The contributions of this book deal with the issue of language variation. They all share the assumption that within the language faculty the variation space is hierarchically constrained and that minimal changes in the set of property values defining each language give rise to diverse outputs within the same system. Nevertheless, the triggers for language variation can be different and located at various levels of the language faculty. The novelty of the volume lies in exploring different loci of language variation by including wide-ranging empirical perspectives that cover different levels of analysis (syntax, phonology and prosody) and deal with different kinds of data, mostly from Romance and Germanic languages, from dialects, idiolects, language acquisition, language attrition and creolization, analyzed from both diachronic and synchronic perspectives. The volume is divided in three parts. The first part is dedicated to synchronic variation in phonology and syntax; the second part deals with diachronic variation and language change, and the third part investigates the role of contact, attrition and acquisition in giving rise to language change and language variation in bilingual settings. This volume is a useful tool for linguistics of diverse theoretical persuasions working on theoretical and comparative linguistics and to anyone interested in language variation, language change, dialectology, language acquisition and typology.

This book for the first time reconstructs in a single theoretical framework the more important approaches to linguistic variation found in areas as different as historical linguistics, dialectology, sociolinguistics, psycholinguistics, stylistics, contrastive linguistics, language typology, so-called evaluation grammar, and current Chomskyan generative grammar (generally with an emphasis on syntax). The book concentrates on language-internal variation but also analyses typological research and considers the question of how linguistic descriptions may account for variation both within and between languages. The book's first and primary aim is adequate conceptualization in the area of linguistic variation. Its second aim is a practical one: to contribute, from a theoretical point of view, to the vast descriptive effort that is demanded in linguistics in documenting endangered languages. Its third aim is, simply, orientation. Using a non-Labovian notion of linguistic variable, the author distinguishes a holistic and a component approach to linguistic variation. A precise version of the former is developed by formulating a theory of language varieties based on the concept of variety structure of a language; it is then shown how the proposals made by major representatives of the component approach can be integrated into this framework. The theory is extended to interlanguage variation and applied, in particular, to typology. It is further extended to establish the properties of linguistic descriptions that account for variation in a unified way.

Linguistic Variation: Confronting Fact and Theory honors Shana Poplack in bringing together contributions from leading scholars in language variation and change. The book demonstrates how variationist methodology can be applied to the study of linguistic structures and processes. It introduces readers to variation theory, while also providing an overview of current debates on the linguistic, cognitive and sociocultural factors involved in linguistic patterning. With its coverage of a diverse range of language varieties and linguistic problems, this book offers new quantitative analyses of actual language production and processing from both top experts and emerging scholars, and presents students and practitioners with theoretical frameworks to meaningfully engage in accountable research practice.

Why does human language vary from one person, or one group, to another? In what ways does it vary? How do linguists go about studying variation in, say, the sound system or the sentence structure of a particular language? Why is the study of language variation important outside the academic world, in say education, the law, employment or housing? This book provides an overview of these questions, bringing together a team of experts to survey key areas within the study of language variation and language change. Covering both the range of methods used to research variation in language, and the applications of such research to a variety of social contexts, it is essential reading for advanced students and researchers in sociolinguistics, communication, linguistic anthropology and applied linguistics.

The present volume has its origin in the GLOW conference on Universals hosted in Berlin in March 1999. The papers in this volume are concerned both with formal as well as with substantive universals. All the contributions attempt to identify universal properties of the language faculty, as well as the source of cross-linguistic variation. They cover a wide range of empirical phenomena across languages such as locality, deletion, verb classes, XP-split constructions, Quantifier Raising, the EPP, the Person Case Constraint etc. Some of the articles pay particular attention to the organization of the grammar, the type of operations that are effective, the role of features in determining variation, and primitive notions of phrase-structure (c-command, Agree etc.). Others show how structural differences capture semantic and morphological differences within a language and across languages, and how these are the ultimate source of linguistic variation. The book is of primary interest to researchers and students in syntactic theory, comparative syntax, and linguistic variation.

This volume brings together research on panel studies with the aim of providing a coherent empirical and theoretical knowledge-base for examining the impact of maturation and lifespan-specific effects on linguistic malleability in the post-adolescent speaker. Building on the work of Wagner and Buchstaller (2018), the present collection offers a critical examination of the theoretical implications of panel research across a range of geographic regions and time periods. The volume seeks to offer a way forward in the debates circling about the phenomenon of later-life language change, drawing on contributions from a variety of linguistic disciplines to examine critical topics such as the effect of linguistic architecture, the roles of mobility and identity construction, and the impact of frequency effects. Taken together, this edited collection both informs and pushes forward key questions on the nature of lifespan change, making this key reading for students and researchers in cognitive linguistics, historical linguistics, dialectology, and variationist sociolinguistics.
