Foundations of Forensic Linguistics
What forensic linguistics is, where it came from, and the landmark cases and scholars that defined it as a discipline. Covers the Evans case and Jan Svartvik's corpus analysis, Malcolm Coulthard's work, and the field's relationship to general linguistics.
Start module- Introduction and Scope of Forensic LinguisticsForensic linguistics applies the tools of language science to legal and investigative questions, from identifying who wrote an anonymous threat to explaining why a jury instruction makes no sense.13 min
- History and Landmark Cases: Svartvik, Evans, and CoulthardThe discipline of forensic linguistics crystallised around a handful of landmark cases in the United Kingdom and United States, most notably Jan Svartvik's 1968 analysis of Timothy Evans's confession statements.13 min
- Core Linguistic Concepts for Forensic WorkA working primer on the linguistic concepts, registers, idiolect, dialect, corpus methods, and discourse structure, that underpin forensic language analysis and explain why systematic counting beats native-speaker intuition in court.15 min
Module 26 hrs5 topics
Authorship Attribution and Stylometry
The science of determining who wrote an unknown text: function-word profiling, n-gram analysis, stylometric distances, machine-learning classifiers, and the major real-world cases that tested the methods.
Start module- Authorship Attribution: Principles and MethodsAuthorship attribution is the forensic effort to identify who wrote a text by measuring idiosyncratic linguistic habits. This topic covers the theoretical foundation of the idiolect, the features analysts extract, and how closed-set and open-set problems differ.11 min
- Stylometry and Statistical Distance MethodsStylometry translates authorial habit into numbers and measures the distance between writing samples. This topic covers Burrows's Delta and its variants, multivariate visualisation methods, machine-learning classifiers, and the validation requirements that determine whether stylometric evidence is legally defensible.11 min
- The Unabomber Case: Stylometric Attribution at ScaleThe Unabomber investigation produced one of the most scrutinised forensic-linguistic attributions in history. This topic analyses the linguistic features that connected the Manifesto to Ted Kaczynski's private writings, the role of the public tip, and what the case reveals about both the power and the limits of stylometric evidence.11 min
- The JonBenet Ramsey Ransom Note: Authorship in a High-Profile CaseThe 2.5-page ransom note in the 1996 JonBenet Ramsey murder is one of the most analysed questioned documents in American forensic history. This topic examines what features analysts studied, why the note's characteristics are linguistically unusual, and why the case became a textbook lesson in the risks of small corpora and analyst bias.11 min
- Disputed Authorship in Literature and HistoryDisputed authorship in literary and historical texts ranges from the founding scientific test case of the Federalist Papers to contemporary unmasking of pseudonymous novelists. This topic traces the development of stylometry through canonical studies, examines the ethics of attribution without consent, and defines the different standards of evidence required for scholarly publication versus court.13 min

Threat, Ransom, and Suicide Note Analysis
How forensic linguists analyse threatening communications, ransom notes, and suicide notes: credibility assessment, authorship features, comparison with genuine examples, and the limits of what linguistic analysis can establish.
Start module- Threatening Language: Taxonomy and AnalysisA working guide to how forensic linguists define, classify, and evaluate threatening language, distinguishing credible threats from venting and placing linguistic analysis within broader threat-assessment frameworks.15 min
- Ransom Note Analysis: Features, Authenticity, and AttributionHow forensic linguists examine ransom and extortion notes for authenticity, authorship attribution, and the structural features that distinguish genuine demands from fabrications.13 min
- Suicide Note Analysis and AuthenticityForensic linguists are called on to determine whether a note found at a death scene is a genuine communication from the deceased or a fabrication, with significant consequences for insurance, homicide investigation, and legal proceedings.15 min
Module 46 hrs4 topics
Language of the Law
How legal texts are written, how jurors and defendants misunderstand them, and how linguistic analysis serves interpretation disputes in contracts, statutes, Miranda rights, and jury instructions.
Start module- Legal Language: Features, Problems, and Plain Language ReformLegal English is dense, archaic, and often incomprehensible to the people it governs. This topic traces why legal language evolved that way and examines the global plain-language reform movements trying to change it.14 min
- Miranda Rights and Comprehension: What Suspects Actually UnderstandThe Miranda warning is recited millions of times each year, but empirical studies show that large proportions of suspects do not understand the rights they are waiving. This topic examines the linguistics and psychology of Miranda comprehension, and what the research means for false confessions and the validity of waivers.14 min
- Jury Instructions: Comprehension Problems and Linguistic RemediesJury instructions are the legal rules that guide deliberation, but empirical research consistently shows that jurors misunderstand key standards like 'beyond a reasonable doubt'. This topic examines the comprehension failures and the linguistic fixes that work.14 min
- Contract Disputes and Statutory Interpretation: The Linguist as ExpertWhen courts dispute what a contract clause or statute actually means in ordinary language, forensic linguists offer corpus-based empirical evidence about word usage. This topic covers the methods, landmark cases, and the limits of what linguistic expert evidence can and cannot decide.15 min

Discourse Analysis in Police Interviews and Confessions
How language works in custodial interrogations: power and control, question types, false confession mechanisms, the PEACE model, SCAN statement analysis and its critique, and how recorded interviews become evidence.
Start module- Police Interview Discourse: Power, Questions, and ControlHow language creates and reinforces power in police interviews: the asymmetry of question types, reformulation, and the rights suspects rarely fully exercise.12 min
- False Confessions: Linguistic Mechanisms and DetectionWhy innocent people confess and how their language betrays it: the three false-confession types, contamination of content from interrogator questions, and what linguistic markers can and cannot tell investigators.13 min
- SCAN Statement Analysis: Claims, Methods, and the Scientific CritiqueScientific Content Analysis (SCAN) claims that deceptive statements have detectable linguistic patterns, but empirical testing consistently finds its accuracy at or below chance, raising serious questions about its continued use in investigations.10 min
- The PEACE Model, the Cognitive Interview, and Investigative LinguisticsThe PEACE interviewing framework and the Cognitive Interview technique replaced coercive interrogation in England and Wales and beyond, with the CI's linguistic structure producing markedly better witness accounts than leading or closed questioning.12 min
Module 66 hrs3 topics
Plagiarism, Text Reuse, and Trademark Disputes
Computational and manual methods for detecting text reuse in academic, commercial, and legal contexts, and the linguistic analysis of trademark and brand-name disputes.
Start module- Plagiarism and Text Reuse: Detection Methods and EvidenceHow forensic linguists and computational tools identify verbatim copying, paraphrase, mosaic plagiarism, and translation plagiarism in academic and IP disputes, and what an expert witness adds beyond a similarity score.11 min
- Trademark and Brand-Name Disputes: Linguistic EvidenceHow forensic linguists contribute phonological, semantic, and corpus-based analysis to trademark litigation, from likelihood-of-confusion assessments to genericness disputes over brand names that have entered everyday language.13 min
- Linguistic Profiling and Dialectology as EvidenceHow forensic linguists use documented dialect and accent features to infer a speaker's regional origin or social background, the sharp distinction between legitimate dialect analysis and racially discriminatory voice profiling, and the probability limits on what such analysis can establish in court.14 min

Online Communication, Grooming, and Disputed Digital Texts
Language evidence in digital contexts: text-messaging style, online grooming patterns, disputed authorship of digital communications, and the emerging challenge of AI-generated text.
Start module- Text Messaging and Digital Language as EvidenceDigital communication channels from SMS to messaging apps have created a new category of linguistic evidence, raising distinct challenges around authenticity, authorship attribution in short texts, and the recovery of deleted messages.14 min
- Online Grooming: Linguistic Patterns and EvidenceOnline child sexual grooming follows a recognisable linguistic structure across cases, and forensic linguists can identify its stages, distinguish genuine grooming from fantasy or role-play, and assess who steered a conversation in undercover officer evidence.12 min
- AI-Generated Text: Authorship, Detection, and the New Evidential FrontierLarge language models impose their own statistical signature on text, disrupting traditional authorship attribution, while AI detection tools carry documented false-positive rates and no validated court-ready method yet exists for determining whether a specific human used an LLM to write or rewrite content.15 min
Module 86 hrs3 topics
Courtroom Discourse, Interpreting, and Professional Ethics
The language of the courtroom: witness examination, lawyer questioning strategies, cross-examination discourse, interpreter accuracy in legal settings, and the ethical and quality standards that govern forensic linguistic practice.
Start module- Courtroom Discourse: Examination, Cross-Examination, and Question ControlThe courtroom is one of the most linguistically constrained environments a person ever enters. This topic examines how the structure of questioning controls what witnesses can say and why that matters for truth-telling.13 min
- Interpreter Issues in Legal Settings: Accuracy, Role, and FailuresThe right to an interpreter in criminal proceedings is a fundamental guarantee in most legal systems, but what 'accurate interpretation' actually means linguistically is far more contested than courts typically acknowledge.11 min
- Ethics, Quality Standards, and Expert Witness PracticeForensic linguists who testify as experts carry duties to the court that override their obligations to the instructing party. This topic examines the professional standards, admissibility frameworks, and practical safeguards that govern expert witness practice in forensic linguistics.14 min
