The thesis concerns the syntax and semantics of Ossetic correlatives. First, I describe the functions of correlatives in detail. This construction is the main type of subordination in Ossetic and its frequency by far exceeds that of other subordinate clause types. Second, I describe the main syntactic properties of correlatives and their position in the clause structure of Ossetic. I show that correlatives cannot be adequately described in either the movement-based account (e.g. Bhatt’s analysis of Hindi) or the base-generation account (e.g. Lipták’s treatment of Hungarian). Instead I propose that either structure can be realized depending on syntactic context (cf. Cable’s analysis of Tibetan). Third, I analyze the semantics of correlatives. I show that the properties of this construction suggest an analysis in terms of obligatory anaphoric coreference between the relative DP (DPrel) and the matrix correlate (DPmat). The syntactic and semantic analyses are formalized in Lexical Functional Grammar and Discourse Representation Theory. I also provide a short areal overview of correlatives; a hypothesis of West Caucasian influence is proposed.
