Man-Kun Yoon. 1999. Unselective Binding and Multiple Wh-Fronting Constructions. Studies in Modern Grammar 15, 23-41. The first aim of this paper is to argue that any event in our world necessarily co-occurs with four adverbials such as time, place, manner and reason adverbials which can turn into four different wh-adjuncts; when, where, why and how. This paper further argues that this phenomenon is language universal. Second aim is that unselective binding applies only to wh-NPs, not wh-adjuncts, and hence covert raising is necessary for the checking of wh-adjuncts. Although wh-NPs can be interpreted in situ by unselective binding, case checking of wh-NPs requires covert or overt raising of them. Third aim is that nominative wh-NPs can be checked by C。 and accusative wh-NPs by C^(omax). More elaborate purposes are given below in introduction:
