This paper deals with two scientific approaches of the language used in a pedagogical way to help students of French language in specialized communication to discover how to process the language and try to enter after all a semantic dimension that is the main goal of discourse analysis. On the one hand, the American school helps us to describe the syntax. On the second hand, the French school of discourse analysis helps us to understand the structure of the discourse. We try to show that Chomsky’s ideas are not against Culioli’s but are both complementary: as well as every citizen nowadays should be able to suggest a synthesis if dares to confront two ideas. European citizenship seems to be now valuable.
