A “Maximal Exclusion” Approach to Structural Underspecification in Dynamic Syntax

Abstract

‘Case’ and ‘grammatical relations’ are central to syntactic theory, but rigorous treatments of these concepts in surface-oriented grammars such as Dynamic Syntax are pending. In this respect, Japanese is worthy of mention; in this language, the nominative case particle ga, which typically marks a subject, may mark an object in certain syntactic contexts, and more than one instance of ga may be present within a single clause. These patterns cannot be captured if we simply assume that ga marks a subject. In the present article, we aim to advance formal aspects of the framework, especially the mechanism of ‘structural underspecification,’ by proposing that the parse of a case particle maximally excludes potential landing sites of an unfixed node at the time of parsing the case particle, delaying the resolution of the unfixed node until a subsequent stage of structure building. This maximal exclusion approach to structural underspecification accounts for a range of case marking patterns and their connections with grammatical relations.
