It aims to analyze the role of code-switching between French and Algerian Arabic in the expression of emotions and the construction of social identity. The corpus consists of ten speech extracts collected from interviews, press conferences, and sports interactions broadcast on YouTube and TikTok. The study adopts both quantitative and qualitative approaches to identify the forms of code-switching and their sociolinguistic functions. The findings reveal that players frequently use Algerian Arabic to express emotions such as joy, hope, frustration, and pride, while French is mainly used to structure discourse and discuss technical and professional aspects. Code-switching therefore appears as a discursive strategy that enables players to adapt their communication to the media context while asserting their social and cultural belonging. This linguistic practice also reflects the multilingual reality of Algerian society and the social representations associated with the languages involved.frSociolinguisticscode-switchingFrenchAlgerian Arabicexpression of emotionssocial identitysports discourseThesis
