(En): We deal here with a specific mix of languages, especially a mix of Modern Classical Arabic (fuṣḥā) and Moroccan Arabic (dariža) as it is practiced in Moroccan audiovisual media. First, the terms of fuṣḥā and dariža are presented within the Arabic language typology and contextualized in the Moroccan sociolinguistic landscape. Then, we discuss this 'mixed-styles' (Mejdell 2006) on a corpus from programs broadcast on Moroccan channels. We focus on formal and syntactic characteristics of this language practice, in particularly on the tense-aspect-mood markers. The question is to know if this 'mixed-styles' develops a norm, a standard that is required in formal oral situations.
