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 knowns as a Nominative-Accusative system on pronouns (though it may not on full NPs), where the subject of transitive clauses is formally the same as the subject of intransitive clauses, but the object of transitive clauses is different. <br><br>An example is Standard English, where a subject of transitive/intransitive clauses is normally nominative, as in <i><b>He</b> bit me</i> or <i><b>He</b> fell</i>, but the object is in the accusative case, as in <i>They bit <b>him</b></i>.<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.
