Abstract : The thesis aims at studying the argumentative modificators and their function in language. The theory of argumentation in language (ADL) which was founded and institutionalised in the seventies by Oswald Ducrot and Jean Claude Anscombre profoundly treated the argumentative modificators because of their important role in discourse.
According to this theory, the fundamental function of language doesn't consist in describing reality, but in argumentation. The mdificators are defined as lexical words which can either strengthen or weaken the argumentative potentialities of language's predicats ; they highlight the diverse orientations and the argumentative strategies of discourses. In fact, the argumentative modificators have been highly developed in line to development of the theory itself. There are actually two versions of the theory of argumentation in language: the first on is the topique version where the meaning of words consist of a package of topoï. The usage of the modificators with the nouns for example may realise or derealise their applicability in the discourse.
The second version of the theory replaces the topoï by semantic blocs which accordingly consist in different semantic constructions created by the discourse.
The study is based on the analysis of a lot of different selection of fairy tales abstracted from “Les fables” of La Fontaine.
