Malagasy is a language that people speak in Madagascar, which is an island country in Africa. Just like how people in some countries speak English and people in other countries speak French or Spanish, people in Madagascar speak Malagasy.
Now, Malagasy might sound a little bit different from the languages you've heard before, because it is what you call a "tonal language." That means that the meaning of a word can change depending on how you say it. For example, saying a word with a rising tone might mean one thing, while saying it with a falling tone might mean something completely different.
Another thing you might notice if you listen to Malagasy being spoken is that there are a lot of long vowel sounds. This means that some words might sound like they are being stretched out or sung, like the word "Malagasy" itself.
Malagasy is a really important language to the people of Madagascar because it is a part of their cultural heritage. It is also the official language of the country and is used in government, education, and media. Even though Malagasy might seem a little bit different from what you're used to hearing, it is a language that is really important to the people who speak it.
