Sansi language
The Sansi language, Sansiboli, or Bhilki, is a highly endangered Indo-Aryan language of the Central group. The language is spoken by the nomadic Sansi people of the Indian subcontinent.
Ethnologue sees it as part of Western Hindi. Some sources also mention it as a dialect of the Rajasthani language. Glottolog links it to Punjabi. Kabutra, spoken by a thousand people in Pakistan, is mutually intelligible.
