Forensic linguistics

Forensic linguistics is a branch of applied linguistics. It uses linguistics to help give evidence in a trial. One aspect of it is to identify a person by analysing the language that person uses. Other questions might be about finding the author of a text (or telling whether two texts were done by the same person).

Stefan Zweig committed suicide, in 1942. This is his suicide letter. Forensic linguistics is also about finding out if such a letter was written by the person who committed suicide.
