Applied linguistics includes forensic linguistics as one of its components. People in this profession are responsible for examining laws, legal procedures, language in the courtroom, and evidence presented in both civil and criminal cases. Applied linguistics in this context differs from other types in that data collection is unnecessary as it is readily available. The responsibility of a linguist entails the use of a range of linguistic tools, including but not limited to pragmatics, phonetics, morphology, syntax, discourse analysis, language change, stylistics, semantics, lexicography, sociolinguistic variation and graphemics, in order to work with pre-existing data. Forensic linguists approach their work from a legal standpoint and use linguistic techniques to address legal matters. In order to be recognised as experts, linguists who provide testimony in trials must satisfy specific legal criteria. During forensic linguistic analysis, it is incumbent upon the linguist to impart knowledge to legal practitioners, including but not limited to judges, jurors, and lawyers regarding the fundamental principles of linguistic analysis as they relate to the legal issues under consideration. The increasing prominence of forensic linguistics suggests that applied linguistics is broadening its scope beyond conventional emphasis on language acquisition, instruction, and assessment, thereby constituting a favourable advancement. The study shows how language is essential to the judicial system and how it ironically fosters injustice. Therefore, the significance of critical legal analysis and the participation of linguists is demonstrated
