WH-CLAUSES Haj Ross Department of Linguistics and Technical Communication University of North Texas haj@unt.edu / http://www-personal.umich.edu/~jlawler/hajpapers.html International Conference on Sentence Types Goethe Universität, Frankfurt, Germany Ten Years After June 27, 2009 I. Introduction This paper will seek to demonstrate the existence and distribution of two different types of wh-clauses. I will distinguish between conjunctive wh-clauses (CWHs) and disjunctive wh-clauses (DWHs). In general, it is the latter type of wh- clause which been the focus of most grammatical research which I am aware of, probably because of the fundamental importance of sequences of information- seeking questions and their answers in the worlds grammars, and because of the fact that it is always DWHs which occur in such pairs. The distinction between the two types has a semantic basis: in CWHs, the speaker (or someone in the sentence) knows (or is presupposed to know) the answerto the question: a CWH is a kind of factive clause. In DWHs, by contrast, there is a presupposition that this knowledge is not available (to some relevant person). (1) Conjunctive wh-clauses a. Who Sandor photographed b. Where he developed the film c. What they shot at him with is fantastic to the kids. d. How much he was paid for the negatives e. Why he wants to write it all up (2) Disjunctive wh-clauses a. Who Sandor photographed b.
