An ergative–absolutive language (or simply an ergative language) is a language in which the single argument ("subject") of an intransitive verb behaves like the object of a transitive verb, and differently from the agent ("subject") of a transitive verb. For instance, instead of saying "I moved her" and "she moved", speakers of an ergative language would say the equivalent of "I moved her" and "her moved".
Ergative vs. accusative languages
An ergative language maintains a syntactic or morphological equivalence (such as the same word order or grammatical case) for the object of a transitive verb and the single core argument of an intransitive verb, while treating the agent of a transitive verb differently.
This contrasts with nominative–accusative languages such as English, where the single argument of an intransitive verb and the agent of a transitive verb (both called the subject) are treated alike and kept distinct from the object of a transitive verb.
These different arguments are usually symbolized as follows:
- O = object of transitive verb (also symbolized as P for "patient")
- S = core argument of intransitive verb
- A = agent of transitive verb
The relationship between ergative and accusative systems can be schematically represented as the following:
Note that the word subject, as it is typically defined in grammars of nominative–accusative languages, is inapplicable when referring to ergative–absolutive languages, or when discussing morphosyntactic alignment in general.
Realization of ergativity
- The agent of a transitive verb (A) is marked as ergative case, or as a similar case such as oblique.
- The core argument of an intransitive verb (S) and the object of a transitive verb (O) are both marked with absolutive case.
If there is no case marking, ergativity can be marked through other means, such as in verbal morphology. For instance, Abkhaz and most Mayan languages have no morphological ergative case, but they have verbal agreement structure which is ergative. In languages with ergative–absolutive agreement systems, the absolutive form is usually the most unmarked form of a word.
|Sentence:||Gizona etorri da.||Gizonak mutila ikusi du.|
|Word:||gizon-a||etorri da||gizon-ak||mutil-a||ikusi du|
|Translation:||"The man has arrived."||"The man saw the boy."|
In Basque, gizon is "man" and mutil is "boy". Gizon has a different case marking depending on whether it is the argument of a transitive or intransitive verb: the absolutive case, -a, and ergative case, -ak. In contrast, the core argument of the intransitive clause and the object of the transitive clause have the same absolutive case.
In contrast, Japanese is a nominative–accusative language:
|Sentence:||Otoko ga tsuita.||Otoko ga kodomo o mita.|
|Words:||otoko ga||tsuita||otoko ga||kodomo o||mita|
|Gloss:||man NOM||arrived||man NOM||child ACC||saw|
|Translation:||"The man arrived."||"The man saw the child."|
In this language, the argument of the intransitive and agent of the transitive sentence are marked with the same nominative case particle ga, while the object of the transitive sentence is marked with the accusative case o.
If we set: A = agent of a transitive verb; S = argument of an intransitive verb; O = object of a transitive verb, then we can contrast normal nominative–accusative English with a hypothetical ergative English:
- I (S) traveled; She (S) traveled.
- I (A) invited her (O) to go with me; She (A) invited me (O) to go with her.
(S form = A form)
Hypothetical ergative English:
- Me (S) traveled; Her (S) traveled.
- I (A) invited her (O) to go with me; She (A) invited me (O) to go with her.
(S form = O form)
A number of languages have both ergative and accusative morphology. A typical example is a language that has nominative–accusative marking on verbs and ergative–absolutive case marking on nouns.
- K'ac'i vašls č'ams. (კაცი ვაშლს ჭამს) "The man is eating an apple."
- K'ac'ma vašli č'ama. (კაცმა ვაშლი ჭამა) "The man ate an apple."
K'ac'- is the root of the word "man". In the first sentence (present continuous tense) the agent is in the nominative case (k'ac'i). In the second sentence, which shows ergative alignment, the root is marked with the ergative suffix -ma.
However, there are some intransitive verbs in Georgian that behave like transitive verbs, and therefore employ the ergative case in the past tense. Consider:
- K'ac'ma daacemina. (კაცმა დააცემინა) "The man sneezed."
Although the verb sneeze is clearly intransitive, it is conjugated like a transitive verb. In Georgian there are a few verbs like these, and there has not been a clear-cut explanation as to why these verbs have evolved this way. One explanation is that verbs such as "sneeze" used to have a direct object (the object being "nose" in the case of "sneeze") and over time lost these objects, yet kept their transitive behavior.
Ergativity may be manifested through syntax, such as saying “Arrived I” for “I arrived”, in addition to morphology. Syntactic ergativity is quite rare, and while all languages that exhibit it also feature morphological ergativity, few morphologically ergative languages have ergative syntax. As with morphology, syntactic ergativity can be placed on a continuum, whereby certain syntactic operations may pattern accusatively and others ergatively. The degree of syntactic ergativity is then dependent on the number of syntactic operations that treat the subject like the object. Syntactic ergativity is also referred to as inter-clausal ergativity, as it typically appears in the relation of two clauses.
Syntactic ergativity may appear in:
- Word order (for example, the absolutive argument comes before the verb and the ergative argument comes after it)
- Syntactic pivots
- Relative clauses – determining which arguments are available for relativization
- Switch reference

The term ergative–absolutive is considered unsatisfactory by some, since there are very few languages without any patterns that exhibit nominative–accusative alignment. Instead they posit that one should only speak of ergative–absolutive systems, which languages employ to different degrees.
Many languages classified as ergative in fact show split ergativity, whereby syntactic and/or morphological ergative patterns are conditioned by the grammatical context, typically person or the tense/aspect of the verb. Basque is unusual in having an almost fully ergative system.

In Dyirbal, pronouns are morphologically nominative–accusative when the agent is first or second person, but ergative when the agent is a third person.
Distribution of ergative languages
Some specific languages are the following:
Caucasus and Mesopotamia
- Hurrian (extinct)
- Urartian (extinct)
- Sumerian (extinct)
- South Caucasian: Georgian, Laz...
- Northeast Caucasian: Chechen, Lezgic...
- Northwest Caucasian: Circassian...
- Kurdish: Gorani Zazaki, Sorani and Kurmanji. The Zazaki, Gorani, Sorani, and Kurmanji are the only ergative languages of the Iranian language family.
- Chibchan languages
- Chinook languages
- Eskimo–Aleut languages
- Panoan languages (Peru, Brazil, Bolivia), e.g. Shipibo-Conibo
Certain Australian Aboriginal languages (e.g., Wangkumara) possess an intransitive case and an accusative case along with an ergative case, and lack an absolutive case; such languages are called ergative–accusative languages or tripartite languages.
Sign languages (for example, Nepali Sign Language) should also generally be considered ergative in the patterning of actant incorporation in verbs. In sign languages which have been studied, classifier handshapes are incorporated into verbs, indicating the subject of intransitive verbs when incorporated, and the object of transitive verbs. (If we follow the "Semantic Phonology" model proposed by William Stokoe(1991) this ergative-absolutive paterning also works at the level of the lexicon: thus in Nepali Sign Language the sign for TEA has the motion for the verb DRINK with a manual alphabet handshape च /ca/ (standing for the first letter of the Nepali word TEA चिया /chiya:/) being incorporated as the object.)
Many other languages have limited ergativity. In both Pashto and Hindi (Indo-Iranian), ergative behavior occurs only in the preterite and perfect tenses, and in the Georgian, ergativity only occurs in the perfective.
The Philippine languages (e.g., Tagalog) are sometimes considered ergative (Schachter 1976, 1977; Kroeger 1993), however they have also been considered to have their own unique morphosyntactic alignment. See Austronesian alignment.
Several scholars have hypothesized that Proto-Indo-European was an Ergative language. However, this hypothesis is disputed. 
Approximations of ergativity in English
English has derivational morphology that parallels ergativity in that it operates on intransitive verbs and objects of transitive verbs. With an intransitive verb, adding the suffix -ee to the verb produces a label for the person performing the action:
- "John has retired" → "John is a retiree"
- "John has escaped" → "John is an escapee"
However, with a transitive verb, adding -ee does not produce a label for the person doing the action. Instead, it gives us a label for the person to whom the action is done:
- "Mike employs Susie" → "Susie is an employee"
- "Mike has appointed Susie" → "Susie is an appointee"
Etymologically, the sense in which "-ee" denotes the object of a transitive verb is the original one, arising from French past participles in "-é". This is still the prevalent sense in British English: the intransitive uses are all 19th-century American coinages and all except "escapee" are still marked as "chiefly U.S." by the Oxford English Dictionary.
English also has a number of so-called ergative verbs, where the object of the verb when transitive is equivalent to the subject of the verb when intransitive.
