 Case markers often distinguish between the various arguments of a predicate, such as the Agent and Patient. 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 for this property indicates that the language uses case markers to distinguish between inactive and active arguments on <b>Pronouns</b> (regardless of whether this holds for full NPs as well). <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>Glossing Convention:</b> The 'active' case marker will be glossed agent <b>AGT</b>, and the inactive marker will be glossed patient <b>PAT</b>.<br><br><b>Reference</b><br>Comrie, Bernard. 2008.
