Composing CPs: Evidence from disjunction and conjunction

Abstract
In this paper we compare CP disjunction to TP disjunction and CP conjunction to TP conjunction, and conclude that CPs and TPs do not have identical meanings (cf. similar observations reported in Szabolcsi 1997, 2016; Bjorkman 2013). We argue that this result is incompatible with the view that the CP layer of embedded clauses is semantically vacuous. We propose that the differences between CPs and TPs can be explained under a particular implementation of Kratzer's approach to the semantics of clausal embedding (Kratzer 2006, 2016; Bogal-Allbritten 2016, 2017; Moulton 2009, 2015; Elliott 2017), according to which CPs denote predicates of events whose content equals the embedded proposition.
