The aim of the course is to provide the student with a broader view of the concept of grammar, with regard to the Portuguese language in its pluricentric context. The study of the different linguistic approaches, formalist and functionalist, which underlie the texts taken into consideration in the course, aim to place the student in the universe of linguistic analysis in the different sociolinguistic contexts of Portuguese expression. Furthermore, the student will have to be able to locate Brazilian Portuguese from a historical, sociolinguistic and political point of view, making use of the moments of formation of the Brazilian Nation State, of the various linguistic and social identities that gave it its origin and which are constantly changing.
