Analysis of language as a combination of both a structural and a lexical component overlooks a third all-encompassing aspect: dynamics. Dynamic Linguistics approaches the description of the complex phenomenon that is human language by focusing on this important but often neglected aspect. This book charts the belated recognition of the importance of dynamic synchrony in twentieth-century linguistics and discusses two other key concepts in some detail: speech community and language structure. Because of their vital role in the development of a dynamic approach to linguistics, the three linguists William Labov, André Martinet and Roman Jakobson are featured, in particular Martinet in whose later writings - neglected in the English-speaking world - the fullest appreciation of the dynamics of language to date are found. A sustained attempt is also made to chronicle precursors, between the nineteenth century and the 1970s, who provided inspiration for these three scholars in the development of a dynamic approach to linguistic description and analysis. The dynamic approach to linguistics is intended to help consolidate functional structuralists, geolinguists, sociolinguists and all other empirically minded linguists within a broader theoretical framework as well as playing a part in reversing the overformalism of the simplistic structuralist framework which has dominated, and continues to dominate, present-day linguistic description.

Dynamic systems theory, a general theory of change and development, offers a new way to study first and second language development and requires a new set of tools for analysis of empirical data. After a brief introduction to the theory, this book, co-authored by several leading scholars in the field, concentrates on tools and techniques recently developed to analyze language data from a dynamic perspective. The chapters deal with the general thoughts and reasoning behind coding data, analyzing variability, discovering interacting variables and modeling. The accompanying How to sections give step-by-step instructions to using macros to speed up the coding, creating a dedicated lexical profile, making min-max graphs, testing for significance in single case studies by running simulations, and modeling. Example files and data sets are available on the accompanying website (http://dx.doi.org/10.1075/lllt.29.website). Although the focus is on second language development, the tools are applicable to a wide range of phenomena in applied linguistics.

This book brings together a collection of articles characterized by two main themes: the contrastive study of parallel phenomena in two or more languages, and an essentially functional approach in which language is regarded, first and foremost, as a rich and complex communication system, inextricably embedded in sociocultural and psychological contexts of use. The majority of the studies reported is empirical in nature, many making use of corpora or other textual materials in the language(s) under investigation. The book begins with an introductory section in which the editors provide surveys of the state of the art in both functional and contrastive linguistics. The other five sections of the volume are devoted to (i) a cognitive perspective on form and function, (ii) information structure, (iii) collocations and formulaic language, (iv) language learning, and (v) discourse and culture.

Open publication The volume deals with previously undescribed morphosyntactic variations and changes appearing in settings involving language contact. Contact-induced changes are defined as dynamic and multiple, involving internal change as well as historical and sociolinguistic factors. A variety of explanations are identified and their relationships are analyzed. Only a multifaceted methodology enables this fine-grained approach to contact-induced change. A range of methodologies are proposed, but the chapters generally have their roots in a typological perspective. The contributors recognize the precautionary principle: for example, they emphasize the difficulty of studying languages that have not been described adequately and for which diachronic data are not extensive or reliable. Three main perspectives on contact-induced language change are presented. The first explores the role of multilingual speakers in contact-induced language change, especially their spontaneous innovations in discourse. The second explores the differences between ordinary contact-induced change and change in endangered languages. The third discusses various aspects of the relationship between contact-induced change and internal change.

This book honours the contribution of Marjolijn Verspoor to the development and implementation of dynamic usage-based (DUB) approaches in second language (L2) research and pedagogy. With chapters written by renowned experts in the field, the book addresses the dynamics of language, language learning and language teaching from a usage-based perspective. The book contains both theory and empirical work: the initial theoretical chapters present cutting-edge thinking in relation to both the scope of DUB theory and its applications, providing conceptual perspectives from cognitive grammar and linguistics, thinking-for-speaking (TFS), and Complex Dynamic Systems Theory (CDST) approaches, united by their shared underpinnings of language as a dynamic system of conventionalized routines. The second half of the volume showcases state-of-the-art methodologies to study dynamic trajectories of language learning, empirical investigations into the above-mentioned theoretical concepts, and innovative classroom implementations of DUB language pedagogy.

In this dissertation we present Helvetia, a novel approach to embed languages into an existing host language by leveraging the underlying representation of the host language used by these tools. We introduce Language Boxes, an approach that offers a simple, modular mechanism to encapsulate (i) compositional changes to the host language, (ii) transformations to address various concerns such as compilation and syntax highlighting, and (iii) scoping rules to control visibility of fine-grained language changes. We describe the design and implementation of Helvetia and Language Boxes, discuss the required infrastructure of a host language enabling language embedding, and validate our approach by case studies that demonstrate different ways to extend or adapt the host language syntax and semantics.

This landmark volume offers a collection of conceptual papers and data-based research studies that investigate the dynamics of language learning motivation from a complex dynamic systems perspective. The chapters seek to answer the question of how we can understand motivation if we perceive it as a continuously changing and evolving entity rather than a fixed learner trait.
