Ergative–absolutive alignment

Pattern relating to the subject and object of verbs

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. Examples include Basque, Georgian, Mayan, Tibetan, and certain Indo-European languages. It has also been attributed to the Semitic modern Aramaic languages. Ergative languages are classified into two groups: those that are morphologically ergative but syntactically behave as accusative 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. 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.
