"This book explores a wide variety of theoretically central issues in the framework of Head-Driven Phrase Structure Grammar (HPSG), one of the two major frameworks used in natural language analysis. The editors provide a concise overview of HPSG for those less familiar with it, and the papers in the book, though intended for specialists, are thus for the most part accessible to advanced undergraduate students with only a modest amount of extra background."--BOOK JACKET.
