Recent years have seen a growing interest in grammatical variation, a core explanandum of grammatical theory. The present volume explores questions that are fundamental to this line of research: First, the question of whether variation can always and completely be explained by intra- or extra-linguistic predictors, or whether there is a certain amount of unpredictable – or ‘free’ – grammatical variation. Second, the question of what implications the (in-)existence of free variation would hold for our theoretical models and the empirical study of grammar. The volume provides the first dedicated book-length treatment of this long-standing topic. Following an introductory chapter by the editors, it contains ten case studies on potentially free variation in morphology and syntax drawn from Germanic, Romance, Uralic and Mayan.

The aim of the volume is to bridge the 'cultural gap' between sociolinguistics and theoretical linguistics in the study of variation. The various contributions seek to combine corpus-based and competence-based approaches. They document the plurality

This book provides an overview of current issues in variation and gradience in phonetics, phonology and sociolinguistics. It contributes to the growing interest in gradience and variation in theoretical phonology by combing research on the factors underlying variability and systematic quantitative results with theoretical phonological considerations. Variation is inherent to language, and one of the aims of phonological theory is to describe and explain the mechanisms underlying variation at every level of phonological representation. Variation below the segment concerns articulatory, acoustic and perceptual cues that contribute to the formation of natural classes of sounds. At the segmental level there are grammatical differences in the production and perception of contextual variation of segments and in the syntagmatic constraints on the combination of segments. At the suprasegmental level the mapping of tones to grammatical functions and vice versa is discussed. Further aspects addressed in this book are factors outside of language: Variation that arises as a result of a particular dialect or of belonging to a certain age group, or variation that is the consequence of language change. Gradience and variation have always been a central issue in phonetic and sociolinguistic research. Gradience introduces variation in phonology as well. If a phonetic entity can be pronounced in different ways, depending on the environment, prosodic factors or dialectal influences, this ‘gradience’ may introduce ‘variation’, which we understand as a stable state of grammar.

The Cambridge Handbook of English Corpus Linguistics (CHECL) surveys the breadth of corpus-based linguistic research on English, including chapters on collocations, phraseology, grammatical variation, historical change, and the description of registers and dialects. The most innovative aspects of the CHECL are its emphasis on critical discussion, its explicit evaluation of the state of the art in each sub-discipline, and the inclusion of empirical case studies. While each chapter includes a broad survey of previous research, the primary focus is on a detailed description of the most important corpus-based studies in this area, with discussion of what those studies found, and why they are important. Each chapter also includes a critical discussion of the corpus-based methods employed for research in this area, as well as an explicit summary of new findings and discoveries.

Newmeyer persuasively defends the controversial theory of transformational generative grammar. Grammatical Theory is for every linguist, philosopher, or psychologist who is skeptical of generative grammar and wants to learn more about it. Newmeyer's formidable scholarship raises the level of debate on transformational generative grammar. He stresses the central importance of an autonomous formal grammar, discusses the limitations of "discourse-based" approaches to syntax, cites support for generativist theory in recent research, and clarifies misunderstood concepts associated with generative grammar.

The study of how language varies in social context, and how it can be analyzed and accounted for, are the key goals of sociolinguistics. Until now, however, the actual tools and methods have been largely passed on through 'word of mouth', rather than being formally documented. This is the first comprehensive 'how to' guide to the formal analysis of sociolinguistic variation. It shows step-by-step how the analysis is carried out, leading the reader through every stage of a research project from start to finish. Topics covered include fieldwork, data organization and management, analysis and interpretation, presenting research results, and writing up a paper. Practical and informal, the book contains all the information needed to conduct a fully-fledged sociolinguistic investigation, and includes exercises, checklists, references and insider tips. It is set to become an essential resource for students, researchers and fieldworkers embarking on research projects in sociolinguistics.

Where is the locus of language variation? In the grammar, outside the grammar or somewhere in between? Taking up the debate between system- and usage-based approaches, this volume provides new discussions of fundamental issues of language variation. It includes several highly insightful theoretical contributions as well as innovative empirical studies considering different types of data, the role of priming in language change and rare phenomena.
