Chapter 167Synopsis of Lexical-Semantic Fields
A field-by-field synopsis of the Ainu lexicon — its semantic organization, the classified-dictionary tradition, and culturally salient vocabulary domains.
167.1 Overview
The native core of the Hokkaido Ainu lexicon is organized around a small number of semantic fields whose internal structure feeds directly into the grammar. Kinship terms and body-part nouns constitute the obligatorily-possessed (bound) noun class. Motion verbs supply the primary paradigm of singular/plural stem suppletion. Colour terms and property-denoting natural-world vocabulary are encoded as stative verbs, with no separate adjectival category. Demonstratives, locative nouns, and postpositions combine into a layered spatial-deictic system anchored to river orientation. The table below maps each field to its grammatically active sub-structure and to the chapters that give the full account. For vocabulary lookup, the Itak dictionary carries the attested lexicon; this chapter is a finding aid, not a word list. Bugaeva (2022: §5.1.1)

| spatial demonstratives and locative nouns | three-term deictic contrast; obligatorily-possessed locative nouns; postpositional layering | Chapter 50 (Demonstratives, Anaphora, and Definiteness), Chapter 52 (Relational and Spatial (Locative) Nouns and Their Possessed Forms) |
The contact stratum — Japanese loans clustering in the domains of domestic animals, trade goods, administration, and modern institutions — is treated in the contact-lexicon chapter. Loanword phonological adaptation (voicing neutralization, cluster break-up, epenthesis) is treated in Chapter 21 (Syllable Structure, Phonotactics, and Word-Edge Constraints). The vigesimal numeral system and its classifier constructions belong to Chapter 54 (The Vigesimal Numeral System) and Chapter 55 (Numeral Classifiers, Ordinals, and Quantifier Syntax); the genetic position and typological profile implied by the native core lexicon are discussed in Chapter 5 (The Genetic Position of Ainu: Isolate Status and Macro-Comparison Controversies).
167.2 Kinship terms
The kinship vocabulary encodes a four-axis grid: sex and relative age of the referent in sibling terms; sex of the referent in lineal terms. All kinship nouns are obligatorily possessed: they cannot appear without a possessor prefix, and their possessed (affiliative) form is built by the same suffix alternation found on body parts and relational nouns (see Chapter 45 (Morphophonology of the Affiliative Suffix and Echo/Copy Vowels)) Bugaeva (2022: Ch.1 §5.1); Nakagawa (2024: §22.2). The following table gives the principal Saru-dialect terms with their standard meanings; the kinship system and its possessive morphology are treated fully in Chapter 48 (Kinship and Honorific Possession).
| term | meaning (Saru baseline) | register |
|---|---|---|
| hapo ‘mother’ | mother | adult colloquial |
| totto ‘mummy (infant speech)’ | mother (infant-directed) | infant speech |
| michi ‘father’ / aca ‘father (variant)’ | father | adult |
| yupo ‘elder brother’ | elder brother | adult |
| aki ‘younger brother’ | younger brother | adult |
| sapo ‘elder sister’ | elder sister | adult |
| matak ‘younger sister’ | younger sister | adult |
| huci ‘grandmother; fire goddess’ | grandmother; by extension, the fire goddess | adult |
| ekasi ‘grandfather; elder man’ | grandfather; elder man (respectful) | adult |
| mat ‘wife, woman’ | wife; woman | adult |
| hoku ‘husband’ | husband | adult |
| po ‘child (one's own)’ | child (one's own) | adult |
The following constructed example shows the obligatory possessor prefix and the affiliative suffix on a kinship noun:
‘my elder brother’
constructed example
The 1SG possessor prefix ku= and the affiliative suffix -ihi co-occur; the possessed form yup-ihi suppresses the final vowel o of the citation form yupo. Third-person possessor is zero-marked: yup-ihi alone = 'his/her elder brother'.
A register split divides adult and infant-directed forms: totto ‘mummy (infant speech)’ and popo ‘big brother (infant speech)’ are the infant-directed counterparts of hapo and yupo, attested in Nakagawa's infant-speech table for the Horobetsu dialect Nakagawa (2024: 523). Literary and formal registers additionally have ona ‘father (literary)’ and unu ‘mother (literary)’ as honorific equivalents of the colloquial forms, though their distribution and exact mapping vary by dialect (nukopoli, aynu-corpora Discord 2026-06-15; aynu-corpora Discord (2023–2026)).
Dialect variation within the kinship field is considerable. hapo denotes the mother in most Hokkaido dialects but the father in Chitose and Horobetsu (thegodofneet, aynu-corpora Discord 2026-06-08, asserted; aynu-corpora Discord (2023–2026); corroborated by Chiri (1953)) ‹corpus-suggested›, and the Kuril reflex carries a sibling reading. Such semantic drift is characteristic of kin terms cross-linguistically. The possessive morphology of kinship nouns, including their suppletive affiliative forms and the honorific use of the fourth/indefinite person in possession, is treated in Chapter 48 (Kinship and Honorific Possession); the alienability classification they belong to is in Chapter 43 (The Alienable/Inalienable Split and Possessive Classification).
167.3 Body-part terms
Body-part nouns are the second major obligatorily-possessed class. Like kinship terms, they require a possessor and appear in the possessed (affiliative) form; the suffix alternates among -e, -i, and -ihi depending on the noun's final consonant and vowel quality (see Chapter 45 (Morphophonology of the Affiliative Suffix and Echo/Copy Vowels)) Bugaeva (2022: Ch.1 §5.1). Core Saru terms include sik ‘eye’, tek ‘hand’, kema ‘leg’, nanu ‘face’, sapa ‘head’, kewtum ‘heart, chest, mind’, ramu ‘heart, spirit, mind’, honi ‘belly’, haw ‘voice’, and etor ‘snot’ Tamura (1996: s.v.).
Body-part nouns are the primary context for S-type noun incorporation with valency-retaining effect: when a body-part noun is incorporated as the S argument of an intransitive verb, the possessor of that body part surfaces as an added participant rather than being absorbed, so the construction gains a slot rather than losing one Bugaeva (2022: Ch.1 §4.6); Satō (2016). This contrasts with the valency-canceling O-incorporation typical of common object nouns (see Chapter 88 (Object (Patient) Noun Incorporation)). External possession — where the possessor of a body-part object is indexed on the verb rather than carried adnominally — is treated in Chapter 47 (External Possession and Possessor Raising). The full account of body-part S-incorporation is in Chapter 89 (Subject Incorporation and Possessor-Stranding).
The near-synonymous pair kewtum ‘heart, chest, mind’ and ramu ‘heart, spirit, mind’ is pervasive in compounds and in oral literature. Their distribution is partly dialectal and partly a distinction between the physical chest/heart and a more diffuse psychological or spiritual sense; both participate in compounding productively (e.g. kewtum-pirka 'be good-hearted', ramu-pok 'think little of'). A community-proposed internal morphological analysis of esikop ‘parent’ as e-sik-o-p 'thing from which eyes come' (nukopoli, aynu-corpora Discord 2023-12-11, proposed; aynu-corpora Discord (2023–2026)) illustrates the general productivity of body-part roots in derivation, though the specific etymology has not been verified in the published literature ‹speculative›.
167.4 The natural world: geography, flora, fauna, and weather
167.4.1 Geographic vocabulary
Geographic vocabulary is among the richest and highest-frequency sub-fields of the native lexicon. The core set includes kotan ‘village, settlement’ (4,210 corpus tokens, rank 56), pet ‘river (the area's representative river)’ (1,353 tokens), nay ‘stream, tributary’ (559 tokens), to ‘lake, pond’, nupuri ‘mountain’, atuy ‘sea’, sir ‘land, surface, appearance’, and mosir ‘world, island, land’ Tamura (1996: s.v.); Nakagawa (1995: s.v.).
The pet/nay distinction encodes a cultural-geographic rather than a purely scalar opposition. pet designates the main, named river of an area — even a small flow, if it is the representative waterway of that locality — while nay designates a branch stream or tributary, which may physically exceed a local pet in volume. The community corroborates this distinction: nay = mountain stream/tributary, to = pond (nukopoli, aynu-corpora Discord 2023-12-11, asserted; aynu-corpora Discord (2023–2026); consistent with Tamura (1996: s.v. pet, nay)) ‹corpus-confirmed›. Both roots are morphologically unanalyzable and drive the major toponym substrate of Hokkaido (Japanese -betsu < pet, -nai < nay), discussed in Chapter 5 (The Genetic Position of Ainu: Isolate Status and Macro-Comparison Controversies).
sir ‘land, surface, appearance’ is notably polysemous: it covers the physical land surface, the external appearance or state of affairs, and the condition of the weather (as in compounds sir-pirka 'the weather is good', sir-kunne 'it grew dark'). The same root forms the base of the situational evidential siri (see the situational evidential). The community notes that the derived form sirka ‘surface, surroundings’ inherits the full polysemy of the base (nukopoli, aynu-corpora Discord 2023-12-15, asserted; aynu-corpora Discord (2023–2026)) ‹corpus-confirmed›.
167.4.2 Flora and the kina/mun distinction
The folk-taxonomy of plants is organized around ni ‘tree, wood’, kina ‘edible or useful plant’, and mun ‘inedible plant, weed’. The kina/mun opposition lexicalizes a cultural distinction — useful/edible versus useless/noxious — that carries no grammatical reflex but is visible throughout plant names and in compounds with kina Vovin (2022: Ch.6 n.5). The assignment of a plant to one category or the other can differ across dialects, depending on local usage and ecology.
167.4.3 Fauna
Core fauna terms include cep ‘fish’, kamuy ‘bear; deity, supernatural being’, cikap ‘bird’, and yuk ‘deer’. kamuy occupies a grammatically and culturally central position: in its unmarked referential use it denotes the brown bear as the foremost hunting deity, but it extends to any powerful supernatural being, to forces that exceed ordinary understanding, and to a range of compounded divine titles Bugaeva (2022: Ch.1 §1). Its very high corpus frequency reflects its pervasive presence in oral literature and ritual language. Domestic animals introduced through contact are loanwords: umma ‘horse’ (< Japanese うま), meko ‘cat’ (< Japanese ねこ), and peko ‘cow’ Chiri (1953: §293, §266).
A community-proposed internal analysis reads cep ‘fish’ as ci=e-p 'the thing (p) that one (ci=) eats (e)' — an argument-structure nominalization in which the middle-voice prefix fills both subject and object slots (nukopoli, aynu-corpora Discord 2023-12-06, proposed; aynu-corpora Discord (2023–2026)) ‹speculative›. The analysis is internally consistent with the productive nominalizer -p, but the synchronic morphological boundary is opaque in the modern form and the etymology has not been verified in the published descriptive literature.
167.4.4 Weather and natural-phenomenon vocabulary
Weather vocabulary includes apto ‘rain’, rera ‘wind’, and upas ‘snow’. The compound sir-pirka ‘the weather is good (lit. the land/appearance is good)’ is the standard illustrative example of S-type noun incorporation with a natural-phenomenon subject: the incorporated element sir fills the S slot of the intransitive stative pirka ‘be good, be beautiful’, producing a valency-canceling effect in which the incorporated noun — not an independent NP — bears the subject role Bugaeva (2022: Ch.1 §4.6).
A community-proposed reconstruction treats the initial vowel of upas ‘snow’ as secondary, with *o- as the original form, against the folk-etymology parsing it as u-pas (antitwilight, aynu-corpora Discord 2024-12-23, proposed; aynu-corpora Discord (2023–2026)) ‹speculative›.
167.5 Motion and directional verbs
Motion verbs are the primary locus of SG/PL stem suppletion in Hokkaido Ainu. The principal suppletive pairs are arpa ‘go (SG)’/paye ‘go (PL)’, ek ‘come (SG)’/arki ‘come (PL)’, and an ‘be, exist (SG)’/oka ‘be, exist (PL)’ Nakagawa (2022); Bugaeva (2022: Ch.1 §4.2). Number agreement targets the S or A argument of the verb; the outer plural suffix -pa and the full account of suppletive and suffixal plural strategies are in Chapter 58 (Verbal Number: Suppletive Stems and the Pluractional -pa).
The path-encoding set includes san ‘go seaward or downstream’ (movement toward the sea or downslope), yan ‘go inland, come up onto land’ (movement away from the sea or upslope), oman ‘go’, hosipi ‘return’, ahun ‘enter’, and soyne ‘go out’. The san/yan pair encodes a coast-relative or river-relative directionality: san moves toward the water or its outlet and yan moves away from it. These verbs combine with applicative prefixes and directional roots to build complex path constructions (see Chapter 53 (Postpositions, Local Case, Motion Events, Comitative, and Instrumental) and Chapter 78 (The Applicative System: Overview and the Preverb-vs-Applicative Debate)) Nakagawa (2024: §6).
The directional vocabulary extends to adverbial spatial terms: penke ‘upstream side, upper portion’ and panke ‘downstream side, lower portion’ locate entities relative to water flow rather than to the speaker's body axis Tamura (1996: s.v. penke, panke). This river-anchored orientation appears as a component in Hokkaido place names and governs orientation in oral-literature narrative.
A morphological alternation recurs in several motion verb bases: beside the -n-final form, a parallel -p-final form exists (san/sap, yan/yap, ahun/ahup). The pair is widely noted in Ainu linguistics; the origin of the alternation — whether the -p descends from the pluractional suffix -pa, from a distinct derivational suffix, or from another source — is debated (nukopoli, aynu-corpora Discord 2026-05-18, proposed; aynu-corpora Discord (2023–2026)) ‹contested›.
167.6 Colour terms
The basic colour vocabulary of Hokkaido Ainu comprises four stative verbs. Ainu has no separate adjective word class (see Chapter 37 (The 'No Adjective Class' Thesis: Property Concepts as Stative Verbs)): colour terms are intransitive stative verbs predicated directly without a copula, and they modify nouns attributively in their concept form (see Chapter 44 (Concept Form vs. Affiliative (Possessed) Form)) Nakagawa (2024: §3). The four basic terms and their corpus frequencies are:
| stative verb | primary colour range | extended use | corpus tokens |
|---|---|---|---|
| retar ‘be white’ | white | dawn brightness; purity | 262 |
| kunne ‘be black, be dark’ | black, dark | nightfall (kunne sir 'it grew dark') | — |
| hure ‘be red’ | red | blood, fire, sunset | 184 |
| siwnin ‘be blue-green (grue)’ / sinnin | blue-green (grue) | reported also for purple and yellow (see below) | — |
kunne serves as the predicate of nightfall as well as of the colour black; retar describes the light of dawn as well as the colour white Tamura (1996: s.v. kunne, retar). The terms thus participate in the temporal-lighting vocabulary beyond their core chromatic meanings. A community-proposed internal etymology reads kunne as kur-ne 'to be like a shadow/person' (kur ‘shadow, person’ + copula ne ‘be (copula)’) (nukopoli, aynu-corpora Discord 2024-06-18, asserted; aynu-corpora Discord (2023–2026)). The segmentation is internally consistent — the copula ne productively derives stative verbs in Ainu — but has not been confirmed in the published philological literature ‹speculative›.
siwnin is typologically notable: it covers the blue-green continuum without a primary split, fitting the classic grue pattern of Shibatani (1990: §1). Dictionary records indicate that the term's range may extend beyond the blue-green merger to include purple and possibly yellow in some usage (toracatman, aynu-corpora Discord 2024-05-30, asserted; aynu-corpora Discord (2023–2026)) ‹corpus-suggested›, though no systematic colour-category survey of Ainu has been conducted. A Tokachi example using siwnin in an evidential construction appears in Chapter 121 (ruwe ne — the Inferential / Visual-Trace Evidential) (taan imo siwnin ru an 'this potato is green', Takahashi (2013: 131–133)), where the individual-level property takes the trace-nominalizer evidential rather than the visual.
A community proto-Ainu reconstruction for retar ‘be white’ proposes an earlier cluster-initial form *tretar/*dretar on the basis of a Taraika Sakhalin reflex tetar (antitwilight, aynu-corpora Discord 2024-11-24, proposed; aynu-corpora Discord (2023–2026)), consistent with the comparative program of (Vovin 1993) and (Alonso de la Fuente 2022) ‹speculative›. This is noted as a lead for the historical phonology; verification requires the primary comparative data.
167.7 Spatial deixis and locative nouns
The spatial deictic system has three interacting layers: a demonstrative series, a set of obligatorily-possessed locative nouns, and a small set of postpositions. Their full accounts are distributed across Chapter 50 (Demonstratives, Anaphora, and Definiteness), Chapter 52 (Relational and Spatial (Locative) Nouns and Their Possessed Forms), and Chapter 53 (Postpositions, Local Case, Motion Events, Comitative, and Instrumental). The synoptic inventory is:
| layer | form(s) | spatial or discourse value |
|---|---|---|
| demonstratives | tan ‘this (proximal)’ / taan | proximal (near speaker) |
| toan ‘that (distal)’ / toon | distal (away from speaker) | |
| nean ‘that (anaphoric)’ / ne | anaphoric (discourse-given referent) | |
| locative nouns (obligatorily possessed) | or ‘place, location’ | general locative; possessed form oro |
| ka ‘top, surface’ | superessive; possessed form kasi | |
| sam ‘side, vicinity’ | proximate lateral | |
| tum ‘middle, interior’ | interior/medial | |
| pokna ‘below, under’ | subessive | |
| rikun ‘above’ | superessive-high | |
| postpositions | ta | static locative (LOC) |
| un | goal/allative | |
| wa | source/ablative |
The demonstrative series is three-way: proximal tan/taan (near speaker), distal toan/toon (away from speaker), and anaphoric nean/ne (discourse-established referent) Nakagawa (2024: §10); Takahashi (2011). Within the proximal slot, the longer form taan has been proposed to carry greater information content or emphasis relative to tan, and a sound-symbolic account has been proposed in which narrow front vowels index proximity and broader back vowels index distance (nukopoli, aynu-corpora Discord 2025-12-27, proposed; aynu-corpora Discord (2023–2026)) ‹contested›. The full discourse-anaphoric and definiteness functions of the series are treated in Chapter 50 (Demonstratives, Anaphora, and Definiteness).
Locative nouns (or, ka, sam, tum, etc.) are obligatorily possessed: a referential head NP must serve as their possessor. The postposition ta (LOC) then follows the possessed locative noun to form a spatial phrase: pet or ta 'at the river', cise ka ta 'on top of the house'. Among these, or shows a grammaticalization drift in the corpus, encroaching on the functions of a general locative case marker Satō (2021); Nakagawa (2024: §11).
‘I am by the river.’
constructed example
The locative noun or 'place' takes the river NP pet as its possessor; the postposition ta marks static location. The possessor relation is adnominal: pet is 'the river's place'. First-person S is marked by the intransitive suffix =an on the existential verb.
The directional system is river-anchored at the adverbial level: penke ‘upstream side’ and panke ‘downstream side’ locate entities relative to water flow rather than to the speaker's body axis Tamura (1996: s.v. penke, panke). This axis governs orientation in narrative and appears as a component in Hokkaido place names. Its integration with the postpositional and motion-event system — including its interaction with san ‘go seaward’ and yan ‘go inland’ — is treated in Chapter 53 (Postpositions, Local Case, Motion Events, Comitative, and Instrumental).
