This research aims to answer the question: how can one speak of a decolonial linguistics focused on the linguistic phenomena involved in this process? To this end, a pragmatic discourse approach will be used, in which discourse, “in its reality as a material thing spoken or written” (Foucault, 1996, p. 8), is the object to be analyzed; that is, this study starts from the critique of immanent linguistics, disconnected from such phenomena, amidst the rise of the Global South, multiculturalism, and the glottopolitical challenges in this [ancestral] Post-future. At the end of the discussion, it is concluded that the emergence of this decolonial linguistics, which arises primarily with Fanon and Césaire, constitutes not only a theoretical response to the colonialities of language, but a political and ontological gesture of restitution of the voice and place of speakers from the zone of non-being who were affected by the existential abyss imposed by European colonialism (Fanon, 2008).
