Varieties
Recognition of the different varieties of Ainu spoken throughout northern Japan and its surrounding islands in academia varies. (1990:9) and (1998:2) both speak of "Ainu languages" when comparing the varieties of language spoken in
Hokkaidō and Sakhalin; however, speaks only of "dialects". Refsing (1986) says Hokkaidō and Sakhalin Ainu were not
mutually intelligible

. (1964) considered Ainu data from 19 regions of Hokkaidō and Sakhalin, and found the primary division to lie between the two islands.
Hokkaidō Ainu
Hokkaidō Ainu clustered into several dialects with substantial differences between them: the 'neck' of the island (
Oshima County, data from and ); the "classical" Ainu of central Hokkaidō around and the southern coast ( and counties, data from and ; historical records from
Ishikari County and Sapporo show that these were similar); (on the southeastern cape in , but perhaps closest to the northeastern dialect); the northeast (data from and ); the north-central dialect (
Kamikawa County, data from and ) and (on the northwestern cape), which was closest of all Hokkaidō varieties to Sakhalin Ainu. Most texts and grammatical descriptions we have of Ainu cover the Central Hokkaidō dialect.
Kuril Ainu
Data on
Kuril Ainu is scarce, but it is thought to have been as divergent as Sakhalin and Hokkaidō.
Sakhalin Ainu
In
Sakhalin Ainu, an eastern coastal dialect of Taraika (near modern Gastello (
Poronaysk)) was quite divergent from the other localities. The Raychishka dialect, on the western coast near modern
Uglegorsk, is the best documented and has a dedicated grammatical description.
Take Asai, the last speaker of Sakhalin Ainu, died in 1994. The Sakhalin Ainu dialects had long vowels and a final -h phoneme, which was pronounced .
Scant data from Western voyages at the turn of the 19th–20th century ( 2000) suggest there was also great diversity in northern Sakhalin, which was not sampled by .

and the
Kurils.
The Ainu languages share a noteworthy amount of vocabulary (especially fish names) with several Northeast Asian languages, including
Nivkh,
Tungusic,
Mongolic, and
Chukotko-Kamchatkan. While linguistic evidence points to an origin of these words among the Ainu languages, its spread and how these words arrived into other languages will possibly remain a mystery.
The most frequent proposals for relatives of Ainu are given below:
Altaic
John C. Street (1962) proposed linking Ainu,
Korean, and
Japanese in one family and
Turkic,
Mongolic, and
Tungusic in another, with the two families linked in a common "North Asiatic" family. Street's grouping was an extension of the
Altaic hypothesis, which at the time linked Turkic, Mongolic, and Tungusic, sometimes adding Korean; today Altaic sometimes includes Korean and rarely Japanese but not Ainu (Georg et al. 1999).
From a perspective more centered on Ainu, James Patrie (1982) adopted the same grouping, namely Ainu–Korean–Japanese and Turkic–Mongolic–Tungusic, with these two families linked in a common family, as in Street's "North Asiatic".
Joseph Greenberg
Joseph Harold Greenberg (May 28, 1915 – May 7, 2001) was an American linguist, known mainly for his work concerning linguistic typology and the genetic classification of languages.

(2000–2002) likewise classified Ainu with Korean and Japanese. He regarded "Korean–Japanese-Ainu" as forming a branch of his proposed
Eurasiatic language family. Greenberg did not hold Korean–Japanese–Ainu to have an especially close relationship with Turkic–Mongolic–Tungusic within this family.
The Altaic hypothesis is now rejected by the scholarly mainstream.
Austroasiatic
Shafer (1965) presented evidence suggesting a distant connection with the
Austroasiatic languages
The Austroasiatic languages ( ) are a large language family spoken throughout Mainland Southeast Asia, South Asia and East Asia. These languages are natively spoken by the majority of the population in Vietnam and Cambodia, and by minority popu ...
, which include many of the indigenous languages of Southeast Asia. presented his reconstruction of Proto-Ainu with evidence, in the form of proposed sound changes and cognates, of a relationship with Austroasiatic. In , he still regarded this hypothesis as preliminary.
Language contact with the Nivkhs
The Ainu appear to have experienced intensive contact with the
Nivkhs during the course of their history. It is not known to what extent this has affected the language. Linguists believe the vocabulary shared between Ainu and
Nivkh (historically spoken in the northern half of Sakhalin and on the Asian mainland facing it) is due to
borrowing.
Language contact with the Japanese
The Ainu came into extensive contact with the Japanese in the 14th century. Analytic grammatical constructions acquired or transformed in Ainu were probably due to contact with the Japanese language. A large number of Japanese loanwords were borrowed into Ainu and to a smaller extent vice versa. There are also a great number of

A loanword (also a loan word, loan-word) is a word at least partly assimilated from one language (the donor language) into another language (the recipient or target language), through the process of borrowing. Borrowing is a metaphorical term t ...
s from the Japanese language in various stages of its development to Hokkaidō Ainu, and a smaller number of loanwords from Ainu into Japanese, particularly animal names such as (猟虎, 'sea otter'; Ainu ), (馴鹿, 'reindeer'; Ainu ), and (柳葉魚, a fish, ''Spirinchus lanceolatus''; Ainu ). Due to the low status of Ainu in Japan, many ancient loanwords may be ignored or undetected, but there is evidence of an older substrate, where older Japanese words which have no clear etymology appear related to Ainu words which do. An example is modern Japanese or (鮭), meaning 'salmon', probably from the Ainu or for 'salmon', literally 'summer food'.
According to P. Elmer (2019), the Ainu languages are a

Other proposals

, based on racial theories regarding the origin of the Ainu people. The theory of an Indo-European—Ainu relation was popular until 1960; later linguists dismissed it and concentrated on more local language families.
Tambovtsev (2008) proposes that Ainu is typologically most similar to Native American languages and suggests that further research is needed to establish a genetic relationship between these languages.
Geography
Until the 20th century, Ainu languages were spoken throughout the southern half of the island of
Sakhalin and by small numbers of people in the Kuril Islands. Only the Hokkaido variant survives, with the last speaker of Sakhalin Ainu having died in 1994.

Ainu on mainland Japan

It is occasionally suggested that Ainu was the language of the indigenous people of the northern part of the main Japanese island of Honshu. The main evidence for this is the presence of
place names

that appear to be of Ainu origin in both locations. For example, the common to many northern Japanese place names is known to derive from the Ainu word ("river") in Hokkaidō, and the same is suspected of similar names ending in in northern Honshū and , such as the and rivers in
Toyama Prefecture. Other place names in and , such as
Mount Ashigara (), (modern Tokyo),
Keta Shrine (), and the
Noto Peninsula, have no explanation in Japanese, but do in Ainu. The traditional hunters of the mountain forests of retain Ainu words in their hunting vocabulary (see
Matagi dialect). However, Elmer (2019) has also suggested Japonic etymologies, which supposedly got borrowed into early Ainu and lost in contemporary Japonic dialects.
The direction of influence and migration is debated. It has been proposed that at least some Jōmon period groups spoke a proto-Ainu language, and that they displaced the
Okhotsk culture north from southern Hokkaido when the Ainu fled Japanese expansion into northern Honshu, with the Okhotsk ancestral to the modern
Nivkh as well as a component of the modern Ainu. However, it has also been proposed that the Ainu themselves can be identified with the Okhotsk culture, and that they expanded south into northern Honshu as well as to the

or that the Emishi spoke a Japonic language, most closely related to ancient
Izumo dialect, rather than anything related to Ainu, with Ainu-speakers migrating later from Hokkaido to northern Tōhoku. The purported evidence for this are old-Japanese loanwords in the Ainu language, including basic vocabulary, as well as distinctive Japonic terms and toponyms found in Tōhoku and Hokkaido, that have been linked to the Izumo dialect.
