This thesis introduces yupumÃ¡, a term in Hantxa Kuin language which emerged from and became central to my fieldwork with the indigenous Huni Kuin of Acre in Brazilâs lowland Amazon Basin. This indigenous word does not have a direct translation into Portuguese or English and also presents a problem of definition at the semantic and pragmatic level for my Huni Kuin interlocutors. With their help, I propose the working definition of yupumÃ¡ as a notion that refers to those processes through which knowledge emerges within and through different forms of action. I explore how knowledge emerges from and through the range of situated practices covered by the term yupumÃ¡, and how these shape and mediate experience and how they can be directly applied and incorporated into the practice of ethnographic and creative filmmaking. The film YupumÃ¡, the counterpart to this dissertation, shows daily life in a Huni Kuin village where ritual and myth are intertwined and seen through the lens of the notion of yupumÃ¡ (https://vimeo.com/461126717 Password: Agistri).
