Paraguayan Guarani, or simply Guarani (avañe'ẽ), is a language of South America that belongs to the Tupi–Guarani branch of the Tupian language family. It is one of the two official languages of Paraguay (along with Spanish), where it is spoken by the majority of the population, and where half of the rural population are monolingual speakers of the language.
Variants of the language are spoken by communities in neighboring countries including parts of northeastern Argentina, southeastern Bolivia and southwestern Brazil. It is a second official language of the Argentine province of Corrientes since 2004 and the Brazilian city of Tacuru since 2010. Guarani is also one of the three official languages of Mercosur, alongside Spanish and Portuguese.
