The interpretation of external arguments
This chapter examines the syntactic and semantic properties of heads, e.g. Voice, Appl, and little p, that add participants to events. Instead of assuming that such heads exist as distinct primitives in the functional lexicon, it is proposed that there is one such head, which can get different interpretations depending on how it is merged into the structure. The chapter’s approach attributes the relative uniformity of the expression of argument structure to the principles that interpret syntactic structure semantically; thus, syntax is truly autonomous, with the atoms of syntactic representations carrying no inherent semantic values. Once syntactic heads are absolved from the necessity of explicitly carrying certain features relevant to their interpretation, a sparse inventory of functional heads can be developed. The system is applied to a set of constructions that present distinct challenges to theories that demand a kind of transparent reflection of argument structure in underlying syntactic representations.
