The 2010 publication The Routledge Handbook of Forensic Linguistics states, in its introduction: “Forensic Linguistics is the study of language and the law, covering topics from legal language and courtroom discourse to plagiarism. It also concerns the applied (forensic) linguist who is involved in providing evidence, as an expert, for the defence and prosecution, in areas as diverse as blackmail, trademarks and warning labels.”
This description is given by Peter Tiersma, Professor of Law at Loyola Law School in Los Angeles, and the author of Legal Language. He says: “The field of forensic linguistics has been growing in prominence in the past couple of decades. There is now a professional organization that bears this title (the International Association of Forensic Linguists), as well as the International Association of Forensic Phoneticians, which is closely related. There is at least one journal (the International Journal of Speech, Language, and the Law), formerly known as Journal of Forensic Linguistics, and there seem to be two or three conferences a year devoted to the topic. Programs in forensic linguistics are offered at several universities (mostly in the United Kingdom), and there are online courses of study either in existence or in the planning stages. Oddly, the scope of the term “forensic linguistics” remains somewhat vague.”
Here is what Dr Tim Grant has to say. He is Deputy Director and Senior Lecturer at the Centre for Forensic Linguistics, Aston University, UK. He also makes some very interesting comments about interpreting for the police.
