A branch of onomastics that studies the origins of proper names, the examination of anthroponymy in Jean Genet's stories focuses on the links between the instability of the author's name and the geographical mobility of his relationships with different social strata. Through a morpho-semantic analysis of the author's multiple appellations, the evolution of this fabulist and mythomaniac writer's names in his narratives draws its essence from his broken biography, which he transcends through backward sublimation to set himself up as characters both evil and illustrious.
