Specificational pseudoclefts (SPCs) have been a great challenge for a syntactic theory, because, despite the surface division between the pre- and post-copular elements, the post-copular `pivot' behaves as if it occupied the gap position in the precopular wh-clause. This paper argues that movement-based or deletion-based syntactic approaches and purely semantic approaches have problems in dealing with syntactic properties and connectivity problems of SPCs in English. Observing the parallelism between SPC pivots and short answers to questions, it proposes an HPSG account based on a non-deletion-based QDT (Question-in-disguise theory) approach and on the equative analysis of the specificational copular sentences. The paper shows that SPCs must be handled by an integrated account of the syntactic, semantic, and pragmatic properties of the construction, and argues that the connectivity problems should be approached from such an integrated view.
