Key Roles of Forensic Linguists
They analyze written and spoken language in a variety of legal settings. They are using their knowledge of grammar, style, vocabulary, and even dialects to:

- Evaluate witness statements: By analyzing witness statements, forensic linguists can assess their accuracy and reliability. They can look for inconsistencies, contradictions, and indicators of bias or fabrication.
- Investigate hate speech and online harassment: Linguists can analyze online messages and social media posts to determine if they constitute hate speech or online harassment. They can identify the target of the abuse, the nature of the language used, and the potential harm it could cause.
The impact of forensic linguistics can be far-reaching, influencing: Investigations, Court proceedings, and Legislation The work of forensic linguists plays a crucial role in the pursuit of justice.
Real-life examples of Forensic Linguistics and Applications
