Abstract

Specificational sentences show Connectivity Effects (Akmajian 1970, Higgins 1979, Halvorsen 1978, Jacobson 1994, among others). For example, an NP like no man embedded in a relative clause in general cannot bind a pronoun outside the relative clause, as illustrated in (3a); but in specificational copular sentences this binding is possible, as in (3b). This effect is called Variable Binding Connectivity. Similarly, the NP a unicorn cannot be interpreted de dicto with respect to the embedded verb look for in (4a); but a de dicto reading is possible in the specificational sentence (4b) (Opacity Connectivity). Connectivity will be used in this paper as a diagnosis for specificational sentences
