13. Aimol Language
2, 643 speakers
This is the language that is mostly spoken in Manipur, which is located in northeastern India, and the people who speak it are also called Aimol people. They are predominantly Christians, and what is really interesting is the fact that they translated the New Testament in Aimol, believing that it will help spread the religion, but also preserve the language. However, with a little bit fewer than 3,000 speakers, this language is also critically endangered, considering the fact its speakers are older people.
