Modification and underspecification : a free variable account of locative modifiers

Abstract

The present paper offers evidence that there are two variants of adverbial modification that differ with respect to the way in which a modifier is linked to the verb's eventuality argument. So-called external modifiers relate to the full eventuality, whereas internal modifiers relate to some integral part of it. The choice between external and internal modification is shown to be dependent on the modifier's syntactic base position. External modifiers are base-generated at the VP periphery, whereas internal modifiers are base generated at the V periphery. These observations are accounted for by a refined version of the standard Davidsonian approach to adverbial modification according to which modification is mediated by a free variable. In the case of external modification, the grammar takes responsibility for identifying the free variable with the verb's eventuality argument, whereas in the case of internal modification, a value for the free variable is determined by the conceptual system on the basis of contextually salient world knowledge.
