12. Nihali Language
2, 000 speakers
Nihali is marked as an “isolate” language, spoken within the regions of Maharashtra, Buldana and Jamod Jalgaon district, located in the western part of India. Among the five language families present in India, this language actually does not belong to any of them, and is considered to be quite unique. The people who speak it also belong to the tribe named Nihali, and they are mostly located in various places among several villages of this region. This is also one of the main reasons why it is really hard for this language to be preserved.
