This book explores a wide variety of theoretically central issues in the framework of Head-Driven Phrase Structure Grammar (HPSG), a major theory of syntactic representation, particularly in the domain of natural language computation. HPSG is a strongly lexicon-driven theory, like several others on the scene, but unlike the others it also relies heavily on an explicit assignment of linguistic objects to membership in a hierarchically organised network of types, where constraints associated with any given type are inherited by all of its subtypes. This theoretical architecture allows HPSG considerable flexibility within the confines of a highly restrictive, mathematically explicit formalism, requiring no derivational machinery and invoking only a single level of syntactic representation. The separate chapters consider a variety of problematic phenomena in German, Japanese and English and suggest important extensions of, and revisions to, the picture of HPSG.

In syntactic analysis, as in linguistics generally, the skills required to first identify, and then make sense of, complex patterns in linguistic data involve a certain specific kind of reasoning, where various alternatives are entertained and modified in light of progressively broader empirical coverage. Rather than focus on transmitting the details of complex theoretical superstructures, this textbook takes a practical, analytical approach, starting from a small set of powerful analytic tools, applied first to simple phenomena and then to the passive, complement and raising/control constructions. The analytic tools are then applied to unbounded dependencies, via detailed argumentation. What emerges is that syntactic structure, and intricate networks of dependencies linking different parts of those structures, are straightforward projections of lexical valence, in tandem with very general rules regulating the sharing of feature values. Featuring integrated exercises and problems throughout each chapter, this book equips students with the analytical tools for recognizing and assessing linguistic patterns.
