3. Shompen Language
100 speakers
With 100 speakers of the next language on our list of critically endangered languages in India, there are many ambiguities regarding this language. It is supposed to belong to Austroasiatic group of languages, but there are also two dialects, Kalay and Keyet. The population of the Shompen people is located around the Great Nicobar Islands, but not all of the members speak the language, which is one of the main reasons it is critically endangered. The other language they speak is regarded to be completely unrelated to Shompen, which also contributed to the fact its condition is very critical.
