The research-action project EquiLing analyses the role that language plays in the construction of social inequalities and looks for ways to reverse sociolinguistic injustices. For this, during more than four years, EquiLing’s research teams have collaborated to carry out transformative actions in Catalonia, the Basque Country, Galicia and Madrid. This interactive resource gathers the main results of the project. To access the resource that allows you to see the dynamic presentation and click on each of the links (documentaries, audios, publications, etc.) you will have to write at least one letter.
