Ural-Altaic, Uralo-Altaic, Uraltaic, or Turanic is a linguistic convergence zone and abandoned language-family proposal uniting the Uralic and the Altaic languages. It is generally now agreed that even the Altaic languages do not share a common descent: the similarities among Turkic, Mongolic and Tungusic are better explained by diffusion and borrowing. Just as Altaic, internal structure of the Uralic family also has been debated since the family was first proposed. Doubts about the validity of most or all of the proposed higher-order Uralic branchings are becoming more common. The term continues to be used for the central Eurasian typological, grammatical and lexical convergence zone.
The Eskaleut, Eskimo–Aleut or Inuit–Yupik–Unangan languages are a language family native to the northern portions of the North American continent, and a small part of northeastern Asia. Languages in the family are indigenous to parts of what are now the United States (Alaska); Canada including Nunavut, Northwest Territories, northern Quebec (Nunavik), and northern Labrador (Nunatsiavut); Greenland; and the Russian Far East. The language family is also known as Eskaleutian, Eskaleutic or Inuit–Yupik–Unangan.
Nivkh, or Gilyak, 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 Russian Manchuria, in the basin of the Amgun, 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" for culturally similar peoples of the Amur River region, and was applied principally to the Nivkh in Western literature.
The Paleo-Siberian languages are several language isolates and small language families spoken in parts of Siberia. They are not known to have any genetic relationship to each other; their only common link is that they are held to have antedated the more dominant languages, particularly Tungusic and latterly Turkic languages, that have largely displaced them. Even more recently, Turkic and especially Tungusic have been displaced in their turn by Russian.
The Chukotko-Kamchatkan or Chukchi–Kamchatkan languages are a language family of extreme northeastern Siberia. Its speakers traditionally were indigenous hunter-gatherers and reindeer-herders. Chukotko-Kamchatkan is endangered. The Kamchatkan branch is moribund, represented only by Western Itelmen, with only 4 or 5 elderly speakers left. The Chukotkan branch had close to 7,000 speakers left, with a reported total ethnic population of 25,000.
The Nivkh, or Gilyak, are an Indigenous ethnic group inhabiting the northern half of Sakhalin Island and the lower Amur River and coast on the adjacent Russian mainland. Historically, they may have inhabited parts of Manchuria.
Eurasiatic is a proposed language macrofamily that would include many language families historically spoken in northern, western, and southern Eurasia.
Uralo-Siberian is a hypothetical language family consisting of Uralic, Yukaghir, and Eskaleut. It was proposed in 1998 by Michael Fortescue, an expert in Eskaleut and Chukotko-Kamchatkan, in his book Language Relations across Bering Strait. Some have attempted to include Nivkh in Uralo-Siberian. Until 2011, it also included Chukotko-Kamchatkan. However, after 2011 Fortescue only included Uralic, Yukaghir and Eskaleut in the theory, although he argued that Uralo-Siberian languages have influenced Chukotko-Kamchatkan.
Itelmen or Western Itelmen, formerly known as Western Kamchadal, is a language of the Chukotko-Kamchatkan family spoken on the western coast of the Kamchatka Peninsula. Fewer than a hundred native speakers, mostly elderly, in a few settlements in the southwest of Koryak Autonomous Okrug, remained in 1993. The 2021 Census counted 2,596 ethnic Itelmens, virtually all of whom are now monolingual in Russian. However, there are attempts to revive the language, and it is being taught in a number of schools in the region.
Geographically, Siberia includes the Russian Urals, Siberian, and Far Eastern Federal Districts.
Borean is a hypothetical linguistic macrofamily that encompasses almost all language families worldwide except those native to the Americas, Africa, Oceania, and the Andaman Islands. Its supporters propose that the various languages spoken in Eurasia and adjacent regions have a genealogical relationship, and ultimately descend from languages spoken during the Upper Paleolithic in the millennia following the Last Glacial Maximum. The name Borean is based on the Greek βορέας, and means "northern". This reflects the fact that the group is held to include most language families native to the northern hemisphere. Two distinct models of Borean exist: that of Harold C. Fleming and that of Sergei Starostin.
Mosan is a hypothetical language family consisting of the Salishan, Wakashan, and Chimakuan languages of the Pacific Northwest region of North America. It was proposed by Edward Sapir in 1929 in the Encyclopædia Britannica. Little evidence has been adduced in favor of such a grouping, no progress has been made in reconstructing it, and it is now thought to reflect a language area rather than a genetic relationship. The term persists outside academic linguistic literature because of Sapir's stature.
Algonquian–Wakashan is a hypothetical language family composed of several established language families that was proposed in 1929. The proposal consists of the following:
Chukotkan is a dialect cluster that forms one branch of the Chukotko-Kamchatkan language family. It is spoken in two autonomous regions at the extreme northeast of Russia, bounded on the east by the Pacific and on the north by the Arctic.
Kamchatkan (Kamchatic) is a former dialect cluster spoken on the Kamchatka Peninsula. It now consists of a single language, Western Itelmen. It had 100 or fewer speakers in 1991, mostly of the older generation. The Russian census of 2010 still reported 80 speakers.
Michael David Fortescue is a British-born linguist specializing in Arctic and native North American languages, including Kalaallisut, Inuktun, Chukchi and Nitinaht.
Proto-Chukotko-Kamchatkan is the reconstructed common ancestor of the Chukotko-Kamchatkan languages. It is purported to have broken up into the Northern (Chukotian) and Southern (Itelmen) branches around 2000 BCE, when western reindeer herders moved into the Chukotko-Kamchatkans' homeland and its inland people adopted the new lifestyle.
The Eskimo–Uralic hypothesis posits that the Uralic and Eskimo–Aleut language families belong to a common macrofamily. It is not generally accepted by linguists because the similarities can also be merely areal features, common to unrelated language families. In 1818, the Danish linguist Rasmus Rask grouped together the languages of Greenlandic and Finnish. The Eskimo–Uralic hypothesis was put forward by Knut Bergsland in 1959. Ante Aikio stated that it's possible that there exists some connection between the two families, but exact conclusions can't be drawn and the similarities could exist by loaning.
The Ainu languages, sometimes known as Ainuic, are a small language family, often regarded as a language isolate, historically spoken by the Ainu people of northern Japan and neighboring islands.
