"Nós concordamos em pessoa e número, porém, nós discorda bastante." A study of first person plural pronouns in BP based on a popular speech corpus

The traditionally called "nominative forms" of pronouns are also oblique representatives without any marginality in its acceptance in Brazilian Portuguese (BP). There is no univocal correspondence between a pronominal form and a unique casual function, as expected in European Portuguese (EP). We also argue, in this work, the plural first-person pronouns integrate the vernacular system of BP pronouns and do not compete with each other. Based on the assumptions of the Generative Theory, we argue that the grammatical change, related to the opposition of a system composed by six grammatical persons toward an opposition of first and third person singular, has as consequence a change in the grammatical features of the pronouns that are no longer marked as nominative in the lexicon; so, the Brazilian vernacular pronoun paradigm is characterized by a flexional paradigm and a concordance system distinct from EP.
