Direct–inverse alignment

The existence of direct–inverse morphosyntax is usually accompanied by proximate–obviative morphosyntax. The direct–inverse dimension subsumes the proximate–obviative dimension. Across languages, obviation almost always involves the third person (although second-person obviation is reported for some Nilo-Saharan languages), and the direct–inverse alternation is usually presented as being a way of marking the proximate–obviative distinction between two (or more) third-person arguments of a sentence. However, there are at least two languages with inverse systems, the Mesoamerican languages Zoque and Huastec, in which inverse morphosyntax is never used when both subject and object are third person but only when one of the arguments is third person, and the other is a speech act participant (SAP), the first or second person.

Morphosyntactic variation across inverse-type languages

Neither a morphological feature nor a syntactic feature is common to all inverse systems.

Direct-inverse systems on verbs coexist with the various morphosyntactic alignments in nouns. In some inverse languages, including all Mesoamerican inverse languages, the direct-inverse alternation changes the morphosyntactic alignment, and the language is said to have hierarchical alignment.

Klaiman has suggested four common properties of inverse languages:

1. Core participants of transitive predicates are ranked on a hierarchy of salience, topicality or animacy.
2. Only transitive predicates can participate in the direct–inverse alternation.
3. A morphosyntactic device should be used to signal whether the most salient participant is notional subject or notional object.
4. Direct–inverse alternation does not entail detransitivization.

Some languages that comply with Klaiman's definition of an inverse language are Maasai, Carib, Wastek, Chukchi, the Algonquian languages and some Athabaskan languages like Koyukon and Navajo, Mapudungun and Movima (language isolates), rGyalrong (Sino-Tibetan), Kopar (Sepik), and some Mixe–Zoquean languages. On the other hand, the Mixean language Oluteco has been reported to have an inverse system which does not conform to the second rule, as certain intransitive verbs and passives of ditransitives also can take inverse morphology.

Inverse morphology in Ojibwe

In Ojibwe, an Algonquian language of North America, the person hierarchy is second person > first person > third person proximate > third person obviative. Since the morphology of Ojibwe has no case distinctions (an Ojibwe nominal phrase does not change when its relations to the other sentence constituents change), the only way to distinguish subject from object in a transitive verb with two participants is through direct–inverse suffixes. A direct suffix indicates that the action is performed by someone higher on the person hierarchy on someone lower on the person hierarchy:

obizindawaan

o-

3-

bizindaw

listen.to

-aa

-DIRECT

-n

-3OBVIATIVE

"He listens to the other one"

An inverse suffix indicates that the action is performed by someone lower on the person hierarchy on someone higher on the person hierarchy (such as by the speaker on the addressee or an obviative third person on a proximate):

obizindaagoon

o-

3-

bizindaw

listen.to

-igoo

-INVERSE

-n

-3OBVIATIVE

"The other one listens to him"

As can be seen, the only difference between these two verbs is the direct–inverse opposition, rather than case markers (or word order, when distinct nominals are used). An inverse verb is not equivalent to a passive verb. There is a separate passivity marker, denoted in literature as "indefinite person (X)", ranked in topicality hierarchy below first and second persons, but higher than animate and inanimate third persons:

bizindawaa

X-

bizindaw

listen.to

-aa

-DIRECT

"He is listened to"

Semantic and pragmatic inverse in Sahaptin

Sahaptin, an Amerindian language of the northwestern United States, has an inverse marked by the verbal prefix pá-. It indicates transitive action from the second to the first person when both arguments are SAPs. That can be called the semantic inverse.

"I see you"

"you see me"

Sahaptin pá- does not occur with transitive action between SAPs and the third person, but it does occur between third-person participants. The contrast can be elicited with multiple clause examples such as given below. In the inverse the semantic patient is coreferential with the subject in the preceding clause. That can be called a pragmatic inverse.
