This book collects the papers presented at the Sixteenth West Coast Conference on Formal Linguistics, held at the University of Washington Feb. 28-Mar 2, 1997. Included are more than thirty contributions representing the most recent original research from an international group of generative linguists. These papers cover topics of current theoretical interest in many areas of formal linguistics: phonology, syntax, semantics, and the phonology-syntax and syntax-semantics interfaces. Among them are a number of papers from panel sessions on the specific topics of Tense and Aspect, Superiority, Anaphora, and Optimality Syntax.
