Spanish and Portuguese parallels
This paper investigates variable number agreement phenomena across the Determiner Phrase (DP) of two non-standard varieties of Spanish and Portuguese spoken in Latin America: Afro-Bolivian Spanish (ABS) and Popular Brazilian Portuguese (PBP). In line with recent studies in the field of minimalist syntax (Adger & Smith, 2005; Sessarego, 2014), this article combines sociolinguistic techniques of data collection with generative models of analysis to obtain more fine-grained, empirically testable generalizations. The presence of an impoverished agreement system in these two varieties is studied in light of recent linguistic proposals on the nature of default values (Harley & Ritter, 2002). These findings are generalized to other grammatical constructions, which systematically occur across a number of vernacular dialects.
