This paper explores the production of new meanings linked to written practices in the Wichi language in the Impenetrable Chaqueño (Argentina). Through collaborative ethnography examining different collective experiences and points of view, we study changes in writing in connection with changes in the access, distribution and availability of written practices in the Wichi language, and particularly in connection with social processes that position the Wichi people as key agents. Voice and agency are considered in order to explain meaning-making of language practices that are central but at the same time peripheral, and which seem to challenge, from the margins, social relationships between languages and people that hitherto seemed to be immovable.
