Nivkh languages

Nivkh ( NEEFK; occasionally also Nivkhic; self-designation: Нивхгу диф, Nivhgu dif, /ɲivxɡu dif/), Gilyak ( GIL-yak), or Amuric, is a small language family, often portrayed as a language isolate, of two or three mutually unintelligible languages spoken by the Nivkh people in Outer Manchuria, in the basin of the Amgun (a tributary of the Amur), along the lower reaches of the Amur itself, and on the northern half of Sakhalin. "Gilyak" is the Russian rendering of terms derived from the Tungusic "Gileke" and Manchu-Chinese "Gilemi" (Gilimi, Gilyami) for culturally similar peoples of the Amur River region, and was applied principally to the Nivkh in Western literature. The population of ethnic Nivkhs has been reasonably stable over the past century, with 4,549 Nivkhs counted in 1897 and 4,673 in 1989. However, the number of native speakers of the Nivkh language among these dropped from 100% to 23.3% in the same period, so by the 1989 census there were only 1,079 first-language speakers left. That may have been an overcount, however, as the 2010 census recorded only 198 native speakers, less than 4% of the ethnic population. Proto-Nivkh(ic), the proto-language ancestral to the modern-day languages, has been reconstructed by Fortescue (2016).
