Biolinguistics involves the study of language from a broad perspective that embraces natural sciences, helping us better to understand the fundamentals of the faculty of language. This Handbook offers the most comprehensive state-of-the-field survey of the subject available. A team of prominent scholars working in a variety of disciplines is brought together to examine language development, language evolution and neuroscience, as well as providing overviews of the conceptual landscape of the field. The Handbook includes work at the forefront of contemporary research devoted to the evidence for a language instinct, the critical period hypothesis, grammatical maturation, bilingualism, the relation between mind and brain and the role of natural selection in language evolution. It will be welcomed by graduate students and researchers in a wide range of disciplines, including linguistics, evolutionary biology and cognitive science.

The most comprehensive state-of-the-field survey of biolinguistics available.

It is generally agreed that about 7,000 languages are spoken across the world today and at least half may no longer be spoken by the end of this century. This state-of-the-art Handbook examines the reasons behind this dramatic loss of linguistic diversity, why it matters, and what can be done to document and support endangered languages. The volume is relevant not only to researchers in language endangerment, language shift and language death, but to anyone interested in the languages and cultures of the world. It is accessible both to specialists and non-specialists: researchers will find cutting-edge contributions from acknowledged experts in their fields, while students, activists and other interested readers will find a wealth of readable yet thorough and up-to-date information.

Linguistic typology identifies both how languages vary and what they all have in common. This Handbook provides a state-of-the art survey of the aims and methods of linguistic typology, and the conclusions we can draw from them. Part I covers phonological typology, morphological typology, sociolinguistic typology and the relationships between typology, historical linguistics and grammaticalization. It also addresses typological features of mixed languages, creole languages, sign languages and secret languages. Part II features contributions on the typology of morphological processes, noun categorization devices, negation, frustrative modality, logophoricity, switch reference and motion events. Finally, Part III focuses on typological profiles of the mainland South Asia area, Australia, Quechuan and Aymaran, Eskimo-Aleut, Iroquoian, the Kampa subgroup of Arawak, Omotic, Semitic, Dravidian, the Oceanic subgroup of Austronesian and the Awuyu-Ndumut family (in West Papua). Uniting the expertise of a stellar selection of scholars, this Handbook highlights linguistic typology as a major discipline within the field of linguistics.

The most comprehensive overview available, this Handbook is an essential guide to sociolinguistics today. Reflecting the breadth of research in the field, it surveys a range of topics and approaches in the study of language variation and use in society. As well as linguistic perspectives, the handbook includes insights from anthropology, social psychology, the study of discourse and power, conversation analysis, theories of style and styling, language contact and applied sociolinguistics. Language practices seem to have reached new levels since the communications revolution of the late twentieth century. At the same time face-to-face communication is still the main force of language identity, even if social and peer networks of the traditional face-to-face nature are facing stiff competition of the Facebook-to-Facebook sort. The most authoritative guide to the state of the field, this handbook shows that sociolinguistics provides us with the best tools for understanding our unfolding evolution as social beings.

How are two or more languages learned and contained in the same mind or the same community? This handbook presents an up-to-date view of the concept of multi-competence, exploring the research questions it has generated and the methods that have been used to investigate it. The book brings together psychologists, sociolinguists, Second Language Acquisition (SLA) researchers, and language teachers from across the world to look at how multi-competence relates to their own areas of study. This comprehensive, state-of-the-art exploration of multi-competence research and ideas offers a powerful critique of the values and methods of classical SLA research, and an exciting preview of the future implications of multi-competence for research and thinking about language. It is an essential reference for all those concerned with language learning, language use and language teaching.

Language contact - the linguistic and social outcomes of two or more languages coming into contact with each other - starts with the emergence of multilingual populations. Multilingualism involving plurilingualism can have various consequences beyond borrowing, interference, and code-mixing and -switching, including the emergence of lingua francas and new language varieties, as well as language endangerment and loss. Bringing together contributions from an international team of scholars, this Handbook - the second in a two-volume set - engages the reader with the manifold aspects of multilingualism and provides state-of-the-art research on the impact of population structure on language contact. It begins with an introduction that presents the history of the scholarship on the subject matter. The chapters then cover various processes and theoretical issues associated with multilingualism embedded in specific population structures worldwide as well as their outcomes. It is essential reading for anybody interested in how people behave linguistically in multilingual or multilectal settings.
