Sampa is a way of writing the sounds of a language using special symbols. It's like a secret code that only some people know how to read. Just like how you learn your ABCs in school, some grown-ups learn how to read and write Sampa. It helps them understand how to pronounce words correctly and communicate with people who speak different languages. Kind of like how you use pictures to help you remember words, Sampa uses symbols to help grown-ups remember sounds. It's pretty cool!
