Book excerpt: First Published in 1997. This book is devoted to an in-depth investigation of some of the properties of Logical Form (LF). The syntactic analyses argued for in this book are couched in terms of Chomsky’s Principles and Parameters approach prior to its most recent version known as “Minimalism” (Chomsky, 1995). However, the model of the syntax-semantics interface advocated in this book remains intact under minimalist assumptions, as the aspects of the syntactic representation known as LF investigated here have remained unaltered in the most recent version of generative syntax.
