162. Sakhalin and Kuril Ainu: The External Comparison
How do the three Ainu varieties—Hokkaido, Sakhalin, and Kuril—differ and relate to each other?
In Sakhalin Ainu, /h/ regularly changes to /s/ following /i/. (Alonso de la Fuente 2022: 5.1) In vowel correspondence between Hokkaido and Sakhalin Ainu, identical vowels correspond in most cases. (Itabashi 2001)
Ainuic: three varieties, two branches
How many varieties constitute the Ainuic family and what is their genetic relationship?
Hokkaido Ainu and Sakhalin Ainu varieties lack mutual intelligibility in conversation. (Murasaki 2025, Refsing 1986: 52; reported in Bugaeva 2012) According to Shirō Hattori, a major linguistic rift exists between the Hokkaido and Sakhalin dialects of Ainu. (reported in Nakagawa 2024: 105, Shibatani 1990: 6) Most of the innovations characteristic of West Coast Sakhalin Ainu are less conspicuous in East Coast Sakhalin varieties. (reported in Bugaeva 2016) In the internal diversification of the Ainu language family, Sakhalin Ainu was the first branch to separate (approximately 800 years ago), followed by Northern Kuril Ainu less than 600 years ago. (Janhunen 2022: 2.3) John Batchelor and Bronisław Piłsudski were able to converse with each other using Yezo (Hokkaido) Ainu and Sakhalin Ainu respectively. (reported in Majewicz 2022: 4.4) The Raichishka, Huroochi, and Esutori dialects on the west coast of Sakhalin are almost the same dialect. (reported in Murasaki 2025: 112) Between the Raichishka dialect and the Maoka dialect of Sakhalin Ainu, mutual intelligibility reaches about 99 percent despite slight differences. (Murasaki 2025: 112) The dialect differences among Sakhalin Ainu speakers from Taraika, Raichishka, and Maoka posed no barrier to communication. (Murasaki 2025: 112) Sakhalin Ainu is a dialect that originally branched off from Hokkaido Ainu. (Murasaki 2025: 115) The differences between the Hokkaido and Sakhalin dialects of Ainu are considerable. (Refsing 1986) Paralleling the original regions of Ainu habitation, three large dialect groups are recognized: the Kuril group, the Sakhalin group, and the Hokkaido group. (Shibatani 1990: 6) Among the Sakhalin group, the eastern coastal dialect of Taraika is said to be markedly different from the speech of other areas. (reported in Shibatani 1990: 6) The Raychishka dialect is a representative west coast Sakhalin dialect. (Shibatani 1990: 6) Karafuto Ainu belongs to the c- dialects in the word-initial p/c opposition. (Tangiku 2022: 9.1)
The prosodic correspondence: length and pitch
How do Sakhalin vowel length and Hokkaido pitch accent correspond?
In Hokkaido Ainu, the word for 'delicious' is kera'an, corresponding to Sakhalin keera'an. (Murasaki 2025: 47, 64) In Hokkaido Ainu, the word for 'child' is po (corresponding to Sakhalin poo). (Murasaki 2025: 53, 67) In modern Sakhalin Ainu dialects, an independent (C)V morpheme is phonologically (C)VV and always pronounced long, both independently and as a constituent of a compound. (Bugaeva 2022: 3.5) A Hokkaido Ainu form with an accented first syllable (C)VCV(C) generally corresponds to (C)VVCV(C) with a long vowel in Sakhalin Ainu (e.g. Hokkaido réra vs. Sakhalin reera 'wind'). (reported in Bugaeva 2022: 3.5) In Sakhalin Ainu, long vowels in independent words alternate with short vowels in compounds, as in nii 'tree' versus 'ah-ni 'Manchurian elm'. (Bugaeva 2022: 3.5) In Sakhalin Ainu, when a stem beginning with /'V/ follows a CVV stem, the compound surfaces as CV'V rather than *CVV'V (e.g. kaa + 'ama -> ka'ama 'to set a snare'). (reported in Bugaeva 2022: 3.5) In words containing a high-pitched CVC syllable in Hokkaido Ainu where the coda is /r/, the corresponding syllable in Sakhalin Ainu becomes open by taking a following vowel, which is always short and low-pitched. (proposed in Itabashi 2001) In the case of monosyllabic CVC words with coda /r/ in Hokkaido Ainu, pitch shifts to the second syllable in the corresponding Sakhalin Ainu CVC*V form in accordance with accent rules. (Itabashi 2001) When a Hokkaido Ainu word contains a low-pitched CVC syllable where the coda consonant is /p, t, k, s, m, n, w, y/, the corresponding syllable in Sakhalin Ainu is always closed, with a short vowel and low pitch. (proposed in Itabashi 2001) When a Hokkaido Ainu word contains a low-pitched CVC syllable where the coda consonant is /r/, the corresponding Sakhalin Ainu word has a long vowel with high pitch in the first syllable, and the /r/-coda syllable takes a following vowel to become open with a short, high-pitched vowel. (proposed in Itabashi 2001) When Hokkaido Ainu has two adjacent closed syllables (where the pitch of the first closed syllable is always high), in the corresponding Sakhalin Ainu word the vowel of the first syllable is always short and high-pitched. (proposed in Itabashi 2001) The word for 'year' is pa in Hokkaido Ainu (corresponding to Sakhalin paa). (Murasaki 2025: 52) In Sakhalin Ainu, there is a phonemic contrast between short vowels (V) and long vowels (VV), yielding the syllable template (C)V{(V)|(C)}. (Nakagawa 2024: 42) In Sakhalin Ainu, free words of the shape V or CV with a short vowel do not exist, and such monosyllabic short forms only appear bound as affixes to other words. (Nakagawa 2024: 43) In Sakhalin Ainu, although there is no accent contrast, vowel length corresponds to a considerable degree to pitch accent in Hokkaido Ainu. (Nakagawa 2024: 49)
Final-consonant debuccalization in Sakhalin
How do Sakhalin varieties treat Hokkaido's final obstruents /p, t, k/, /m/, and /r/?
In Sakhalin Ainu, Proto-Ainu final consonants */p/, */t/, and */k/ underwent debuccalization, moving their place of articulation to the glottis. (Alonso de la Fuente 2022: 5.1) Syllable-final stops /p, t, k/ in Hokkaido Ainu correspond to syllable-final fricative /h/ in Sakhalin Ainu. (Itabashi 2001) When the vowel preceding syllable-final stops is /u/ in Hokkaido Ainu, Sakhalin Ainu sometimes has /h/ (transcribed as [f]). (Itabashi 2001) When the vowel /i/ immediately precedes syllable-final stops in Hokkaido Ainu, Sakhalin Ainu corresponds with /s/. (Itabashi 2001) Geminate stops /pp, tt, kk/ in Hokkaido Ainu correspond to velar fricative combinations /hp, ht, hk/ in Sakhalin Ainu, which lacks geminates. (Itabashi 2001) The fricative [x] (or [ç] when following i) exists only in Sakhalin Ainu, corresponding to Hokkaido syllable-final k, t, p, sh, and r. (Kindaichi & Chiri 1936) Syllables ending in /p, t, k/ in Hokkaido Ainu correspond to /h/ or /s/ in Sakhalin Ainu. (Nakagawa 2024: 27) When a syllable-final stop of Hokkaido Ainu corresponds to /h/ or /s/ in Sakhalin Ainu, it becomes /h/ after vowels /a, u, e, o/, but can become /s/ when the preceding vowel is /i/. (Nakagawa 2024: 27) In Sakhalin Ainu, phonemes corresponding to Hokkaido Ainu coda -p, -t, and -k regularly become -h, though the Taraika dialect is reported to pronounce them as -p, -t, and -k. (Nakagawa 2024: 46) In Sakhalin Ainu, coda -c and -r do not exist, and segments corresponding to Hokkaido coda -r correspond to -rV or -h. (Nakagawa 2024: 46) In Sakhalin Ainu, codas corresponding to Hokkaido -ip, -it, -ik are generally pronounced as [iç] and transcribed as -is (or sometimes -ih), though whether phonemically /-ih/ or an alternation /h/ → /s/ is debated. (Nakagawa 2024: 46) In dialects such as the Taraika dialect, conversion of a syllable-final consonant to -h does not take place. (reported in Tangiku 2022: 9.2)
The affiliative and the underlying base consonant
How does the affixation of the possessive suffix in Sakhalin reveal the underlying base consonant?
In Sakhalin Ainu, when a vowel follows, original final consonants resurface and take the same form as in Hokkaido Ainu. (Kindaichi & Chiri 1936)
Morphological and lexical divergences
What are the main morphological and lexical differences between Hokkaido and Sakhalin Ainu?
In Hokkaido Ainu, 'iku means 'to drink alcohol'. (Murasaki 2025: 45, 69) Sakhalin Ainu uses the endonym 'enciw instead of 'áynu. (Janhunen 2022: 2.2) The archaic word 'enciw meaning 'human' is preserved in the elderly register of Sakhalin Ainu. (Murasaki 2025) The Taraika dialect, spoken on the northernmost east coast of Sakhalin, retains older forms than the west coast dialects, such as in person affixes and syllable-final consonants. (Murasaki 2025: 112) The jaw harp called mukkuri in Hokkaido is called muhkun in Sakhalin. (Murasaki 2025: 115) Sakhalin dialects (especially the Raichishka dialect on the west coast) differ substantially both lexically and grammatically from the dialects of Hokkaido. (Nakagawa 2024: 16) The greeting iyankarahte 'hello' recorded from a woman from Sakaehama on the east coast of Sakhalin corresponds to Hokkaido irankarapte and west coast Sakhalin irankarahte. (Nakagawa 2024: 79) In the Sakhalin dialect, especially when narrating tales, manu is frequently placed at the end of each sentence to indicate that the story is based on hearsay. (Nakagawa 2024: 310) The Sakhalin Raychishka dialect has both uses of ranke as found in Hokkaido, as well as its function as a distributive postposition. (reported in Refsing 1986: 246) In the Sakhalin Raychishka dialect, a conjunctionalizer teh similar to tek is found. (reported in Refsing 1986: 246) In the Sakhalin Raychishka dialect, yayne indicates that the second predicate occurs after the first has been going on for some time, without implying any nuance of impatience. (reported in Refsing 1986: 248) The conjunctional suffix kanne in the Sakhalin Raychishka dialect is similar in meaning to Shizunai kane. (reported in Refsing 1986: 251) The Ainu word sinjitsu 'origin' recorded from a Sirunkur speaker is cognate with and phonologically closer to Taraika dialect sincit [ʃinʤit] 'root' than to Raichiska dialect sinris on the west coast. (reported in Shiraishi & Tangiku 2022: 7.2) In Karafuto dialects, basic vocabulary for family relations, verbs, and numerals differs from Hokkaido dialects, such as ahci 'grandmother', henke 'grandfather', unci 'fire', hukuy 'burn', and etaras 'stand'. (Tangiku 2022: 9.3) In Karafuto Ainu, lexical variation exists between age groups, where younger speakers use one set of words and mature adults use an elders' vocabulary. (reported in Tangiku 2022: 9.3) The verb meaning 'to be awake' is attested as monak in Hokkaido Ainu and as moonah or monax in Sakhalin Ainu. (Vovin 2022: 6.4)
Person affixes and plural marking
How do person affixes and plural marking differ between Hokkaido and Sakhalin Ainu?
Sakhalin (a)hci can be analyzed as an auxiliary verb by the same diagnostic, and is likely etymologically related to Hokkaido ci. (proposed in Nakagawa 2024: 156) In both East and West Coast Sakhalin dialects, ci= is barely used, and when it does appear, it means 'I' rather than first-person plural exclusive. (Nakagawa 2024: 181) In Sakhalin dialects, an= fills the first-person plural slot and expresses 'we' regardless of whether the hearer is included. (Nakagawa 2024: 181) In Sakhalin Ainu, an= is also frequently used to refer to the speaker ('I'). (Nakagawa 2024: 181)
The Kuril varieties
How do the Kuril varieties relate genetically to Hokkaido and Sakhalin according to lexicostatistics?
The Kuril language spoken in the Northern Kuril Islands (such as Shumshu and Paramushir) is regarded as a dialect of Ainu, termed (North) Kuril Ainu. (Nakagawa 2024: 84) Krasheninnikov recorded the Northern Kuril word for 'father' as Mitschi (modern mici), a word whose distribution is otherwise limited to eastern Hokkaido and the Pacific coast. (Nakagawa 2024: 84) The Kuril dialect of Ainu had elderly speakers who remembered it up until around 1912, but subsequently became completely extinct. (reported in Nakagawa 2024: 86) Toponyms recorded in the southern Kuril and Kamchatka area include forms such as pit 'river', corresponding to Hokkaido Ainu pet. (reported in Nakagawa 2024: 86) The self-designation Uipit yeeke recorded for the inhabitants of Cape Lopatka on the Kamchatka Peninsula is difficult to interpret as Ainu. (Nakagawa 2024: 86) Southern Kuril dialects did not differ substantially from Hokkaido dialects and are typically regarded as Hokkaido dialects. (reported in Nakagawa & Fukazawa 2022: 8.6) The Northern Kuril dialects are distinct from the Hokkaido dialects. (Nakagawa & Fukazawa 2022: 8.6)
Northern contact and the Hokkaido residue
Which languages were in contact with Sakhalin Ainu and how widespread was multilingualism?
The endonym Enchiw is synchronically attested only in Sakhalin Ainu and has been compared with Japanese Emishi, Ebisu, and Ezo. (Janhunen 2022: 2.3)
