Chapter 142Pragmatic Word-Order Permutation, Dislocation, and Argument Ellipsis

142.1 Overview

Hokkaido Ainu has one rigid clause-level constraint: the verb phrase — together with any evidential — comes last, and all other elements precede it Nakagawa (2024: 363). Within the preverbal domain, however, the relative sequence of nominal and adverbial phrases is not grammatically fixed. Because grammatical roles are indexed on the verb by obligatory person affixes (see Chapter 62 (Architecture of the Personal-Affix System: The Four Persons and the S/A/O Paradigms)), and overt NPs stand in an appositional relation to those affixes rather than filling assigned slots (see Chapter 93 (Argument Realization: Affix Indexing and Free NP Order)), the preverbal domain is available for information structure to impose its own ordering — independently of the S/A/O distinctions encoded morphologically.

Several distinct operations occupy this space. Topical elements tend to appear at the left edge of the preverbal sequence, most visibly when marked by the topic particle anakne ‘as for (topic marker)’. A contrastively stressed indirect object may be fronted and receive an allative postposition it would otherwise lack. An adverbial complex can appear in any order relative to the NPs around it. And a third-person NP can be placed after the verb and re-predicated by the light verb ki ‘do’ — a right-dislocation strategy that Bugaeva connects to processing and to the disambiguating function that verb-initial order performs in other head-marking languages Bugaeva (2022: ch.1 §4.3).

This chapter describes those positional operations and the discourse conditions that license each. The topic-particle system — anak(ne), the additive-focus particle ka ‘also; even’, and the exclusive-focus adverb patek ‘only, just’ — is treated in full in Chapter 140 (Topic and Focus Marking: anak(ne), patek, and ka); cleft and nominalization-based focus constructions belong to Chapter 141 (Cleft, Pseudocleft, and Nominalization-Based Focus). Argument ellipsis proper — the conditions under which a recoverable NP is simply omitted — is covered in Chapter 93 (Argument Realization: Affix Indexing and Free NP Order) and Chapter 139 (Reference Tracking and Argument Continuity); what this chapter addresses is how ellipsis conditions the use (and non-use) of fronting and dislocation.

142.2 Topic-initial order and left-fronting

The most consistently stated pragmatic generalization in the literature on Ainu word order is that topical NPs tend to come first Bugaeva (2012: 472). Nakagawa frames the same observation structurally: rather than a subject-before-object preference, the preverbal sequence is organized by information status, so that the element made topic by anak(ne) or ka tends to occupy the initial position Nakagawa (2024: 364). His Chitose paradigm — the same ditransitive event narrated with the three arguments of epakasnu ‘teach’ in three different orders — makes the point directly: the order shifts with the topic-marking, and order alone cannot determine which argument is agent or recipient (Nakagawa 2024: 363, exx.700–702; see Chapter 92 (Basic Constituent Order and Head-Final Syntax)).

Three corpus examples from different narrators and registers show the range of what can be fronted:

All three share the positional structure — topic + anak(ne) at the left edge — but the fronted constituent varies: a possessed noun phrase, a relative-clause head, and a bare lexical noun. The register likewise varies: oral narrative, a modern written newsletter, and a generic statement in the same newsletter. The anak(ne) particle itself appears in different clause types and carries a pragmatic weight closer to Japanese '～に関しては (as for, regarding —)' than to the bare thematic は; once a topic is established in discourse, re-marking with anak on a continuing topic is unnecessary aynu-corpora Discord (2023–2026) (nukopoli, aynu-corpora Discord 2024-11-09; asserted; consistent with (Shibatani 1990: 38)). The full distributional and functional account of anak(ne) is in Chapter 140 (Topic and Focus Marking: anak(ne), patek, and ka).

The anak form is etymologically transparent: Tamura's Saru dictionary derives it from an-yak 'if it is so / as for it being' (reported in aynu-corpora Discord (2023–2026), nukopoli, aynu-corpora Discord 2023-12-08, asserted; after Tamura (1996)). This diachronic source is consistent with the particle's evidential weight and its less-grammaticalized status relative to Japanese は ‹speculative›.

Topic-initial order occurs without the overt particle when context already establishes the topic. The particle-free pattern is indistinguishable in position from neutral order or from unmarked focus preposing, and in practice it is the particle that signals topicalization as distinct from simple preverbal adjacency to the verb.

142.3 Focus preposing and allative-marked IO fronting

Left-fronting is available to focused constituents as well as to topics. Refsing observes that an indirect object, normally embedded among the preverbal NPs without any postpositional marking, "may, when stressed, be moved to the beginning of the sentence and marked with an allative case postposition" Refsing (1986) (§13.4.3, Shizunai data). The allative marking is the diagnostic: core arguments are never flagged by a case postposition in neutral order, so when one appears on a fronted IO it signals a positional operation driven by focus or contrast, not by grammatical role ‹contested›.

This pattern is phonologically and semantically driven — it signals narrow focus on the indirect-object referent. Content-question words, by contrast, remain in situ: they occupy the same preverbal position as the corresponding non-question constituent, and "questions do not involve any distinctive word order" Bugaeva (2012: 498). No wh-movement applies. The interrogative system — including the question particles ya and ya an and the content-question pro-forms (hunna 'who', hemanta 'what', hunak 'where') — is treated in Chapter 144 (Interrogative Strategies, Question Particles, and Evidential Questions).

In the majority of cases, focus is conveyed in situ through the focus particle ka 'also/even/indeed' or the exclusive adverb patek 'only', rather than by a positional operation. When a cleft or pseudocleft construction is used to identify a focus referent, the nominalization-based apparatus described in Chapter 141 (Cleft, Pseudocleft, and Nominalization-Based Focus) is employed; this chapter does not treat those constructions.

142.4 Right-dislocation and the afterthought construction

The mirror image of topic-initial order is a pattern documented by Bugaeva in which the predicate comes first and the disambiguating subject or object NP appears after the verb, re-predicated by the light verb ki ‘do’ Bugaeva (2022: ch.1 §4.3). Bugaeva analyses this as right-dislocation: a discourse or processing device that "mimics the verb-initial strategy of establishing relations at the outset" even in a verb-final language, allowing the hearer to know the event-type before the participant-identities are supplied. The following passage from a Chitose narrative has the predicate phrase he=tuk-pa pa 'they all grew (plural, perfective)' before the two subject NPs, which are then introduced as afterthoughts via the ki construction:

Bugaeva connects this pattern typologically to Nichols's observation that head-marking languages, in which relations are established on the verb rather than on NPs, have the greatest freedom to put the verb first — "establishing relations at the outset" — and that this is the functional pay-off of verb-initial order in many head-marking families (Nichols 1986: 104). Verb-final Ainu achieves a structurally parallel effect through right-dislocation: the event is predicated and the argument-tracking indices are on the verb; the NP appears afterward as a lexical specification that allows the hearer to recover participant identity Bugaeva (2022: ch.1 §7).

The pattern is attested but not quantified: only two examples are documented in the sources consulted (Bugaeva 2022 ch.1, exx.18–19), both from Chitose narrative texts, so its frequency and range are open ‹corpus-suggested›. No right-dislocation marker has grammaticalized; the ki that closes the afterthought is the ordinary light verb 'do', and the construction has no dedicated morphological signature distinct from any other ki-predicated clause. Its identification as right-dislocation rests on the discourse position of the NP relative to the preceding predicate.

The fourth-person affixes are central to what makes right-dislocation functional in Ainu narration. Third-person arguments carry a zero index — no morphological trace of their identity — and it is precisely this zero-marking that motivates the afterthought: the hearer cannot identify the participant from the affix and so the lexical NP is supplied after the fact. See Chapter 67 (The Indefinite/Fourth Person: Forms, Reference, and Agent-Defocusing) for the agent-defocusing and narrator-tracking functions of the fourth person, and Chapter 150 (First-Person Narration, the Logophoric Fourth Person, and Reported Discourse) for the broader discourse role of the a=/=an forms in oral narrative.

142.5 Adjunct placement and preverbal order

Time adverbs, manner adverbs, and postpositional adjunct phrases are all preverbal in Hokkaido Ainu, but their order within the preverbal domain is unconstrained. Nakagawa's sentence template allows zero to any number of adverbials (副詞句 0…x) in any order relative to one another and relative to the argument NPs (名詞句 0…n), with the only requirement being that all precede the verb phrase Nakagawa (2024: 361). Refsing states the same freedom empirically: her grammar does not account for adjunct order because she found it "very free" Refsing (1986) (§2.4). Negators somo ‘not (negating adverb)’ and iteki ‘don't (prohibitive adverb)’ likewise precede the verb as adverbs; they occupy no fixed structural slot beyond the general Adv–V requirement Nakagawa (2024: 365).

One specific pair of adverbial forms illustrates how adjunct order can be sensitive to contact-induced change. In traditional Ainu texts the complex ani patek '(INS) only' — the instrumental postposition ani following its nominal complement and followed by the exclusive adverb patek — is the normal sequence. Modern speakers show roughly equal frequency of the reverse order patek ani. The reversal is attributed to Japanese influence: patek is an adverb and cannot be nominalised as Japanese 丈/だけ can, so the Japanese-modelled patek ani sequence imports a word-order pattern that is category-inappropriate for the Ainu form aynu-corpora Discord (2023–2026) (nukopoli, aynu-corpora Discord 2024-12-16; proposed) ‹contested›.

142.6 Discourse conditions and the interaction with ellipsis

The positional operations described above are not alternatives to one another but alternatives to argument ellipsis. An argument NP that is fully recoverable from context — whether from a shared index on the verb, from the established discourse referent, or from plausibility — is simply absent: "it is not necessary in Ainu for a noun phrase that is clear from the context to appear in a sentence, and such a noun phrase is not even represented by a pronoun" Nakagawa (2024: 361). Fronting or topic-marking therefore signals something beyond what the obligatory person indices already convey. Typically it marks re-establishment of a topic after a scene-switch or topic-lapse, the introduction of a new referent that the hearer cannot retrieve from the index alone, or contrastive focus on a participant against an alternative set. See Chapter 139 (Reference Tracking and Argument Continuity) for the full system of how participant continuity is maintained across clauses.

The discourse function of each operation is approximate rather than categorical:

• Topic-initial with anak(ne) — marks a discourse-topic at the start of a new unit, after a gap, or when shifting from a previous topic; the particle has the weight of 'as for (X)' and is not re-applied on every subsequent mention of the same topic.
• In-situ order — the default when participants are known and the predicate is the communicative center; any preverbal arrangement is grammatical as long as roles are recoverable from the indices and context.
• Focus preposing with allative — reserved for the indirect object under narrow contrastive focus; the allative postposition is the marker that distinguishes this from ordinary topic-initial position.
• Right-dislocation with ki — supplies a participant lexically after the predicate has committed to an event-type; attested in narrative contexts where the third-person zero index is insufficient for disambiguation.

The interaction between information structure and the nonconfigurationality question is addressed in Chapter 94 (Pro-Drop, (Non)configurationality, and the Pronominal-Argument Debate). The head-marking analysis of Ainu (see Satō (2025: 359–365); (Nichols 1986: 104)) predicts precisely the observed pattern: because roles are encoded on the predicate, overt NPs are free to appear, be omitted, or be placed wherever information structure directs them. The clause-chaining apparatus — wa, hine, kor — maintains participant continuity across linked clauses and thereby reduces the need for topic re-introduction within a chain (see Chapter 131 (Clause Linkage in Ainu: Typology and Inventory)). Fronting and dislocation are most active at chain boundaries and at discourse transitions, not inside the chain itself.
