2. A Typological Profile of Hokkaido Ainu
What is the typological profile of Hokkaido Ainu?
The self-designation ainu means 'person' (Bugaeva 2012). The language has three primary dialect divisions: Hokkaido, Sakhalin, and the Kurile Islands (Bugaeva 2012). Ainu has a relatively small phonemic inventory compared to the world's languages, and its syllable structure is not complex (Nakagawa 2024: 25). In complex sentences, Ainu exhibits predominantly dependent-marking patterns, as in relative clauses and most subordinate clauses (Bugaeva 2022: 1.6). The syntactic process of head movement is not essential in describing the grammatical structure of Ainu (Satō 2025).

The genetic isolate and its typological placement
How is Hokkaido Ainu classified genetically and typologically?
Ainu is a genetic isolate that differs strikingly from the languages of Northeast Asia, including the Altaic languages, Korean, Japanese, Nivkh, Yukaghir, and Chukchi-Kamchatkan (Bugaeva 2022: 1.1), and is grammatically entirely dissimilar to Japanese, in contrast to many neighboring languages that share grammatical similarities with it (Nakagawa 2024: 15). Typologically, Ainu is consistently described as agglutinating, polysynthetic, and head-marking (Bugaeva 2006: 185, Bugaeva 2012, Bugaeva 2014, Bugaeva 2022: 1.1). It is also an incorporating language with SOV constituent order (Bugaeva 2012, Bugaeva 2014, Nam 2021). Ainu is characterized by the predominance of postpositions, person marking on verbs and nouns, and a rich valency-changing system, with polysynthesis manifested by productive noun incorporation (Nam 2021). Unlike the Tungusic languages of Sakhalin, Hokkaido Ainu lacks subordinating non-finite verbal forms (Bugaeva 2016).

Head-marking, indexing, and the absence of case
Does Hokkaido Ainu use head-marking or dependent-marking for syntactic relations?
Ainu belongs typologically to the predominantly head-marking language type, a characterisation asserted by multiple scholars (Bugaeva 2016, Satō 2025), and is head-marking both at the clause level and at the phrase level (Bugaeva 2022: 1.1). Most key grammatical features in Ainu are either directly or indirectly related to head-marking (Bugaeva 2022: 1.1). Ainu is predominantly head-marking at the clause and noun phrase levels and partially at the sentence level, distinguishing it from the predominantly dependent-marking languages of Northeast Asia (Bugaeva 2022: 1.7). The possible arguments of a verb are marked with personal affixes on the verb, which obligatorily marks arguments on the predicate as the clausal head (Satō 2025). Ainu is predominantly head-marking and prefixing (Bugaeva 2012). Nouns and personal pronouns lack case inflection (Bugaeva 2008), and Ainu has no verbal inflections (Shibatani 1990: 6). Some adverbial clauses are head-marked, in that a conjunctive element can follow sentence-final intonation and be uttered with the following sentence or verb phrase (reported in Bugaeva 2022: 1.6). In evidential noun complement clauses, Bugaeva proposes that the complementizer markers belong to the main clause while leaving the subordinate clause intact, exhibiting a head-marking pattern (proposed in Bugaeva 2022: 1.6). In complex sentences, however, Ainu exhibits predominantly dependent-marking patterns in relative clauses and most subordinate clauses (Bugaeva 2022: 1.6).

Possession indexed on the head noun
How does Hokkaido Ainu mark possession in the noun phrase?
Polysynthesis and noun incorporation
Is Hokkaido Ainu a polysynthetic language, and does it allow noun incorporation?
Ainu is consistently described as a polysynthetic and incorporating language (Bugaeva 2016, Bugaeva 2022: 1.1). Ainu exhibits polysynthesis, wherein directional/applicative, reciprocal, and reflexive voice markers, as well as adverbs and nouns when semantically required, attach to the verb stem (Kindaichi & Chiri 1936). Polysynthetic characteristics are more prominent in Classical Ainu than in the colloquial dialects (Shibatani 1990: 4, 16; reported in Majewicz 2022: 4.5). Because Ainu is polysynthetic, many Ainu loanwords in Eastern Old Japanese are compounds or complex morphological derivations (Vovin 2022: 6.2).

SOV order and the head-final clause
What is the basic constituent order of Hokkaido Ainu clauses?
Ainu is an SOV language (Shibatani 1990: 22). The prevalent occurrence of prefixes in Ainu is an exceptional characteristic for an otherwise head-final SOV language (Shibatani 1990: 16).

Typologically unusual features in the regional context
What typologically unusual features does Hokkaido Ainu have in its regional context?
Ainu extensively uses prefixation, a typological feature uncommon in the languages of the North Pacific Rim (Bugaeva 2012: 462–463), and employs more prefixation than suffixation (Bugaeva 2016).
