Our thesis questions the oral transmission process of Berber tashelhiyt Moroccan tales, collected in Morocco and France in an intercultural and interlingual situation. We focus on the negotiated dimension of the process of transmission, that is to say the activity of mediation which reinterprets the tale for the other – foreigner to the tale’s origin culture – and into his language. We analyse this activity through its emergence, its failure, and its adjustment to the other via the marks left on the surface of texts. These marks highlight some « sensitive » discourse parts that are impacted on by various levels of otherness : linguistic, cultural, interdiscursive and interlocutive. We point out a set of procedures of (re)mediation that assures the narrative continuation, the mutual understanding based on specific added details and expose the co-constructed nature of the narration and of the interculturalrelation. Our analysis reveals a « meta » level of mediation that registers the « tale telling » in the tale, revealing how enunciators elaborate storytelling, become the representative of their own community, with more or less personal authority and involvement, how they tell and show themselves, how they evaluate the state of the intercultural relation and occupy a median position from which they shift the tale. The observation of various forms of transmission reveals different ways to make this mediation and reports a tale variation in intercultural situation, in continuity with an oral tradition
