Paraguayan Spanish (Spanish: español paraguayo) is a version of the Spanish language spoken in Paraguay. In addition, it influences the speech of the Argentine provinces of Misiones, Corrientes, Formosa, and, to a lesser extent, Chaco.
The Guarani language is co-official with Spanish in Paraguay, and most Paraguayans speak both languages. Guaraní is the home language of more than half the population of Paraguay, with higher proportions of its use in rural areas, and those who speak Spanish at home slightly in the majority in the cities.
The Swedish linguist Bertil Malmberg visited Paraguay in 1946 and observed several features of Spanish pronunciation that he attributed to Guaraní influence. The Guaraní origin of many of these features, however, has been questioned by other researchers, who document them in dialects not in contact with Guaraní.
Characteristics
The unique features of Paraguayan Spanish developed in part due to Paraguay's early isolation; for example, José Gaspar Rodríguez de Francia, the country's president until 1840, sealed Paraguay's borders. Other experiences with geographic, political, and economic isolation relative to its neighbours allowed Spanish spoken in Paraguay to develop its own unique characteristics, even apart from the wide-ranging influence of Guarani.
Paraguayan Spanish shares many similarities with Rioplatense Spanish (that is, the variety spoken in Argentina) such as the use of the voseo and various words and phrases.
