摘要：Following Romero (2003), this paper develops a unified analysis of two types of N(oun) P(hrase)s: concealed question NPs with know and NP subjects of specificational sentences with be. It is argued that both epistemic know and specificational be are intensional verbs requiring an intensional semantic argument. It is further argued that this semantic argument is, in both cases, propositional in nature. Crosslinguistic data on pronominalization, coordination and matching effects in free relatives are provided in support of these conclusions.
