The essays collected in this volume, most previously unpublished, address a number of closely interconnected issues raised by the comparative syntax of functional heads within the Principles-and-Parameters approach. The general theory of head movement, the properties of derived structures created by incorporation, and the parameterization involved are the main theoretical foci. One major empirical area which is addressed concerns head movement in configurations involving certain kinds of operator-like elements, for example, the different manifestations of Verb Second phenomena in Wh and other constructions and the syntax of negative heads and specifiers. In addition, properties of functional heads and head movement in nominal and clausal structures and the causative construction are investigated.

In this book, Ian Roberts argues that the essential insight of the principles-and-parameters approach to variation can be maintained - albeit in a somewhat different guise - in the context of the minimalist programme. The book represents a significant new contribution to the formal study of cross-linguistic morphosyntactic variation.

Parameters of linguistic variation were originally conceived, within the chomskyan Principles and Parameters Theory, as UG-determined options that were associated with grammatical principles and had a rich deductive structure. This characterization of parametric differences among languages has changed significantly over the years, especially so with the advent of Minimalism. This book collects a representative sample of current generative research on the status, origin and size of parameters. Often taking diverging views, the papers in the volume address some or all of the main debated topics in parametric syntax: i.e. are parameters provided by UG, or do they constitute emergent properties arising from points of underspecification?; in which component(s) of the language faculty are parameters to be found?; do clustering effects actually hold across languages?; do macroparameters exist alongside microparameters?; are there parameter hierarchies?; which is the origin and role of parameters in the process of language acquisition? The volume is organized into two parts. Part I ("The nature of variation and parameters") brings together studies whose main goal is to discuss general issues related to parameters (or variation more generally). Part II ("Parameters in the analysis of language variation: case studies") includes a number of works that deal with the empirical basis and proper formulation of well-known particular parameters: the Null Subject Parameter, the NP/DP Parameter, the Compounding Parameter, the Wh-Parameter and the Analyticity Parameter.

This volume explores how human languages become what they are, why they differ from one another in certain ways but not in others, and why they change in the ways that they do. Given that language is a universal creation of the human mind, the puzzle is why there are different languages at all: why do we not all speak the same language? Moreover, while there is considerable variation, in some ways grammars do show consistent patterns: why are languages similar in those respects, and why are those particular patterns preferred? Peter Culicover proposes that the solution to these puzzles is a constructional one. Grammars consist of constructions that carry out the function of expressing universal conceptual structure. While there are in principle many different ways of accomplishing this task, languages are under press to reduce constructional complexity. The result is that there is constructional change in the direction of less complexity, and grammatical patterns emerge that more efficiently reflect conceptual universals. The volume is divided into three parts: the first establishes the theoretical foundations; the second explores variation in argument structure, grammatical functions, and A-bar constructions, drawing on data from a variety of languages including English and Plains Cree; and the third examines constructional change, focusing primarily on Germanic. The study ends with observations and speculations on parameter theory, analogy, the origins of typological patterns, and Greenbergian 'universals'.
