This study offers a linguistic analysis of the Afro-Mexican Spanish spoken in the Costa Chica region, one of the largest Afro-Mexican enclaves. The present investigation not only accounts for the Afro-Hispanic linguistic remnants of this Spanish variety, but also examines the current linguistic characteristics and sociolinguistic status of this speech area on the brink of extinction. Additionally, this monograph proposes a Rhizomatic Linguistic Model to interpret data derived from contact situations.
