Expressing love is also a language through which we communicate to others and ourselves that which we are feeling. Oriented by the theoretical sociology projects of Marcel Mauss and Gabriel Tarde, this thesis evinces the languages of the grammar of love among young middle class women in the city of Rio de Janeiro, considering such particular aspects to youth culture, as social representations that circulate in media. Resorting Moscovici and his theory of social representations, the emotional discourse is achieved by the interpretative analysis of content and practices of ethnographic inspiration to indicate, through individual narratives, the signs of stability and those of possible ruptures in the languages that they appropriate at the beginning of the second decade of the 21st century. The evidence of Gilberto Velho, Claudia Barcelos Rezende and Maria Cláudia Coelho and the micropolitics of emotions are also extremely relevant, contributing to reveal the languages presented at the conclusion of the research, including sentimental expressiveness, the deromanticization of relationships and mediated affectivity.
