Forensic linguistics has come a long way since the term was first used in Jan Svartvik's publication of The Evans Statement: a Case for Forensic Linguistics in 1968. Since then, a large body of research has contributed to the considerable growth and professionalism of this multi and cross-disciplinary field; practitioners regularly perform casework, resulting in significant contributions to the delivery of justice. The question remains, though, of what is forensic linguistics? It can be seen as an area of applied linguistics in which linguistic knowledge is applied to forensic situations and data (Perkins & Grant, 2013). Linguistics involves the analysis of human communication as written texts or linguistic interaction by describing and explaining the nature of the communication on a number of linguistic levels, using a variety of interpretative tools, theories, and methods. In forensic linguistic casework the analyst takes the linguist's toolbox and applies it to real forensic contexts where texts are often unhelpfully short, in contrast to large collections used in academic research. Advancements in forensic linguistic research reveal language to be incredibly adaptive and complex. With forensic linguistics being a newly emerged science, there are still significant differences in practitioners' analytical approaches to forensic linguistic casework. This book explores in an academic context the current methodologies used in all aspects of linguistic analyses in forensic settings. Using real cases, practitioners discuss relevant knowledge and the methodological choices they made to analyse the material, exploring in-depth the reasons behind their approach demonstrating how their methodology(ies) work with data and specifics from the cases (where possible), and how these led to the conclusions they arrived at. This book showcases the breadth of casework that forensic linguists have been involved with recently, providing a comprehensive overview of how linguistic theory can be applied to the analysis of texts in real forensic contexts. In standard academic literature, methodologies are largely discussed in relation to research of idealised cases which often bear little resemblance to the real world constraints that exists with actual casework. Through the description of methodologies and the reasons behind methodological choices, this book also provides a comprehensive review of current linguistic knowledge and its theoretical application in areas such as authorship analysis and profiling, plagiarism, adversarial translations, product warnings, trademarks, and determination of meaning, as well as presenting examples of current good practice while recognising that this is an evolving field. This book is aimed at students, academics, and professionals interested in language in investigative or forensic contexts and in the interaction of language and the law. It is intended to serve as a platform to encourage further research and to promote discussion within an international academic setting on the reliability and validity of methodologies. It draws on the expertise of forensic linguist practitioners worldwide, and it is linked to the current International Association of Forensic Linguists (IAFL) discussions on best practice and quality assurance to ensure that methodologies are underpinned by a robust evidence base.
