Abstract
After making clear that the infinitival indirect question has a number of peculiar properties, this article argues that the Government-Binding (GB) approach, as advocated in Chomsky 1981, is not sufficient to properly deal with this construction. It then presents an alternative analysis within the framework of the‘extension theory’, outlined in Kajita 1977, 1983a, 1983b. It is argued that the infinitival indirect question is generated by the‘derivative processes’. Ample evidence is adduced which justifies the proposed analysis.
