In Argentina it is known as Western Argentine Guaraní, while in Paraguay it is locally known as Ñandeva. However, outside Paraguay and specifically in Brazil, Nhandeva refers to Chiripá Guaraní.

Eastern Bolivian Guaraní is one of a number of "Guaraní dialects" sometimes considered distinct languages. Of these, Paraguayan Guaraní is by far the most important variety and it is often referred to simply as Guaraní.
