This article aims to show the important role played by the Spanish language in the affirmation of the spanish identity of the author Emmanuel Roblès, in his autobiographical novel, written in French: Jeunes Saisons. It is about a narrator-character, of Spanish origin, telling the scenes of his childhood in native Oranie. This narrator uses some expressions of Spanish origin, considered intrusive to the French language. These expressions acquire a symbolic value inside the text.We will also show that this use of the Spanish language by the narrator-character, constitutes a trace of the roots and identity of the author.
