Filler–gap dependencies and the remnant–correlate dependency in backward sprouting: Sensitivity to distance and islands

Abstract

The relationship between the wh-remnant and the null correlate in the type of ellipsis known as backward sprouting is superficially almost identical to the relation between a wh-filler and a gap in a wh-question. In both cases, there is a dependency between the wh-phrase and a later null element. We conduct a sentence acceptability experiment to test whether the remnant–correlate dependency in backward sprouting exhibits two well-known properties of a filler–gap dependency in wh-questions: sensitivity to clause boundaries (distance) and sensitivity to islands. The results show that both dependency types are sensitive to clause boundaries, although the effect is larger in the case of filler–gap dependencies, but that only filler–gap dependencies are sensitive to islands. These results present a challenge to analyses of sprouting in which the ellipsis site contains a full representation of the structure of the antecedent clause, since such analyses predict island-sensitivity for remnant–correlate dependencies. The results also suggest that island-sensitivity cannot be reduced to simple processing demands without regard to the syntactic representation of the dependency, since such a view would predict greater similarity between filler–gap dependencies and remnant–correlate dependencies than is found.
