This paper seeks to contribute to the intercultural reconstruction of the school linguistic human right to literacy, questioning the monovalent and universalizing nature with which this right is inserted in the social horizon of the dominant groups of global capitalism. Upon a theoretical ground that articulates discourses from the Bakhtin Circle, New Literacy Studies, Applied Linguistics and Cultural Studies, the analysis of data interprets discourses about that issue by the Guarani teachers of the Itaty Indigenous Primary School, located in the Guarani village of Morro dos Cavalos (Santa Catarina, Brazil). Those discourses interculturally reconstruct the right to literacy as the right to the school register of their cultural heritage (claimed upon the transformations of economic basis of the community's forms of utterance and legitimated practices of knowledge generation and transmission), and as a "weapon of defense and survival" with which to struggle for fuller sovereignty over their forms of utterance and, inseparably, over their economy.
