Recent developments in the generative tradition have created new interest in matters of argument structure and argument projection, giving prominence to the discussion on the role of lexical entries. Particularly, the more traditional lexicalist view that encodes argument structure information on lexical entries is now challenged by a syntactic view under which all properties of argument structure are taken up by syntactic structure. In the light of these new developments, the contributions in this volume provide detailed empirical investigations of argument structure phenomena in a wide range of languages. The contributions vary in their response to the theoretical questions and address issues that range from the role of specific functional heads and the relation of argument projection with syntactic processes, to the position of argument structure within a broader clausal architecture and the argument structure properties of less studied categories.
