Cross-referencing of non-subject arguments in Pama-Nyungan languages

ABSTRACT About one third of the Pama-Nyungan languages of Australia employ pronominal cross-referencing, yet systematic typological patterns of non-subject argument registration remain unexamined. We analyze this variation from two perspectives by surveying 22 Pama-Nyungan languages. Firstly, we survey which kinds of case-marked arguments can be cross-referenced by these pronominal systems. From this perspective, we find that a number of nominal expressions marked with so-called ‘local’ cases (e.g. locative, allative, ablative, etc.) can be cross-referenced when instantiating certain argument relations. Secondly, we find striking cross-linguistic predictability in how such relations, which we descriptively group as ‘locational’, are morphologically integrated into the pronominal paradigms. We show that the variation can be captured by two major parameters: firstly, whether locational cross-referencing utilizes the same form as another non-subject series, or whether locational cross-referencing is serviced by a unique series formally built off another non-subject series. In this latter case there is further variation as to which other non-subject series provides the base for the dedicated locational series. These parameters result in six surface pattern types, and we show that each of the patterns is instantiated in languages of the survey.
