This book presents the most complete exposition of the theory of head-driven phrase structure grammar (HPSG), introduced in the authors' "Information-Based Syntax and Semantics." HPSG provides an integration of key ideas from the various disciplines of cognitive science, drawing on results from diverse approaches to syntactic theory, situation semantics, data type theory, and knowledge representation. The result is a conception of grammar as a set of declarative and order-independent constraints, a conception well suited to modelling human language processing.

This book offers a long-awaited unified and precise treatise on construction-based grammar. The approach to grammar presented here is the union of Berkeley Construction Grammar, as represented by the early work of Charles J. Fillmore and Paul Kay, with construction HPSG as pioneered by Ivan Sag, Carl Pollard, and others. The presentation of this theory in a detailed chapter by Sag presents the full outlines of a new approach to grammar. It reflects the confluence of two separate, although converging, traditions, and constitutes a novel synthesis.
