This paper will provide a detailed geographic analysis of the reach of yeísmo in a number of Latin American republics (El Salvador, Honduras, Panamá, Cuba, Ecuador, Perú, Bolivia, Chile, Argentina and Uruguay) in order to present an overview of the extent and development of this phonetic phenomenon in the Spanish spoken in America. It thus aims to build on recent studies that have attempted to assess the distribution of this feature throughout the Spanish-speaking world. [ABSTRACT FROM AUTHOR]
