The purpose of this B.A. thesis is to provide an analysis of Forensic Linguistics in theory and more importantly in practice. The theoretical part of this thesis explains the main goals of Forensic Linguistics and defines the meaning of Forensic Linguistics. One of the main fields in Forensic Linguistics is Forensic Phonetics, which will also be further explored in the first chapter. Moreover, it is also important to discuss the history and establishment of Forensic Linguistics and this thesis also explains how Forensic Linguistics has developed in major English speaking countries. Furthermore, the types of texts and documents that forensic linguists are asked to analyze are mostly those which are related to certain crimes. In this thesis in particular, threat texts, suicide notes and emergency calls are the types of forensic texts which will be analyzed theoretically. I will also provide my analysis of a few examples for each of those texts. The sources for each of the examples will be provided in footnotes.
