Chapter 144Interrogative Strategies, Question Particles, and Evidential Questions

144.1 Overview

Hokkaido Ainu marks clause-level interrogation through four intersecting mechanisms: rising intonation alone, sentence-final particles, a constituent-scoping focus-question particle, and the sentence-type alternation on the formal-noun evidential tail. Wh-pro-forms remain in their canonical argument or adjunct position throughout — there is no wh-movement and no obligatory cleft for question formation Nakagawa (2024: 409–412); Satō (2008: 136–138). The wh-pro-form inventory — hemanta ‘what’, hunna ‘who’, hunak ‘where’, hempara ‘when’, and their dialectal alternants — is documented in Chapter 51 (Interrogative, Indefinite, and Negative-Polarity Pro-forms); this chapter describes the clause-level framing strategies, the interrogative particles, and the conventions for answering questions.

Two particles carry most of the segmental interrogative work. he scopes over the constituent at issue rather than the whole clause, placing it closer to a 副助詞 than to a canonical sentence-final particle in its distribution ‹contested› Fukuda (1961: §8, §31); Nakagawa (2024: 323–324). ya (post-consonant allomorph a) is a true sentence-final particle that also nominalizes a clause as 'whether …' in embedded questions Nakagawa (2024: 332–333). The deepest structural mechanism, however, is the alternation among the copula ne, the existential an, and the ∅-tail on the formal nouns ruwe ‘track-POSS’, hawe ‘voice-POSS’, siri ‘appearance-POSS’, and humi ‘sound-POSS’: the same nominal that closes a declarative as ruwe ne becomes a polar question as bare ruwe and a content question as ruwe an. The inferential evidential and its frame alternations are treated fully in Chapter 121 (ruwe ne — the Inferential / Visual-Trace Evidential); the full sentence-final particle inventory is in Chapter 143 (The Sentence-Final Particle System and Illocutionary Force). A pedagogical overview of question formation is in Ijäs (2023).

144.2 Polar questions: five strategies

Nakagawa identifies five overlapping strategies for forming polar (yes/no) questions, any of which may combine with another Nakagawa (2024: 409):

Strategy (a) — rising intonation without any segmental reflex — is the unmarked polar-question device Nakagawa (2024: 409); Satō (2008: 136). It leaves no trace that would survive in written documentation; Fukuda's treatment of sentence melody carefully separates prosodic questioning from the particle system Fukuda (1961: §31). Strategy (b) uses the bare formal noun, the ∅-tail alternant of the evidential predicate. The example below shows it with hawe ‘voice-POSS’:

The same ∅-tail applies to ruwe, here inside a conditional permission request:

Strategy (e) reinforces the polar question by inserting he between the bare formal noun and the existential an, producing the frame ruwe he an:

144.3 The sentence-type alternation on formal-noun tails

When a clause is nominalized by one of the four formal nouns, the predicate following the nominal determines sentence type. Satō documents the three-way pattern for all four formal nouns Satō (2008: 136–137), confirmed in detail by Nakagawa Nakagawa (2024: 394–396):

Satō proposes a structural motivation: the copula ne predicates the nature of the subject, so the declarative asserts what something is; the existential an asserts that a situation exists while its nature remains open to the wh-word in a content question; and the bare formal noun without either predicate treats even the existence of the described state as the open question — the polar reading Satō (2008: 137) ‹speculative›. The account is Satō's own working hypothesis, not a derivation shared across the sources consulted.

Nakagawa gives the content question an additional expansion: NMLZ an hi an — existential, then the formal noun hi ‘time, place, fact (formal noun)’, then existential again — emphasizes the facthood of the unknown element Nakagawa (2024: 410). The alternation also disambiguates near-identical wh-clauses: hemanta an? = 'what (is there)?' versus hemanta ne? = 'what is it?' / 'why?' — the choice of an vs ne after a wh-word marks open-existence question vs identification Nakagawa (2024: 412). The evidential-tail system and the semantics of ne vs an are set out in the frames section and in Chapter 120 (The Nominalization-plus-Copula Evidential Schema).

144.4 The he particle: scope and category

Fukuda classifies he as a 副助詞 on distributional grounds: it attaches after any constituent — noun, postpositional phrase, verb, adjective, or conditional clause — and marks that constituent as the locus of uncertainty, so it may stand inside the clause rather than at the sentence boundary Fukuda (1961: §8); Nakagawa (2024: 323–324). When it happens to fall at the clause end Fukuda notes a category straddle toward the sentence-final class Fukuda (1961: §31) ‹contested›; Nakagawa and Satō describe it functionally rather than categorially, emphasizing its constituent-scoping behaviour Nakagawa (2024: 323–324); Satō (2008: 63).

The following example places he after a conditional clause, making the conditional — not the final adjective — the questioned element:

When placed after a postpositional phrase, he turns that phrase into a focused confirmation request, even as a fragment without a full predicate:

In content questions, he marks the wh-adjunct cluster as the focal unknown and can combine with the wh-word in the adjunct slot:

Satō notes that the most characteristic use of he is the disjunctive frame X he … Y he …, which poses an either/or choice between two alternatives Satō (2008: 63); this overlaps with the alternative-question strategy described below.

Three dialect-restricted particles cover overlapping territory. hetap (henta in some sources) marks formal or dubitative polar questions in the area west of Shizunai. enta (Shizunai-area) marks the specific element in doubt, paralleling he in narrow scoping. omoun (Shizunai-area) signals a conjectural question Nakagawa (2024: 324, 326). All three coexist with the pan-dialectal he, which carries no dialect restriction.

144.5 The ya/a question particle

ya is a sentence-final particle that marks the clause as a question — polar or content — without scoping any particular constituent Nakagawa (2024: 332–333); Fukuda (1961: §29). Its post-consonant allomorph a is not merely phonological reduction: Nakagawa treats it as a genuine second particle form Nakagawa (2024: 333).

Satō observes that ya alone on a bare verb can sound abrupt or overly direct; it frequently accompanies a formal-noun frame or a softening particle Satō (2008: 74). The particle marks polar questions:

ya also closes content questions where the wh-word and a nominalized predicate already supply the interrogative content. The Tokachi allomorph a appears in a recognizable dialectal content-question frame:

Beyond its SFP use, ya nominalizes a clause as 'whether …' when embedded under a verb of knowing or investigating; in that function it is a complementizer, not a sentence-final particle, and the embedded polar question is the object complement of the matrix verb Nakagawa (2024: 333); Satō (2008: 74). The complementizer function is addressed in the section on embedded questions below.

A community analysis proposes that the disjunctive conjunction neya ‘or’ is historically ne + ya ('be' + Q-particle → 'or'), the Q-particle supplying the alternative reading ‹contested› aynu-corpora Discord (2023–2026) (aomidori_cs_, 2023-12-12). This etymology is consistent with the pattern but is not independently documented in the sources consulted.

144.6 Content questions: wh in situ

Content questions retain the wh-pro-form in its canonical argument or adjunct position. Nothing moves. When a formal-noun tail is present, the copula is replaced by the existential an, producing ruwe an / hawe an etc., or the expanded NMLZ an hi an frame Nakagawa (2024: 410); Satō (2008: 136–137). Without a formal-noun tail, any of the polar-question devices — rising intonation, ya, or he on the focal wh-element — also marks a content question.

The wh-pro-form inventory has a two-way split between question-word shapes (hunna ‘who’, hemanta ‘what’, hunak ‘where’, makanak ‘how’) and indefinite shapes (nen ‘someone’, nep ‘something’, ney ‘somewhere’, neun ‘somehow’). The indefinite shapes combine with the additive particle ka ‘also, even’ to produce 'someone/something/somewhere' in positive contexts and 'no one/nothing/nowhere' under negation Satō (2008: 137); Nakagawa (2024: 322–323). The full paradigm and its dialectal variants are in Chapter 51 (Interrogative, Indefinite, and Negative-Polarity Pro-forms) and Chapter 67 (The Indefinite/Fourth Person: Forms, Reference, and Agent-Defocusing).

The constraint on the formal-noun tail means that the ne / an choice disambiguates otherwise similar clauses. The declarative hemanta ne? = 'what is it?' / 'why?' (copula, identifying) contrasts with the existential content question hemanta an? = 'what is there?', and the obligatory existential tail in the presence of a wh-word (*hemanta ne kusu ene siran hi ne is ungrammatical as a question) follows from the sentence-type alternation described in the preceding section Satō (2008: 136–137); Nakagawa (2024: 412).

144.7 Alternative and disjunctive questions

Disjunctive alternatives use the particle hene ‘or; for instance’ repeated after each alternative member Nakagawa (2024: 323–324); Fukuda (1961: §6). Tokachi and some eastern varieties use ene in this function Nakagawa (2024: 323). For an alternative question, the same hene disjunction frame receives a polar-question marking — rising intonation, ya, or he after each alternative:

The X he … Y he … frame identified by Satō as he's most characteristic use Satō (2008: 63) extends the same logic to alternative verbal predicates: placing he after each alternative focuses the question on the choice between them. hene also heads listing alternatives in declarations ('for instance, tomorrow or the day after'); intonation and context distinguish the question reading from the declarative listing.

144.8 Embedded questions

Embedded polar questions use ya as a nominalizing complementizer: the clause ending in ya is treated as a nominal 'whether [proposition]' and functions as the complement of a verb of knowing or asking Nakagawa (2024: 333); Satō (2008: 74). This complementizer function is formally parallel to the nominalizers p ‘thing, fact (nominalizer)’ and hi ‘time, place, fact (formal noun)’ treated in Chapter 101 (The Nominalizers -p/-pe and -i/-hi (Participant, Event, Place, Fact)).

Embedded content questions use a different frame. The complementizers kunak, yak, and kuni introduce indirect-speech and indirect-question complements under transitive reporting verbs such as ramu ‘think’ or ye ‘say’ Bugaeva (2008: 35–37); Nakagawa (2024: 470–472). These contrast with the quotative particle sekor, which introduces direct and semi-direct speech under intransitive verbs; the transitivity split (sekor ⇒ intransitive reporter, kuni ⇒ transitive reporter) is confirmed by community observation aynu-corpora Discord (2023–2026) (nukopoli, 2024-11-09) ‹speculative›. The direct/semi-direct/indirect speech continuum, person-switching in logophoric speech, and the sekor / kuni contrast are treated in Chapter 131 (Clause Linkage in Ainu: Typology and Inventory).

144.9 Answer and response strategies

Hokkaido Ainu has no grammaticalized 'yes' and 'no' particles used crosslinguistically to confirm or deny a proposition directly. The standard response to a polar or content question repeats the relevant verb — in its positive form to confirm, or with negation somo to deny — and may add a reason clause Nakagawa (2024: 396). Community documentation from across several dialects corroborates this: in most dialects outside Saru, bare affirmative or negative interjections are not used to answer a question, and the verb-repetition strategy is employed exclusively. Saru aligns more closely with Japanese-style polarity responses. Forms such as e, ho, and m are responses to being addressed or called, not affirmation/denial particles aynu-corpora Discord (2023–2026) (nukopoli, 2024-12-04) ‹speculative›.

One attested affirmative-response frame retains the formal noun and adds the sentence-final particle un:

The particle wa (soft assertive) also frequently closes replies, softening the declarative force of a repeated or corrective statement Nakagawa (2024: 334); Fukuda (1961: §21). Neither the Q-particles nor the response particles are gender-restricted: HA has no sentence-final particle specific to men or women Satō (2008: 72). The male-register skew noted for ruwe ne in oral narrative is a property of the evidential class, not of the SFP class, and the two systems should not be conflated ‹corpus-suggested›; see Chapter 145 (Gendered Speech and Pragmatic Registers) for oral-register distinctions and the semantics of ruwe ne for the gendered-register side of the evidential.
