Extent of Yukaghir languages in the 17th (hatched) and 20th (solid) centuries | |
The Yukaghir languages (/ˈjuːkəɡɪər/ YOO-kə-geer or /juːkəˈɡɪər/ yoo-kə-GEER; also Yukagir, Jukagir) are a small family of two closely related surviving languages—Tundra and Kolyma Yukaghir—spoken by the Yukaghir in the Russian Far East living in the basin of the Kolyma River. Estimates of the number of speakers in the 21st century range from several dozen to about 500 (see below for details). The entire family, as such, is regarded as moribund.
Tundra and Kolyma Yukaghir are the only two remnants of what used to be one of the dominant languages (or language families) of northeastern Siberia, spreading from the River Anadyr in the east to the River Lena in the west. On the basis of the evidence of early sources, it can be assumed that there existed a Yukaghir dialect continuum, with what is today Tundra Yukaghir and Kolyma Yukaghir at the extremes.
The Yukaghir have experienced a language shift since the early 20th century, with a majority of speakers also speaking Russian and Yakut. In 1993, Juha Janhunen estimated the number of speakers for each Yukaghir language to be less than 50, although the number of persons reporting their Yukaghir ethnicity may be substantially higher. The number of Yukaghir speakers fell from 604 in the 2002 Russian census to 516 who reported speaking it as their native language in 2020–2021.
The two extant varieties of Yukaghir are:

Extinct varieties include Omok and Chuvan, which survived until the 19th century.
The two Yukaghir languages share only a relatively small part of the vocabulary and are not mutually intelligible. The basic grammatical structures, however, are very similar. Both languages have residual vowel harmony and a complex phonotactics of consonants. Both have rich agglutinative morphology and are strictly head-final. There is practically no finite subordination and very few coordinate structures. The most spectacular feature of TY and KY grammar is the split intransitive alignment system based on discourse-pragmatic features. In the absence of narrow focus, the system is organised on the nominative–accusative basis; when focused, direct objects and subjects of intransitive verbs are co-aligned (special focus case, special focus agreement).

English translation:
All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood.
The relationship of the Yukaghir languages with other language families is uncertain, though it has been suggested that they are distantly related to the Uralic languages, thus forming the putative Uralic–Yukaghir language family.
Michael Fortescue argued that Yukaghir is related to the Eskimo-Aleut languages along with Uralic languages, forming the Uralo-Siberian language family.
