English for Specific Purposes (ESP) has been around since the sixties. Its emergence was due mainly to the revolutionary changes that the world witnessed after the end of the second World War. 

                 This course aims at equipping 3rd year English language students with the suitable knowledge so that they become able of explaining what ESP is about, explaining some of its main concepts and use an ESP course design to transmit relevant knowledge.
