The Aragonese language is a way of talking that some people from a place called Aragon in Spain use. Just like how you might speak English, someone from Aragon might use this language to talk to their friends, family, and people around them.
It's kind of like a secret code, that only people from Aragon know how to speak! Some words in Aragonese might sound the same as words in Spanish or English, but a lot of the words will be different.
For example, instead of saying "hello" like we do in English, someone speaking Aragonese might say "chueca". And instead of saying "goodbye", they might say "adeu".
It's really cool that there are different languages all over the world that people use to communicate with each other!
