The Morphosyntax of Case and Adpositions

This dissertation addresses the question of the mapping from syntactic structures to morphological cases. Case is a set of variations in the form of the noun or its associated categories (determiners, pronouns, or adjectives) which is sensitive to syntactic context, particularly argument structure, or semantic interpretation, and generally independent of other nominal features such as number and gender. The central question regards the relationship between cases and adpositions in those contexts in which they overlap, and how recognition of this relationship can be integrated into a consistent treatment of cases, one that accounts for the full range of cases in rich paradigms such as those in the Finno-Ugric languages. The analysis is couched in terms of the Principles and Parameters framework (Chomsky 1981, Chomsky 1986, Chomsky 1995), with the mapping between morphology and syntax working along the lines of Distributed Morphology (Halle and Marantz 1993). The working hypothesis is that at least some cases and adpositions are syntactically identical, differing at the post-syntactic morphological level. The main observation that emerges from the following investigation is that several syntactic subdivisions can be made, both amongst cases (variations in the form of the noun), and amongst adpositions (separate words adjacent to the noun), relating them to the categories P, D and Phi (a projection for number and person features). At the same time some cases and some adpositions perform the same functions: the same set of divisions can be made amongst cases as amongst adpositions. From a syntactic perspective, case is an epiphenomenon, relating to several separate nominal categories. In the morphology, case becomes identifiable as differing from adpositions in many languages, cases forming part of another word and adpositions standing as separate words, as idenitified on language-specific diagnostics for wordhood.
