Austroasiatic languages

The Austroasiatic languages, also known as Mon–Khmer, are a large language family in Mainland Southeast Asia and South Asia. These languages are scattered throughout parts of Thailand, India, Bangladesh, Nepal, and southern China and are the majority languages of Vietnam and Cambodia. There are around 117 million speakers of Austroasiatic languages. Of these languages, only Vietnamese, Khmer, and Mon have a long-established recorded history. Only two have official status as modern national languages: Vietnamese in Vietnam and Khmer in Cambodia. The Mon language is a recognized indigenous language in Myanmar and Thailand. In Myanmar, the Wa language is the de facto official language of Wa State. Santali is one of the 22 scheduled languages of India. The rest of the languages are spoken by minority groups and have no official status.
