This article provides some reflections on issues inherent to the discourse recorded in the book Metade Cara, Metade Máscara (Half Face, Half, Mask). Our aim is to accentuate the regularities filed in the discursive formations that characterize Eliane Potiguara’s discourse, orienting her poetry and her word in movement, guiding us through the theorists Michel Foucault and Eni Orlandi to, through Potiguara’s discourse, observe the discursive order that challenges her. We aim to observe what subject she is converted into when she takes possession of the word and gives vent to the life of the Brazilian indigenous peoples. Through the analysis of this work, it can be seen that whether through her poetic or autobiographical discourse, or her journalistic writing of information, Potiguara exalts the determination and firmness of the struggle of the indigenous peoples.
