Tosk Albanian is a language that some people speak in a country called Albania. It's similar to another Albanian language called Gheg Albanian, but the words and grammar are a little bit different.
Think of it like two different types of ice cream. Vanilla and chocolate ice cream are both yummy, but they taste a little bit different. Tosk Albanian and Gheg Albanian are both languages, but they sound a little bit different.
People who speak Tosk Albanian might use different words to say things than people who speak Gheg Albanian. For example, in English, we might say "hello" when we greet someone. In Tosk Albanian, they would say "tungjatjeta," but in Gheg Albanian, they would say "ç'kemi" instead!
Even though Tosk Albanian and Gheg Albanian might sound different, people who speak either language can still understand each other. It's kind of like how your friend might speak a little bit differently than you, but you can still talk to them and be friends!
