Hence, it dialogues with different researchers such as Antunes (2007), Bagno (2007), Bagno (2015), Bortoni-Ricardo (2005), Coelho (2015), Labov (2008) and Santos (2008), as well as with the Curricular Parameters (BRASIL, 1996) and the National Curricular Common Base (BRASIL, 2017). This is a bibliographic research (LIMA; MIOTO, 2007) that selected the most relevant works on the heterogeneity of the language available on digital platforms such as: Google Scholar, Institutional Repository of the Federal University of Alagoas, Periodical Portals available through Capes-MEC and Scielo, among others. After the reflections about the selected works, we present some Portuguese teaching proposals in order to deconstruct the linguistic prejudice.ptHeterogeneidade linguísticaPreconceito LinguísticoEnsino de Língua Portuguesa.Trabalho de Conclusão de CursoLINGUISTICA, LETRAS E ARTES
