This book presents an innovative theory of syntactic categories and the lexical classes they define.This book presents an innovative theory of syntactic categories and the lexical classes they define. It revives the traditional idea that these are to be distinguished notionally (semantically). The author proposes a notation based on semantic features which accounts for the syntactic behaviour of classes. The book also presents a case for considering this classification SH again in rather traditional vein SH to be basic to determining the syntactic structure of sentences.This book presents an innovative theory of syntactic categories and the lexical classes they define.
