometimes, people who live in Slovenia but speak Hungarian are called Hungarian Slovenes.
Think of it like this - if you live in France but speak German, you're still French but you also speak another language. It's the same thing for Hungarian Slovenes - they live in Slovenia but they also speak Hungarian.
It's important to remember that just because someone speaks a different language, it doesn't mean they're from a different country. In fact, Hungarian Slovenes are Slovenian citizens and they're just a part of the larger Slovenian community.
Does that make sense, kiddo?
