This dissertation proposes an analysis of the word "sea" within the novel Dom Casmurro (1899) by Machado de Assis, using as a foundation the principles of language as described by Cognitive Linguistics (a theoretical group initiated in the United States by independent scholars such as George Lakoff and Charles Fillmore) and the application of these concepts to literature according to Cognitive Poetics, particularly Stockwell's (2002) perspective. The analysis is conducted in relation to the intertextual context of the novel, and the translation suggested at the end of the analysis does not encompass the entire novel nor all mentions of the word, but rather selected excerpts deemed relevant. The research's purpose is to investigate the translation process through the lens of cognitive studies and demonstrate the potential advantages of integrating the two fields (thus, the process itself is the focus). For understanding the notion of context, the theory of Frames (FILLMORE, 1982), the concepts of MCI and Domain (LANGACKER, 1987), and the theory of Mental Spaces (FAUCONNIER, 1994) are employed. To better analyze the interaction between the two literary worlds in terms of intertextuality, the theory of Conceptual Blending (FAUCONNIER, 1997) is used, aiming primarily to explore the theoretical potential in the intersection of cognitive studies and the field of translation.
