This edited book provides a comprehensive survey of the modern state of the art in forensic linguistics. Part I of the book focuses on the role of the linguist as an expert witness in common law and civil law jurisdictions, the relation of expert witnesses and lawyers, ethics standards, and courtroom interaction. Part II deals with some of the major areas of expertise of forensic linguistics as the scientific study of language as evidence, namely authorship identification, speaker identification, text authentication, deception and lie detection, plagiarism detection, and cyber language crimes. This book is intended to be used as a reference for academics, students and practitioners of Linguistics, Forensic Linguistics, Law, Criminology, and Forensic Psychology, among other disciplines.

Overview of the interface of language and the law, illustrated with authentic data and contemporary case studies. Topics include collection of evidence, discourse, courtroom interaction, legal language, comprehension and forensic phonetics.

With the permission of a North Carolina court, more than 150 hours of courtroom speech were recorded for this study. These tapes provided a rich archive for a variety of different types of inquiry, including the ethnography of courtroom speech and social psychological experiments focused on effects of different modes of presenting information in courts of law. Four sets of linguistic variables and related experimental studies have constituted a major portion of the research: (1) "powerful" versus "powerless" speech; (2) hypercorrect versus formal speech; (3) narrative versus fragmented testimony, and (4) simultaneous speech by witnesses and lawyers. All four sets of studies focus on the central question of importance of form over content of testimony.

An Introduction to Forensic Linguistics: Language in Evidence has established itself as the essential textbook written by leading authorities in this expanding field. The second edition of this bestselling textbook begins with a new introduction and continues in two parts. Part One deals with the language of the legal process, and begins with a substantial new chapter exploring key theoretical and methodological approaches. In four updated chapters it goes on to cover the language of the law, initial calls to the emergency services, police interviewing, and courtroom discourse. Part Two looks at language as evidence, with substantially revised and updated chapters on the following key topics: the forensic linguist forensic phonetics authorship attribution the linguistic investigation of plagiarism the linguist as expert witness. The authors combine an array of perspectives on forensic linguistics, using knowledge and experience gained in legal settings – Coulthard in his work as an expert witness for cases such as the Birmingham Six and the Derek Bentley appeal, and Johnson as a former police officer. Research tasks, further reading, web links, and a new conclusion ensure that this remains the core textbook for courses in forensic linguistics and language and the law. A glossary of key terms is also available at https://www.routledge.com/products/9781138641716 and on the Routledge Language and Communication Portal.

What counts as evidence in linguistics? This question is addressed by the contributions to the present volume (originally published as a Special Issue of Studies in Language 28:3 (2004). Focusing on the innateness debate, what is illustrated is how formal and functional approaches to linguistics have different perspectives on linguistic evidence. While special emphasis is paid to the status of typological evidence and universals for the construction of Universal Grammar (UG), this volume also highlights more general issues such as the roles of (non)-standard language and historical evidence. To address the overall topic, the following three guiding questions are raised: What type of evidence can be used for innateness claims (or UG)?; What is the content of such innate features (or UG)?; and, How can UG be used as a theory guiding empirical research? A combination of articles and peer commentaries yields a lively discussion between leading representatives of formal and functional approaches.

Review text: "A volume which has indeed presented a rich picture of the role of linguistic evidence in the contemporary, especially generative, study of language."Gerard Steen in: Functions of Language 1/2007.

Input and Evidence: the raw material of second language acquisition is an empirical and theoretical treatment of one of the essential components of SLA: the input to language learning mechanisms. It reviews and adds to the empirical studies showing that negative evidence (correction, feedback, repetitions, reformulations) play a role in language acquisition in addition to that played by ordinary conversation. At the same time, it embeds discussion of input within a framework which includes a serious treatment of language processing, including the problem of modularity and the question of how semantic representations can influence grammatical ones. It lays the foundation for the development of a truly explanatory theory of SLA in the form of the Autonomous Induction Theory which combines a model of induction with an interpretation of Universal Grammar, thereby permitting, for the the first time, a coherent approach to the problem of constraining induction in SLA.
