Ergativity can be found in both
morphological and
syntactic behavior.
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.
Basque The following examples from
Basque demonstrate an ergative–absolutive case marking system: Here
-Ø represents a
zero morpheme, as the absolutive case is unmarked in Basque with proper nouns (i.e., Martin, Diego, Berlin...). 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.
Circassian Conlang English English pronouns change depending on if they are used in the nominative or accusative cases. The third person singular pronoun, "he/she" is used in the nominative case, while "him/her" is used in the accusative. As these cases do not exist in ergative languages, they will be mapped to cases in the ergative–absolutive system for this example. "He/she" is represented here as the ergative, and "him/her" as the absolutive. Note how the key difference between these systems is that "him smiles" is grammatical in the hypothetical ergative English because it is aligned with how objects are used in transitive sentences.
Georgian 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"). Thus exhibiting a form of
split ergativity. Compare: : () "The man is eating an apple." : () "The man ate an apple." is the root of the word "man". In the first sentence (present continuous tense) the agent is in the nominative case ( ). In the second sentence, which shows ergative alignment, the root is marked with the ergative suffix . However, there are some intransitive verbs in Georgian that behave like transitive verbs, and therefore employ the ergative case in the past tense. Consider: : () "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, the
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:
Intransitive Subject (ABS) Transitive Subject-Object (ERG-ABS) 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) Transitive Pronoun Subject-Object (NOM-ACC) Syntactic ergativity Ergativity may be manifested through syntax in addition to morphology. While all known ergative languages show ergativity in their morphology, only a small portion also show ergativity in their 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): • Father returned. • Father saw mother. • Mother saw father. • Father(i) returned and father(i) saw mother. • Father(i) returned and ____(i) saw mother. • Father(i) returned and mother saw father(i). • Father(i) returned and mother saw ____(i). (ill-formed, because S and deleted O cannot be
coreferential.)
Dyirbal (
OSV word order): • Ŋuma banaganyu. (
Father returned.) • Yabu ŋumaŋgu buṛan. (lit.
Mother father-ŋgu
saw, i.e.
Father saw mother.) • Ŋuma yabuŋgu buṛan. (lit.
Father mother-ŋgu
saw, i.e.
Mother saw father.) • Ŋuma(i) banaganyu, yabu ŋumaŋgu(i) buṛan. (lit.
Father(i)
returned, mother father-ŋgu(i)
saw, i.e.
Father returned, father saw mother.) • Ŋuma(i) banaganyu, yabu ____(i) buṛan. (lit. *
Father(i)
returned, mother ____(i)
saw; ill-formed, because S and deleted A cannot be coreferential.) • Ŋuma(i) banaganyu, ŋuma(i) yabuŋgu buṛan. (lit.
Father(i)
returned, father(i)
mother-ŋgu
saw, i.e.
Father returned, mother saw father.) • Ŋuma(i) banaganyu, ____(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 Few ergative languages are purely ergative. Many ergative systems have parts of their grammar which do not maintain an ergative pattern, a phenomenon known as split ergativity. Some linguists have claimed that all ergative languages have split ergativity. The two main areas of grammar that often exhibit a split in ergativity are
grammatical person and
grammatical aspect. In both, cross-linguistic patterns have been observed which make the split of ergativity more predicable. With grammatical person, a directional hierarchy has been observed cross-linguistically which constricts which grammatical persons may exhibit ergativity in the same language. In languages following this pattern of split ergativity, there will be a particular point on the hierarchy in which everything to the left will exhibit ergativity, and everything to the right will not. For example,
Dyirbal has split ergativity on grammatical person and divides the hierarchy at the point of 1st/2nd person pronouns. 1st/2nd person pronouns use an accusative pattern, and everything to the left of it on the spectrum follows an ergative pattern. The same principle has been observed with grammatical aspect. The directionality hierarchy is as follows:
In Hindustani 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), while in other situations agents appear in the
nominative case.
In Kurmanji 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.
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. ==Distribution of ergative languages==
