15. Baghati Language
3, 976 speakers
Baghati language is actually a dialect of Mahasu Pahari language, and it is spoken in Himachal Pradesh, Northern India. The number of speakers is almost near 4,000, this may be a little confusing, since it does not look critically endangered. On the other side, if you take into consideration that these speakers are between 60 and 90 years old, they do not speak the language perfectly, and did not transmit it to their children or grandchildren–you will realize that maybe in 20 years from now this language will be extinct and there will be nothing to do about it.
