Lechitic languages are a group of languages spoken in parts of Europe, mostly in Poland. Just like how there are different types of dogs, there are also different types of languages. Lechitic languages are a group of languages that are similar to each other, a bit like how Golden Retrievers and Labrador Retrievers are both types of dogs, but they are not exactly the same.
The Lechitic group includes two main languages: Polish and Kashubian. Polish is spoken by many people in Poland, which is a country in Europe. Kashubian, on the other hand, is spoken by a smaller group of people, mostly in a specific region in Poland called Kashubia.
What makes these languages Lechitic is that they come from the same family of languages. It's like how you might have cousins who are all part of the same family, but each one can be a little different from the others.
Some things that make Lechitic languages different from other languages include their unique sounds and their grammar rules. For example, in Polish, the word "dog" is "pies," but in Kashubian, it's "pieś." And in Polish, you might say "I went to the store," but in Kashubian, you would say "I to the store I went."
So, in summary, Lechitic languages are a group of similar languages spoken in Poland, and they have their own unique sounds and grammar rules.
