This chapter provides an overview of the main phenomena of syntactic variation that correspond to Caribbean Spanish. It also develops a critical review of the formal analyses proposed in the literature to account for them. After a short theoretical introduction, the presentation of the data is organized into two groups. The first is devoted to constructions that are characteristic of the area under study (including Mexico, Central America, Antilles Islands, Colombia, and Venezuela). The second reviews constructions also found in other territories, but more frequently attested in the Caribbean area. The set of constructions studied relates to major aspects of Spanish grammar, such as the pronominal system, wh- constructions, infinitival subjects, agreement, possessives, cleft constructions, and negation, among others.
