Ergative–absolutive alignment

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 ("subject") of a transitive verb.^[1] Examples include Basque, Georgian, Mayan, Tibetan, and certain Indo-European languages (such as Pashto and the Kurdish languages and many Indo-Aryan languages like Hindi–Urdu). It has also been attributed to the Semitic modern Aramaic (also called Neo-Aramaic) languages. Ergative languages are classified into two groups: those that are morphologically ergative but syntactically behave as accusative (for instance, Basque, Pashto and Urdu) and those that, on top of being ergative morphologically, also show ergativity in syntax. No language has been recorded in which both the morphological and syntactical ergative are present.^{[2][contradictory]} Languages that belong to the former group are more numerous than those to the latter. Dyirbal is said to be the only representative of syntactic ergativity, yet it displays accusative alignment with certain pronouns.^{[remove, correct, give citation, or clarification needed]}

The ergative-absolutive alignment is in contrast to nominative–accusative alignment, which is observed in English and most other Indo-European languages, where the single argument of an intransitive verb ("She" in the sentence "She walks") behaves grammatically like the agent (subject) of a transitive verb ("She" in the sentence "She finds it") but different from the object of a transitive verb ("her" in the sentence "He likes her"). When ergative–absolutive alignment is coded by grammatical case, the case used for the single argument of an intransitive verb and the object of a transitive verb is the absolutive, and the case used for the agent of a transitive verb is the ergative. In nominative-accusative languages, the case for the single argument of an intransitive verb and the agent of a transitive verb is the nominative, while the case for the direct object of a transitive verb is the accusative.

Many languages have ergative–absolutive alignment only in some parts of their grammar (e.g., in the case marking of nouns), but nominative-accusative alignment in other parts (e.g., in the case marking of pronouns, or in person agreement). This is known as split ergativity.

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. Such languages are said to operate with S/O syntactic pivot.

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. Such languages are said to operate with S/A (syntactic) pivot.

Ergative alignment (intransitive Subject and transitive Object treated the same way) displaying S/O pivot

Accusative alignment (intransitive Subject and transitive Agent treated the same way) displaying S/A pivot

(reference for figure:^[3])

These different arguments are usually symbolized as follows:

• A = agent of transitive verb
• O = object of transitive verb (also symbolized as P for "patient")
• S = core argument (i.e. subject) of intransitive verb

The relationship between ergative and accusative systems can be schematically represented as the following:

	Ergative–absolutive	Nominative–accusative
A	ERG	NOM
O	ABS	ACC
S	ABS	NOM

See morphosyntactic alignment for a more technical explanation and a comparison with nominative–accusative languages.

The word subject, as it is typically defined in grammars of nominative-accusative languages, has a different application when referring to ergative–absolutive languages, or when discussing morphosyntactic alignment in general.

Ergative languages tend to be either verb-final or verb-initial; there are few, if any, ergative SVO-languages.^[4]

Realization of ergativity

Ergativity can be found in both morphological and syntactic behavior.^[5]

Morphological ergativity

If the language has morphological case, then the verb arguments are marked thus:

• 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.^[3]

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 a verbal agreement structure that is ergative. In languages with ergative–absolutive agreement systems, the absolutive form is usually the most unmarked form of a word (exceptions include Nias and Tlapanec).^[6]

The following examples from Basque demonstrate an ergative–absolutive case marking system:

Ergative language
Sentence:	Martin etorri da.			Martinek Diego ikusi du.
Word:	Martin-Ø	etorri da		Martin-ek	Diego-Ø	ikusi du
Gloss:	Martin-ABS	has arrived		Martin-ERG	Diego-ABS	has seen
Function:	S	VERBintrans		A	O	VERBtrans
Translation:	"Martin has arrived."			"Martin has seen Diego."

Here -Ø represents a zero morpheme, as the absolutive case is unmarked in Basque. The forms for the ergative are -k after a vowel, and -ek after a consonant. It is a further rule in Basque grammar that in most cases a noun phrase must be closed by a determiner. The default determiner (commonly called the article, which is suffixed to common nouns and usually translatable by "the" in English) is -a in the singular and -ak in the plural, the plural being marked only on the determiner and never the noun. For common nouns, this default determiner is fused with the ergative case marker. Thus one obtains the following forms for gizon ("man"): gizon-a (man-the.sing.abs), gizon-ak (man-the.pl.abs), gizon-ak (man-the.sing.erg), gizon-ek (man-the.pl.erg). When fused with the article, the absolutive plural is homophonous with the ergative singular. See Basque grammar for details.^[7]

In contrast, Japanese is a nominative–accusative language:

Accusative language
Sentence:	男の人が着いた Otokonohito ga tsuita.			男の人がこどもを見た Otokonohito ga kodomo o mita.
Words:	otokonohito ga	tsuita		otokonohito ga	kodomo o	mita
Gloss:	man NOM	arrived		man NOM	child ACC	saw
Function:	S	VERBintrans		A	O	VERBtrans
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 one sets: 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:

	accusative English (S form = A form)			hypothetical ergative English (S form = O form)
word order	SVO			SOV			VOS
transitive	nominative A		accusative O	ergative A	absolutive O			absolutive O	ergative A
	He	kisses	her.	He	her	kisses.	Kisses	her	he.
	She	kisses	him.	She	him	kisses.	Kisses	him	she.
intransitive	nominative S			absolutive S					absolutive S
	He	smiles.		Him		smiles.	Smiles		him.
	She	smiles.		Her		smiles.	Smiles		her.

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.

Georgian has an ergative alignment, but the agent is only marked with the ergative case in the perfective aspect (also known as the "aorist screeve"). Compare:

K'aci vašls č'ams. (კაცი ვაშლს ჭამს) "The man is eating an apple."

K'acma 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'aci ). 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'acma 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.

Differing noun-pronoun alignment

In rare cases, such as the Australian Aboriginal language Nhanda, different nominal elements may follow a different case-alignment template. In Nhanda, common nouns have ergative-absolutive alignment—like in most Australian languages—but most pronouns instead follow a nominative-accusative template. In Nhanda, absolutive case has a null suffix while ergative case is marked with some allomorph of the suffixes -nggu or -lu. See the common noun paradigm at play below:^[8]

Intransitive Subject (ABS)

pundu

rain.ABS

yatka-yu

go-ABL.NFUT

pundu yatka-yu

rain.ABS go-ABL.NFUT

Rain is coming.

nyarlu-nggu

woman-ERG

yawarda

kangaroo.ABS

nha-'i

see-PAST

nyarlu-nggu yawarda nha-'i

The woman saw the kangaroo

Compare the above examples with the case marking of pronouns in Nhanda below, wherein all subjects (regardless of verb transitivity) are marked (in this case with a null suffix) the same for case while transitive objects take the accusative suffix -nha.

Intransitive Pronoun Subject (NOM)

Syntactic ergativity

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
• Subordination
• Switch reference

Example

Example of syntactic ergativity in the "conjunction reduction" construction (coordinated clauses) in Dyirbal in contrast with English conjunction reduction. (The subscript (i) indicates coreference.)

English (SVO word order):

1. Father returned.
2. Father saw mother.
3. Mother saw father.
4. Father_(i) returned and father_(i) saw mother.
5. Father_(i) returned and _____(i) saw mother.
6. Father_(i) returned and mother saw father_(i).
7. * Father_(i) returned and mother saw _____(i). (ill-formed, because S and deleted O cannot be coreferential.)

Dyirbal (OSV word order):

1. Ŋuma banagan^yu. (Father returned.)
2. Yabu ŋumaŋgu buṛan. (lit. Mother father-ŋgu saw, i.e. Father saw mother.)
3. Ŋuma yabuŋgu buṛan. (lit. Father mother-ŋgu saw, i.e. Mother saw father.)
4. Ŋuma_(i) banagan^yu, yabu ŋumaŋgu_(i) buṛan. (lit. Father_(i) returned, mother father-ŋgu_(i) saw, i.e. Father returned, father saw mother.)
5. * Ŋuma_(i) banagan^yu, yabu _____(i) buṛan. (lit. *Father_(i) returned, mother _____(i) saw; ill-formed, because S and deleted A cannot be coreferential.)
6. Ŋuma_(i) banagan^yu, ŋuma_(i) yabuŋgu buṛan. (lit. Father_(i) returned, father_(i) mother-ŋgu saw, i.e. Father returned, mother saw father.)
7. Ŋuma_(i) banagan^yu, _____(i) yabuŋgu buṛan. (lit. Father_(i) returned, _____(i) mother-ŋgu saw, i.e. Father returned, mother saw father.)

Crucially, the fifth sentence has an S/A pivot and thus is ill-formed in Dyirbal (syntactically ergative); on the other hand, the seventh sentence has an S/O pivot and thus is ill-formed in English (syntactically accusative).

Split ergativity

Main article: Split ergativity

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 case-marking and verbal agreement, though it shows thoroughly nominative–accusative syntactic alignment.^[9]

In Hindustani (Hindi and Urdu), the ergative case is marked on agents in the perfective aspect for transitive and ditransitive verbs (also for intransitive verbs when they are volitional),^[10] while in other situations agents appear in the nominative case.

In the Northern Kurdish language Kurmanji, the ergative case is marked on agents and verbs of transitive verbs in past tenses, for the events actually occurred in the past. Present, future and "future in the past" tenses show no ergative mark neither for agents nor the verbs. For example:

(1) Ez diçim. (I go)

(2) Ez wî dibînim. (I see him.)

(3) Ew diçe. (He goes)

(4) Ew min dibîne. (He sees me.)

but:

(5) Ez çûm. (I went)

(6) Min ew dît. (I saw him.)

(7) Ew çû. (He went.)

(8) Wî ez dîtim. (He saw me.)

In sentences (1) to (4), there is no ergativity (transitive and intransitive verbs alike). In sentences (6) and (8), the ergative case is marked on agents and verbs.

In Dyirbal, pronouns are morphologically nominative–accusative when the agent is first or second person, but ergative when the agent is a third person.

Optional ergativity

Many languages with ergative marking display what is known as optional ergativity, where the ergative marking is not always expressed in all situations. McGregor (2010) gives a range of contexts when we often see optional ergativity, and argues that the choice is often not truly optional but is affected by semantics and pragmatics. Unlike split ergativity, which occurs regularly but in limited locations, optional ergativity can occur in a range of environments, but may not be used in a way that appears regular or consistent.

Optional ergativity may be motivated by:

• The animacy of the subject, with more animate subjects more likely to be marked ergative
• The semantics of the verb, with more active or transitive verbs more likely to be marked ergative
• The grammatical structure or [tense-aspect-mood]

Languages from Australia, New Guinea and Tibet have been shown to have optional ergativity.^[11]

Distribution of ergative languages

Prototypical ergative languages are, for the most part, restricted to specific regions of the world: Mesopotamia (Kurdish, and some extinct languages), the Caucasus, the Americas, the Tibetan Plateau, and Australia and parts of New Guinea.

Specific languages and language families include:

Americas

• Chibchan languages
• Chinookan languages (extinct)
• Coosan languages^[12] (extinct)
• Eskimo–Aleut languages
• Guaicuruan languages
• Macro-Jê languages
• Mayan
• Mixe–Zoque
• Panoan languages
• Salish languages
• Tsimshian

Africa

• Tedaga, a Nilo-Saharan language of Southern Libya and Northern Chad.
• Majang language, a Nilo-Saharan language of Ethiopia.
• Päri, although recent studies imply a nominative-accusative system.^[13]

Asia

• Assamese
• Burushaski
• Chukchi^[14] (endangered)
• Hawu^[15]
• Tibetan
• Sylheti
• Yaghnobi
• Pashto

Australian

• Most Australian Aboriginal languages, such as Dyirbal

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 tripartite languages or ergative–accusative languages.

Papua

• Eastern Trans-Fly languages
• various Trans–New Guinea languages

Europe

• Basque

Caucasus and Near East

• Hurrian (extinct)
• Urartian (extinct)
• Sumerian (extinct)^[16]
• South Caucasian: Georgian, Laz
• Northeast Caucasian: Chechen, Lezgian, Tsez, Archi (endangered)
• Northwest Caucasian: Abkhaz, Circassian, Ubykh (extinct)
• Kurdish: Gorani,^[17] Zazaki,^[18][19][20] Sorani^{[21][22][23][24][25]} and Kurmanji^[26][27][28]

Several scholars have hypothesized that Proto-Indo-European was an ergative language, although this hypothesis is controversial.^[29]

Languages with limited ergativity

• In Hindi (Indo-Aryan), ergative alignment occurs only when the verb is in the perfective aspect for transitive verbs (also for intransitive verbs but only when they are volitional).
• In Pashto, ergative alignment occurs only in the past tense.
• In 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 symmetrical voice.
• In the Neo-Aramaic languages, which are generally classified into 4 groups, only Northeastern (NENA) and Ṭuroyo groups exhibit split ergativity, which is formed in the perfective aspect only, whereas the imperfective aspect is nominative-accusative. Some dialects would only mark unaccusative subjects as ergative. Assyrian Neo-Aramaic, in particular, has an ergative type of construction of the perfective past verbal base, where foregone actions are verbalized by a passive construction with the patient being conferred as the grammatical subject rather than by an active construction, e.g. baxta qtile ("the woman was killed by him"). The ergative type of inflection with an agentive phrase has been extended by analogy to intransitive verbs, e.g. qim-le ("he has risen").^[30] Aramaic has historically been a nominative-accusative language.^[31]

Sign languages

Sign languages (for example, Nepali Sign Language) should also generally be considered ergative in the patterning of actant incorporation in verbs.^[32] In sign languages that 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)^[33] this ergative-absolutive patterning 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.)

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 certain intransitive verbs, 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:

"Susie employs Mike" → "Mike 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.

When English nominalizes a clause, the underlying subject of an intransitive verb and the underlying object of a transitive verb are both marked with the possessive case or with the preposition "of" (the choice depends on the type and length of the noun: pronouns and short nouns are typically marked with the possessive, while long and complex NPs are marked with "of"). The underlying subject of a transitive is marked differently (typically with "by" as in a passive construction):

"(a dentist) extracts a tooth" → "the extraction of a tooth (by a dentist)"

"(I/The editor) revised the essay" → "(my/the editor's) revision of the essay"

"(I was surprised that) the water boiled" → "(I was surprised at) the boiling of the water"

"I departed on time (so I could catch the plane)" → "My timely departure (allowed me to catch the plane)"
