This chapter analyzes the linear order of inflectional suffixes in the Kiranti language Athpare. It is argued that the order of those suffixes reflects a language-specific hierarchy of morphosyntactic feature classes. The analysis is couched in Optimality Theory and based on ALIGNMENT constraints and a markedness constraint that demands an unambiguous marking of the agent argument. This demand refers to the well-known finding that case-marking and (fixed) order of elements interact in a crucial way. Some closely related Eastern Kiranti languages show a slightly different strategy to mark agent arguments prominently and easily fall out under a slightly modified ranking of the same constraints. From a typological point of view, this study of affix ordering is interesting since the Eastern Kiranti languages do not obey the typological tendency of ordering between person and number agreement following the hierarchy Person >> Number.
