Romanian tough-constructions and multi-headed constituents
I propose an account for the absence of agreement on <i>tough-</i>words<i> </i>in Romanian <i>tough-</i> constructions (TCs). I argue that absence of agreement cannot be explained by an A-bar movement derivation, because Romanian TCs involve A-movement, the non-finite complement having passive properties. I also argue against an adverb analysis of Romanian <i>tough-</i>words and against a subject analysis of the clausal argument of the <i>tough-</i>word. I propose a novel analysis, which is supported by West Germanic data: non-agreeing TCs are multi-headed constituents, in which the adjective is the internal head, selecting the supine CP, and the supine C is the external head. Since the adjective is not the external head, it cannot take part in agreement relations involving the [Adjective+Supine] constituent. I provide a technical implementation of the notion of multi-headed constituents which relies on Citko’s (2008) flexible label projection: in this case, it is the label of the complement that projects (an instance of Project-Goal). Finally, I discuss the correlation between the availability of multi-headed TCs and the morphological (in)distinctness between adjectives and adverbs.
