Insofar as purpose clauses appear to be adverbial, they frequently
occupy a relatively low place on the scale of important things for
syntactic theory to address itself to. In this book I assume the
theoretical framework that has come to be known as 'Government-Binding'
theory (GB), initiated in Chomsky (1981). The general fonn of the
analyis of purpose clauses in GB dates roughly from Chomsky (1977).
where several kinds of constructions akin to purpose clauses are
identified. Within GB. this analysis is so widely accepted that it
deserves to be considered the standard theory. This book, then. is about
a few syntactically peripheral ell ments that have enjoyed a relatively
long-lived. virtually universally accepted. theoretical treatment What
is perhaps an obvious question arises in this context. Why write a GB
book about purpose clauses? This book. I hope, will supply an
interesting answer. Simply put. purpose clause: , and related
constructions, have various properties that are not accounted for in the
standard theory. In this book I propose an alternative analysis of
purpose clauses, an analysis from which. I think. more of their
properties follow more naturally.
