Across the world, nations manage their borders in various ways. Brazil and Uruguay share a non-militarized dry border, which creates a range of unique challenges and assets for that region. Through historical, linguistic, and cultural context as well as ethnography-inspired mixed method research, this paper demonstrates that the border region serves as an area of cultural blending. While elements of national affiliation are still present, at times, semiotic and linguistic elements are neither Brazilian nor Uruguayan, but have taken on their own identity.
