From aspect to information structure: Non-aspectual functions of change of state markers in Austronesian and beyond

This paper discusses a phenomenon that has so far received little attention in previous literature: the presence, in several languages from different branches of the Austronesian family, of polyfunctional markers, which combine an aspectual meaning of change of state with information and discourse structuring functions. In this study, based on a comparative analysis of fifty-two Austronesian languages, I show that polyfunctional change of state markers are distributed throughout the entire family, crosscutting the major typological and geographical divide between Western and Eastern Austronesian. I argue that the development of information and discourse structuring functions of change of state markers derives from applying the notions of current relevance and transition to new situation not to eventualities, but to elements of propositions, and I also suggest that this process may be universally valid and could explain the similar development of change of state markers into information and discourse structuring devices attested in non-Austronesian languages.
