Case and referential properties

In this paper we discuss a number of languages with a multidimensional Differential Object Marking (DOM) system. In such languages overt object marking is determined by more than one argument feature such as animacy or definiteness. We will show that such argument features can be related to case marking in different ways. On the one hand, they can trigger the occurrence of overt marking, on the other they can be the result of it. We will demonstrate that different languages may prioritize the different argument features in different ways. These cross-linguistic patterns call for a more flexible approach to DOM than hitherto developed. We develop a sign-based declarative model that does not rely on hierarchies but instead accounts for language-specific patterns and cross-linguistic variation on the basis of feature structures.
