Thaana is a special way of writing the language of the Maldives, a country made up of islands in the Indian Ocean. Imagine that you have a special code or alphabet that you use to write messages to your friends. Thaana is like that, but it only has 24 letters! The letters look a little bit like squiggles and circles, but people who grew up in the Maldives can easily understand them. It's like a secret code that only they know. So if you ever visit the Maldives or want to write a message to someone who speaks their language, you might see these squiggles and circles and know that it's written in Thaana!
