503 speakers
This language, next in line on our list of critically endangered languages in India also belongs to the group of Sino-Tibetan language family, being Tibeto-Burman language, and it is spoken in the villages of Senapati district, which is a part of Manipur state. The members of the tribe that still use this language to some point are Christians. This language very much resembles Aimol, so the history of the language that was transmitted through the religious books is quite similar, though there is, unfortunately, a really small number of people who use this it today.
