The purpose of this Article is to show that the inner exile constitutes the background of the majority of Tierno Monénembo’s texts. As such, it is a study of the social and psychological life of the characters. For this reason, it aims to depict that apart from the distance or the geographical exile and the linguistic exile, the interior exile appears in two different manners under the pen of the Guinean author. It is defined, on the one hand, as compared to the space ranging between the borders of a country or the country itself and the fact of being foreigner on one’s own motherland and, on the other hand, in connection with the state of mind or the psychological life of the subject. It is, for this reason, a shrinking on one’s self or a distance compared to reality, i.e. a withdrawal or simply an escape in the imagination. Still, the reflexion leads to the global analytical result according to which the inner exile is the worst of all sots of exile.
