In linguistic typology, tripartite alignment is a type of morphosyntactic alignment in which the main argument ('subject') of an intransitive verb, the agent argument ('subject') of a transitive verb, and the patient argument ('direct object') of a transitive verb are each treated distinctly in the grammatical system of a language. [1] This is in contrast with nominative-accusative and ergative-absolutive alignment languages, in which the argument of an intransitive verb patterns with either the agent argument of the transitive (in accusative languages) or with the patient argument of the transitive (in ergative languages). Thus, whereas in English, "she" in "she runs" patterns with "she" in "she finds it", and an ergative language would pattern "she" in "she runs" with "her" in "he likes her", a tripartite language would treat the "she" in "she runs" as morphologically and/or syntactically distinct from either argument in "he likes her".
Which languages constitute genuine examples of a tripartite case alignment is a matter of debate; [2] however, Wangkumara, Nez Perce, Ainu, Vakh dialects of Khanty, Semelai, Kalaw Lagaw Ya, Kham, and Yazghulami have all been claimed to demonstrate tripartite structure in at least some part of their grammar. [3] [4] [5] [6] While tripartite alignments are rare in natural languages, [1] they have proven popular in constructed languages, notably the Na'vi language featured in 2009's Avatar .
In languages with morphological case, a tritransitive alignment typically marks the agent argument of a transitive verb with an ergative case, the patient argument of a transitive verb with the accusative case, and the argument of an intransitive verb with an intransitive case.
A tripartite language does not maintain any syntactic or morphological equivalence (such as word order or grammatical case) between the core argument of intransitive verbs and either core argument of transitive verbs. In full tripartite alignment systems, this entails the agent argument of intransitive verbs always being treated differently from each of the core arguments of transitive verbs, whereas for mixed system intransitive alignment systems this may only entail that certain classes of noun are treated differently between these syntactic positions. [1]
The arguments of a verb are usually symbolized as follows:
The relationship between accusative, ergative, and tripartite alignments can be schematically represented as follows:
Ergative-Absolutive | Nominative-Accusative | Tripartite | |
---|---|---|---|
A | ERG | NOM | ERG |
O | ABS | ACC | ACC |
S | ABS | NOM | INTR |
See morphosyntactic alignment for a more technical explanation.
The term 'subject' has been found to be problematic when applied to languages which have any morphosyntactic alignment other than nominative-accusative, and hence, reference to the 'agent' argument of transitive sentences is preferred to the term 'subject'. [7]
Languages may be designated as tripartite languages in virtue of having either a full tripartite morphosyntactic alignment, or in virtue of having a mixed system which results in tripartite treatment of one or more specific classes of nouns. [1]
A full tripartite system distinguishes between S, A and O arguments in all classes of nominals. [1] It has been claimed that Wangkumara has the only recorded full tripartite alignment system. [3] [8] [1]
Wangkumara consistently differentiates marking on S, A, and O arguments in the morphology, as demonstrated in example (1) below: [9]
karn-ia
man-NOM
yanthagaria
walk.PRES
makurr-anrru
stick-INSTR
'The man walks with a stick.'
karna-ulu
man-ERG
kalkanga
hit.PAST
thithi-nhanha
dog-ACC.NONM.SG
'The man hit the (female) dog.'
In the above example, the intransitive case in (a) is glossed NOM, in accordance with Breen's original transcription. Across (1), we see differential case suffixes for each of intransitive (NOM), ergative (ERG), and accusative (ACC) case. [10]
The same tripartite distinction is clear in the pronominal system: [11]
Palu-nga
die-PAST
nganyi
1sg.NOM
"I died."
Ngkatu
1sg.ERG
nhanha
3sg.ABS
kalka-nga
hit-PAST
"I hit him/her."
Nulu
3sg.ERG
nganha
1sg.ABS
kalka-ng
hit-PAST
"S/he hit me."
In the above examples, we see the first person singular pronoun taking different forms for each of the S, A, and O arguments (marked NOM, ERG and ABS respectively), indicating the tripartite alignment in pronominal morphology.
Syntactic surveys of Wangkumara suggest this is generally true of the language as a whole. [3] Hence, Wangkumara represents a case of a full tripartite alignment.
More common than full tripartite systems, mixed system tripartite alignments either demonstrate tripartite alignment in some subsection of the grammar, or else lacks the ergative, the accusative, or both in some classes of nominals. [1] An example of the former kind of mixed system may be Yazghulami, which exhibits tripartite alignment but only in the past tense. [6] An example of the latter would be Nez Perce, which lacks ergative marking in the first and second person. [1]
The following examples from Nez Perce illustrate the intransitive-ergative-accusative opposition that holds in the third person: [12]
Hi-páay-na
3SG-arrive-PERF
háama-Ø
man.NOM
'The man arrived.'
Háamap-im
man-ERG
'áayato-na
woman-ACC
pée-'nehne-ne
3SG-3SG-take-PERF
'The man took the woman away.'
In the above examples, (2a) demonstrates the intransitive case marking (here coded as NOM), while (2b) demonstrates differential ergative and accusative markings. Thus, Nez Perce demonstrates tripartite differentiations in its third person morphology.
Ainu also shows the passive voice formation typical of nominative-accusative languages and the antipassive of ergative-absolutive languages. Like Nez Percé, the use of both the passive and antipassive is a trait of a tripartite language.

In grammar, the ergative case is the grammatical case that identifies a nominal phrase as the agent of a transitive verb in ergative–absolutive languages.
A grammatical case is a category of nouns and noun modifiers which corresponds to one or more potential grammatical functions for a nominal group in a wording. In various languages, nominal groups consisting of a noun and its modifiers belong to one of a few such categories. For instance, in English, one says I see them and they see me: the nominative pronouns I/they represent the perceiver and the accusative pronouns me/them represent the phenomenon perceived. Here, nominative and accusative are cases, that is, categories of pronouns corresponding to the functions they have in representation.
In grammar, the absolutive case is the case of nouns in ergative–absolutive languages that would generally be the subjects of intransitive verbs or the objects of transitive verbs in the translational equivalents of nominative–accusative languages such as English.
In grammar, an intransitive verb is a verb whose context does not entail a direct object. That lack of transitivity distinguishes intransitive verbs from transitive verbs, which entail one or more objects. Additionally, intransitive verbs are typically considered within a class apart from modal verbs and defective verbs.
In linguistic typology, split ergativity is a feature of certain languages where some constructions use ergative syntax and morphology, but other constructions show another pattern, usually nominative–accusative. The conditions in which ergative constructions are used varies among different languages.
The antipassive voice is a type of grammatical voice that either does not include the object or includes the object in an oblique case. This construction is similar to the passive voice, in that it decreases the verb's valency by one – the passive by deleting the agent and "promoting" the object to become the subject of the passive construction, the antipassive by deleting the object and "promoting" the agent to become the subject of the antipassive construction.
In linguistics, morphosyntactic alignment is the grammatical relationship between arguments—specifically, between the two arguments of transitive verbs like the dog chased the cat, and the single argument of intransitive verbs like the cat ran away. English has a subject, which merges the more active argument of transitive verbs with the argument of intransitive verbs, leaving the object distinct; other languages may have different strategies, or, rarely, make no distinction at all. Distinctions may be made morphologically, syntactically, or both.
In linguistic typology, ergative–absolutive alignment is a type of morphosyntactic alignment in which the single argument ("subject") of an intransitive verb behaves like the object of a transitive verb, and differently from the agent of a transitive verb. Examples include Basque, Georgian, Mayan, Tibetan, and certain Indo-European languages. It has controversially also been attributed to the Semitic modern Aramaic languages.
In linguistic typology, nominative–accusative alignment is a type of morphosyntactic alignment in which subjects of intransitive verbs are treated like subjects of transitive verbs, and are distinguished from objects of transitive verbs in basic clause constructions. Nominative–accusative alignment can be coded by case-marking, verb agreement and/or word order. It has a wide global distribution and is the most common alignment system among the world's languages. Languages with nominative–accusative alignment are commonly called nominative–accusative languages.
In linguistics, a causative is a valency-increasing operation that indicates that a subject either causes someone or something else to do or be something or causes a change in state of a non-volitional event. Normally, it brings in a new argument, A, into a transitive clause, with the original subject S becoming the object O.
In linguistic typology, active–stative alignment is a type of morphosyntactic alignment in which the sole argument ("subject") of an intransitive clause is sometimes marked in the same way as an agent of a transitive verb but other times in the same way as a direct object. Languages with active–stative alignment are often called active languages.
In linguistics, an unaccusative verb is an intransitive verb whose grammatical subject is not a semantic agent. In other words, the subject does not actively initiate, or is not actively responsible for, the action expressed by the verb. An unaccusative verb's subject is semantically similar to the direct object of a transitive verb or to the subject of a verb in the passive voice.
Hindustani, the lingua franca of Northern India and Pakistan, has two standardised registers: Hindi and Urdu. Grammatical differences between the two standards are minor but each uses its own script: Hindi uses Devanagari while Urdu uses an extended form of the Perso-Arabic script, typically in the Nastaʿlīq style.
A direct case is a grammatical case used with all three core relations: both the agent and patient of transitive verbs and the argument of intransitive verbs, though not always at the same time. The direct case contrasts with other cases in the language, typically oblique or genitive.
Canela is a dialect of the Canela-Krahô language, a Timbira variety of the Northern Jê language group spoken by the Apànjêkra (Apaniêkrá) and by the Mẽmõrtũmre in Maranhão, Brazil.
Mẽbêngôkre, sometimes referred to as Kayapó is a Northern Jê language spoken by the Kayapó and the Xikrin people in the north of Mato Grosso and Pará in Brazil. There are around 8,600 native speakers since 2010 based on the 2015 Ethnologue 18th edition. Due to the number of speakers and the influence of Portuguese speakers, the language stands at a sixth level of endangerment; in which the materials for literacy and education in Mẽbêngôkre are very limited.
Mori Bawah, also known as Lower Mori or East Mori, is an Austronesian language of the Celebic branch. It is one of the principal languages of the Morowali Regency in Central Sulawesi.
In generative linguistics, Burzio's generalization is the observation that a verb can assign a theta role to its subject position if and only if it can assign an accusative case to its object. Accordingly, if a verb does not assign a theta role to its subject, then it does not assign accusative case to its object. The generalization is named after Italian linguist Luigi Burzio, based on work published in the 1980s, but the seeds of the idea are found in earlier scholarship. The generalization can be logically written in the following equation:
θ ↔ A Where: θ = Subject Theta Role A = Accusative Case
In linguistic typology, transitive alignment is a type of morphosyntactic alignment used in a small number of languages in which a single grammatical case is used to mark both arguments of a transitive verb, but not with the single argument of an intransitive verb. Such a situation, which is quite rare among the world's languages, has also been called a double-oblique clause structure.
In linguistic typology, nominative–absolutive alignment is a type of morphosyntactic alignment in which the sole argument of an intransitive verb shares some coding properties with the agent argument of a transitive verb and other coding properties with the patient argument of a transitive verb. It is typically observed in a subset of the clause types of a given language.
