Southern Khanty language
Southern Khanty is a Uralic language, frequently considered a dialect of a unified Khanty language, spoken by 56 people in 2010. It is considered to be extinct, its speakers having shifted starting in the 18th century to Russian or Siberian Tatar, but some speakers of the Kyshikov or Ust-Nazym dialect were found in its former territory. Speakers of Surgut Khanty have moved into the former territory of the Demyanka dialect. It was transitional between the Northern Khanty and Eastern Khanty dialect groups, but it is now a distinct language.
