Duplicação do sujeito no português brasileiro: uma análise dos pronomes resumptivos

This paper investigates some specific syntactic, prosodic, and morphological properties of subjects and pronouns in Brazilian Portuguese (BP) subject doubling (SD) constructions. The study demonstrates that neither the subject nor the pronoun exhibits uniform behavior within this construction. Adopting the “one feature, one head” principle (Kayne, 2005), this research argues that the subject may occupy positions in both the CP domain, as a topic, and the TP domain, as a grammatical subject. Furthermore, based on the grammatical properties of pronouns, this study posits that pronouns in BP SD can function either as strong or weak forms, aligning with the analysis of Cardinaletti and Starke (1994). The hypothesis is that strong pronouns can occupy Spec,TopP (Rizzi, 1997) or Spec,SubjP (Cardinaletti, 2004), similar to the subject, whereas weak pronouns, by contrast, occupy Spec,TP.Keywords: Brazilian Portuguese.
