Flat structure: a minimalist program for syntax

We explore the possibility of assuming largely flat syntactic structures in Simpler Syntax, suggesting that these are plausible alternatives to conventional hierarchical structures. We consider the implications of flat structure for analyses of various linguistic phenomena in English, including heavy NP shift, extraposition, topicalization and constituent order variation in the VP. We also sketch a general strategy to circumvent some of the problems flat structure is said to cause for semantic interpretation. Our proposals eliminate the need for movement, unpronounced copies and feature-bearing nodes postulated to trigger syntactic operations. We assume the Parallel Architecture and use declarative schemas to establish direct correspondences between phonology on the one hand and syntactic and semantic structures on the other. The resulting picture is one in which narrow syntax can be relatively stable across languages and constructions, largely reflecting the structure of human thought, and the main source of linguistic variation is the linearization of conceptual and syntactic structures. Unlike other minimalist theories that reach a similar conclusion, the theory we propose takes mappings to phonology to be central to the architecture of grammar.
