Western Bolivian Guaraní

Western Bolivian Guaraní, known locally as Simba and Simba Guaraní, is a Guaraní language spoken in Bolivia, in the Chuquisaca Department north of the Pilcomayo River.

Western Bolivian Guaraní is one of a number of "Guaraní dialects" considered distinct languages by Ethnologue: Chiripá, Eastern Bolivian Guaraní, Mbyá Guaraní, Aché, Kaiwá, Xetá, and Paraguayan Guaraní. Of these, Paraguayan Guaraní is by far the most widely spoken variety and it is often referred to simply as Guaraní.
