The study aims to identify the linguistic and discursive characteristics of each form of testimony in order to understand how witnesses construct and transmit memory. Particular attention is given to the linguistic mechanisms used to highlight dominant ideas according to Dominique Maingueneau, as well as to dialogism as developed by Mikhail Bakhtin. The corpus consists of written and oral testimonies produced by Algerian freedom fighters and victims of colonialism. The analysis reveals that oral discourse is marked by strong emotional and interactive dimensions, whereas written discourse tends to be more reflective and structurally organized. The research also highlights the role of testimonial discourse in preserving collective memory and denouncing colonial violence.frtestimonial discourseoral testimonywritten testimonydialogismcolonial memorydominant ideasdiscourse analysisAlgerian WarThesis
