In German, complex wh-interrogatives can optionally be formed by inserting the 3rd person neuter w h-pronoun was in the matrix [Spec, CP] position instead of long-distance wh-raising. It is generally assumed that “expletive” was serves as a placeholder for a contentful wh-expression lower down in the sentence that substitutes for it at the level of semantic interpretation. It can be shown, however, that the putative wh-expletive was in German is actually a CP-proform basegenerated in matrix object position, and that it is not subject to expletive replacement at LF. As an alternative to previous accounts, I propose a complex predicate analysis of the German was … w construction according to which was is a [thetas]-marked object pronoun capable of licensing a predicative CP in V-complement position. This analysis is consistent with Rothstein's (1995) claim that true object expletives do not exist.*
