This series offers a wide forum for work on contact linguistics, using an integrated approach to both diachronic and synchronic manifestations of contact, ranging from social and individual aspects to structural-typological issues. Topics covered by the series include child and adult bilingualism and multilingualism, contact languages, borrowing and contact-induced typological change, code switching in conversation, societal multilingualism, bilingual language processing, and various other topics related to language contact. The series does not have a fixed theoretical orientation, and includes contributions from a variety of approaches.

In John McWhorter’s Defining Creole anthology of 2005, his collected articles conveyed the following theme: His hypothesis that creole languages are definable not just in the sociohistorical sense, but in the grammatical sense. His publications since the 1990s have argued that all languages of the world that lack a certain three traits together are creoles (i.e. born as pidgins a few hundred years ago and fleshed out into real languages). He also argued that in light of their pidgin birth, such languages are less grammatically complex than others, as the result of their recent birth as pidgins. These two claims have been highly controversial among creolists as well as other linguists. In this volume, Linguistic Simplicity and Complexity, McWhorter gathers articles he has written since then, in the wake of responses from a wide range of creolists and linguists. These articles represent a considerable divergence in direction from his earlier work.

Language complexity has recently attracted considerable attention from linguists of many different persuasions. This volume – a thematic selection of papers from the conference Approaches to Complexity in Language, held in Helsinki, August 2005 – is the first collection of articles devoted to the topic. The sixteen chapters of the volume approach the notion of language complexity from a variety of perspectives. The papers are divided into three thematic sections that reflect the central themes of the book: Typology and theory, Contact and change, Creoles and pidgins. The book is mainly intended for typologists, historical linguists, contact linguists and creolists, as well as all linguists interested in language complexity in general. As the first collective volume on a very topical theme, the book is expected to be of lasting interest to the linguistic community.

This book presents a challenge to the widely-held assumption that human languages are both similar and constant in their degree of complexity. For a hundred years or more the universal equality of languages has been a tenet of faith among most anthropologists and linguists. It has been frequently advanced as a corrective to the idea that some languages are at a later stage of evolution than others. It also appears to be an inevitable outcome of one of the central axioms of generative linguistic theory: that the mental architecture of language is fixed and is thus identical in all languages and that whereas genes evolve languages do not. Language Complexity as an Evolving Variable reopens the debate. Geoffrey Sampson's introductory chapter re-examines and clarifies the notion and theoretical importance of complexity in language, linguistics, cognitive science, and evolution. Eighteen distinguished scholars from all over the world then look at evidence gleaned from their own research in order to reconsider whether languages do or do not exhibit the same degrees and kinds of complexity. They examine data from a wide range of times and places. They consider the links between linguistic structure and social complexity and relate their findings to the causes and processes of language change. Their arguments are frequently controversial and provocative; their conclusions add up to an important challenge to conventional ideas about the nature of language. The authors write readably and accessibly with no recourse to unnecessary jargon. This fascinating book will appeal to all those interested in the interrelations between human nature, culture, and language.

Foreigners often say that English language is "easy." A language like Spanish is challenging in its variety of verb endings (the verb speak is conjugated hablo, hablas, hablamos), and gender for nouns, whereas English is more straight forward (I speak, you speak, we speak). But linguists generally swat down claims that certain languages are "easier" than others, since it is assumed all languages are complex to the same degree. For example, they will point to English's use of the word "do" -- Do you know French? This usage is counter-intuitive and difficult for non-native speakers. Linguist John McWhorter agrees that all languages are complex, but questions whether or not they are all equally complex. The topic of complexity has become a hot issue in recent years, particularly in creole studies, historical linguistics, and language contact. As McWhorter describes, when languages came into contact over the years (when French speakers ruled the English for a few centuries, or the vikings invaded England), a large number of speakers are forced to learn a new language quickly, and this came up with a simplified version, a pidgin. When this ultimately turns into a "real" language, a creole, the result is still simpler and less complex than a "non-interrupted" language that has been around for a long time. McWhorter makes the case that this kind of simplification happens in degrees, and criticizes linguists who are reluctant to say that, for example, English is simply simpler than Spanish for socio-historical reasons. He analyzes how various languages that seem simple but are not creoles, actually are simpler than they would be if they had not been broken down by large numbers of adult learners. In addition to English, he looks at Mandarin Chinese, Persian, Malay, and some Arabic varieties. His work will interest not just experts in creole studies and historical linguistics, but the wider community interested in language complexity.

This volume is both a state-of-the-art display of current thinking on second language development as a complex system. It is also a tribute to Diane Larsen-Freeman for her decades of intellectual leadership in the academic disciplines of applied linguistics and second language acquisition. The chapters therein range from theoretical expositions to methodological analyses, pedagogical proposals, and conceptual frameworks for future research. In a balanced and in-depth manner, the authors provide a comprehensive and interdisciplinary understanding of second language development, with a wealth of insights that promise to break the status-quo of current research and take it to exciting new territory. The book will appeal to both seasoned and novice researchers in applied linguistics, second language acquisition, bilingualism, cognitive psychology, and education, as well as to practitioners in second or foreign language teaching of any language.
