Presupposition and Implicature in English and Arabic Editorials

The use of implicature and presupposition is an integral part of all human communication. The notions ¿presupposition and implicature¿ can be achieved in media texts. One of the goals of writers must be to persuade their readers of the validity of their basic claims. However, they are particularly used in editorial texts because they help establish represented realities as convincing. Presuppositions are background assumptions embedded within a sentence or phrase. These assumptions are taken for granted to be true regardless of whether the whole sentence is true. Like presuppositions, implicatures lead the listener or reader to infer something that was not explicitly asserted by the speaker or writer. However, unlike presuppositions, implicatures operate over more than one phrase or sentence and are much more dependent on shared knowledge between the speaker or writer and the listener or reader and on the surrounding context of the discourse.
