"In this important new study, Sandro Sessarego provides a syntactic description of the Afro-Bolivian Spanish determiner phrase. Afro-Bolivian Spanish is one of the many Afro-Hispanic dialects spoken across Latin America and, from a theoretical point of view, is rich in constructions that would be considered ungrammatical in standard Spanish. Yet these constructions form the core grammar of these less-prestigious, but equally efficient, syntactic systems. Because of the wide variety of their usages, Sessarego's study of these contact varieties is particularly valuable in developing and refining theories of syntactic microvariation. This dialect presents phenomena that offer a real challenge to current linguistic theory. The Afro-Bolivian Spanish Determiner Phrase elaborates on the importance of enhancing a stronger dialogue between formal generative theory and sociolinguistic methodology, in line with recent work in the field of minimalist syntax. Sessarego's study combines sociolinguistic techniques of data collection with generative models of data analysis to obtain more fine-grained, empirically testable generalizations"--
