Here are some important points to understand:
* Diversity: India is home to over 700 different languages, with many spoken by Adivasi communities.
* No single language: It's like asking what language all Europeans speak - there's no single answer.
* Tribal languages: Many Adivasi languages belong to families like Austroasiatic, Dravidian, and Tibeto-Burman.
* Endangered languages: Sadly, many Adivasi languages are endangered due to factors like migration, urbanization, and the dominance of larger languages.
