The grammatical phenomenon of control subsumes a variety of cases where an understood argument of a complement or adjunct clause is related to an explicit element occurring elsewhere in the sentence. The control phenomenon, though familiar from many languages, and widely discussed, has remained a persistent and controversial topic in grammatical analysis. This volume presents nine new, theoretical studies of control. The authors explore the subject matter across a range of languages and constructions, in several different frameworks, and from a variety of perspectives including syntax, semantics, psycholinguistics and historical linguistics. The articles in this collection offer a stimulating introduction to the spectrum of issues in control theory and their bearing on theoretical linguistics today. The contributors include: Steven Franks, Kenneth Hale, James Higginbotham, Norbert Hornstein, James Huang, Pauline Jacobson, Brian Joseph, Howard Lasnik, Kenneth Wexler, and Edwin Williams.
