This thesis attempts to investigate the structure of Libyan Arabic discourse in general and interviews as a text-genre text-form in particular. This investigation includes conjunctions and their influence on the cohesion of interviews and certain other textual phenomena, i.e. repetition, parallelism and their unequivocal significance in text cohesion. To this effect, random samples were taken from two Libyan Arabic interviews, i.e. sample text 1 and sample text 2 to who how the structure of these texts is made up. To achieve these objectives, this study uses a semantic, structural and pragma-semio-textual approach to analyse and then translate the texts chosen, as language in this study is considered to be a form of behaviour (Halliday 1973) that cannot be studied in isolation from its social, cultural and contextual contexts in which it is used. Our textual analysis has shown interesting results. First, interviews have their own generic structure and such structure is presented in specific stages. Second, interviews favour the cohesive type of lexical repetition not only for cohesion purposes but also for persuasive functions as well. Third, interviews use many parallel constructions for conviction and persuasive functions.
