Technical description: Forensic linguistics is the
study, analysis and measurement of language in
the context of crime, judicial procedure, or disputes
in law, including the preparation and giving of
written and oral evidence.
Explanation: The study of any text or item of
spoken language which has relevance to a criminal
or civil dispute, or which relates to what goes on in
a court of law, or to the language of the law itself.
Thus the linguist may be called upon to analyse a
very wide variety of documents, e.g. agreements
relating to ancient territorial disputes, the quality of
court interpreting, an allegation of ‘verballing’
(claims by defendants that their statements were
altered by police officers), a disputed will, a suicide
note, a ransom demand, etc.
