Based on issues raised by Maria Aparecida Moura and Bianca Santana's lectures at the meeting Decoloniality and Information Science: dialogical paths, the article makes an initial comparison between three distinct but related concepts: intersectionality, crossroads and exuzilhada. For this, it takes as its main reference texts by Patricia Hill Collins and Sirma Bilge, Leda Maria Martins and Cidinha da Silva, respectively. Along the way, it assesses how each concept seeks to represent the complexity and heterogeneity of marginalized or rarefied experiences. Considering some dilemmas of the first concept, it understands that the last two can suggest a non-essentialist concept of representation. In any case, the article marks the beginning of a discussion, open to other paths and transformations, underlining the dialogue as a "moving vital process"
