Using qualitative methods, observations, interviews, and focus groups, conducted in Tlemcen’s public and private healthcare settings, the research shows that doctors shift between Algerian Arabic and French depending on patient needs, emotional context, and clinical demands. Code switching helps improve clarity, empathy, and authority. Patient cues play a major role in shaping doctors’ language strategies. The study underscores the importance of linguistic sensitivity in delivering effective, patient-centered care in Algeria’s multilingual healthcare environment.en-USMultilingualismCode-switchingHealthcare communicationAlgeriaThesis
