Abstract
This essay aims at questioning different aspects of narrative and description by means of the model of discourse analysis presented in Roulet & al. . After showing the necessity of a unified approach to the structure of different discourse types and the problem of discourse heterogeneity, the author examines the following problems: the distinction between a relation and a narrative and the different modes of insertion of those two types of discourse in an exchange structure, the hierarchical and argumentative structure of narrative, the distinction between narrative and deliberate discourses, the insertion of dialogues in narrative and the co-construction by the interlocutors of a narrative in dialogue. He then sets up a distinction between different types of descriptions and analyses the hierarchical and argumentative structure of description. He concludes with a recapitulation of the diverse modes of integration of narrative, relation and different types of description in discourse
