InGrammar and Discourse Principles, Susumu Kuno and Ken-ichi Takami critically examine recent work in the Government and Binding framework developed by Chomsky, Rizzi, Lasnik and Saito, Huang, Aoun, and others. They demonstrate that this work encounters a variety of empirical and theoretical difficulties when confronted by an expanded range of data. Alternatively, the authors offer independently motivated functional explanations that account for these data and that do not require postulation of concepts like "L-marking" and "blocking category." Kuno and Takami begin by looking at extraction phenomena, including extraction from complement clauses, the overt subject requirement, and subjacency, and provide functional accounts that improve on theBarriersanalysis. Next, they discuss multiplewhquestions in English and Japanese, with special reference towhyandnaze. The authors also examine and ultimately reject the major arguments in support of Larson's "light predicate raising" analysis. Finally, Kuno and Takami discuss coreferentiality of picture noun reflexives and the relation of quantifier scope interpretations, particularly those in sentences involving psychological verbs such asbother,worry, andplease. In this subtly argued book, the authors raise questions of critical importance for theoretical linguists of all persuasions.Kuno, Susumu is the author of 'Grammar and Discourse Principles Functional Syntax and Gb Theory' with ISBN 9780226462042 and ISBN 0226462048.
