Person Marking Alignment refers to how person agreement markers on the verb correspond to the types of verbal arguments, such as the subject of transitive clauses, subject of intransitive clauses, and object of transitive clauses. <br><br>A 'yes' value indicate that the language has an 'hierarchical' system. That is, the type of agreement marker depends on some kind of ontological hierarchy, such as 'Person' (Siewierska 2008). <br><br>  For example, Plains Cree exhibits a Person Hierarchy of 2 > 1 > 3. If there is a 2 person argument, no matter whether the subject or the object is 2 person, it will be the prefixal agreement marker. A 3 person or 1 person marker will be the suffixal agreement marker, as in <i><b>ki</b>-wapam-i-<b>n</b></i> '2.A-see-DIR-1.P' for 'You see me' and <i><b>ki</b>-wapam-iti-<b>n</b></i> '2.P-see-INV-1.P' for 'I see you.' In this example, as in other languages, when the Patient outranks the Agent, an 'Inverse' marker <i>-iti</i> is used. Otherwise, the direct marker <i>-i</i> is used (Siewierska 2008). <br><br><b>Note:</b> Languages which do not exhibit subject and object agreement on the verb will be marked <b>N/A</b> for this value. <br><br><b>Glossing Conventions:</b> Direct markers will be glossed DIR. Inverse markers will be glossed INV. <br><br><b>Reference</b><br>Siewierska, Anna. 2008. Alignment of Verbal Person Marking. In Haspelmath et al. (2008), chapter 100.
