Case markers often distinguish between the various arguments of a predicate, such as the Agent and Patient (Comrie 2008). Three basic types of arguments are generally distinguished: the subject of a transitive clause, the object of a transitive clause, and the subject of an intransitive clause. <br><br>A 'yes' value indicates that the language has what is known as a Ergative-Absolutive system on Pronouns (though not necessarily on full NPs), where the subject of intransitive clauses is formally the same as the object of transitive clauses, but the subject of transitive clauses is different. The unique case for the subject of transitive clauses is known as <b>Ergative</b> case, while the others are known as <b>Absolutive</b>. <br><br>[NEED EXAMPLE]<br><br><b>Note:</b> Languages have no overt case marking on pronouns will be marked <b>N/A</b> for this property. <br><br><b>Reference</b><br>Comrie, Bernard. 2008.
