Kochila Tharu

Kochila Tharu, also called Morangiya, Septari or Saptariya Tharu, Madhya-Purbiya Tharu, and Mid-Eastern Tharu, is a diverse group of language varieties in the Tharu group of the Indo-Aryan languages. The several names of the varieties refer to the regions where they dominate. It is one of the largest subgroupings of Tharu. It is spoken mainly in Nepal with approximately 250,000 speakers as of 2003. In addition to language, cultural markers around attire and customs connect individuals into the ethnic identity Kochila.

Heavily concentrated in the eastern area of Terai, speakers of Kochila Tharu live in linguistically diverse regions and are generally multilingual (with the exception of some elderly female speakers). The language is widely utilized by all members of the community and coexists with the use of Nepali.

Kochila Tharu communities are not found in isolation, but live in districts intermixed with speakers of other languages. Kochila Tharu have superficial similarities with neighbouring languages such as Bhojpuri, Maithili, Bengali and Rajbanshi due to their close proximity with these various ethnicities depending upon the districts that they are present.

A 2013 survey by SIL International found that the language was being taught to children as their first language and used conversationally between multiple generations of speakers, characteristics of a "vigorous" language as defined by Ethnologue Expanded Graded Intergenerational Disruption Scale (EGIDS).
