This new edition has been extensively updated throughout. Major structural changes include new chapters on Functional Heads and Head Movement and on Relativized Minimality. Discussions of a number of topics either absent from or only briefly addressed in the first edition have been integrated or expanded, for example, the structure of small clauses, chain formation, and reconstruction, multiple movement, wh -absorption, full interpretation, and expletive replacement. The copious exercises have been revised to increase potential for creativity and flexibility to approach. New exercises highlight further controversial issues.
