This study presents language as a form of social expression through which feelings, ideas and thoughts are signified in a Culture. However, distinct groups belonging to the same society may define those factors in different ways, giving rise to a phenomenon called 'Multiculturality'. Therefore, thinking about this cultural diversity and taking into account the socio-emotional factors present in the Brazilian National Common Core (Base Nacional Comun Curricular/BNCC), this article aims to theoretically address critical interculturalism and multiculturalism alongside with socio and emotional intelligences in second language learning within the current perspective of Brazilian Education.
