Pali is a special language used by Buddhist monks to write down important teachings and scriptures. It's kind of like a secret code that only they can read and understand. Just like how you learn how to read and write in school, the monks have to learn how to read and write in Pali so they can understand the teachings of Buddha. It's really important to them because it's like a special language that only they can use to learn about their religion. And just like how you have different words for different things, Pali has its own special words that mean certain things in Buddhism.
