Tariana language

Tariana (also Tariano) is an endangered Maipurean (also known as Arawak) language spoken along the Vaupés River in Amazonas, Brazil by approximately 100 people. Another approximately 1,500 people in the upper and middle Vaupés River area identify themselves as ethnic Tariana but no longer speak the language.

The Tariana and East Tucano peoples are linguistically exogamous and consider fellow speakers of their languages blood relatives. Languages, like tribal identity, are acquired through patrilineal descent and as such are kept strictly separate from one another, with minimal lexical borrowing occurring among them. Traditionally, Indians in the Vaupés region spoke between three and ten other languages, including their mother's tongue and Spanish and/or Portuguese.

Speakers of Tariana have been switching to the unrelated Tucano language (of the Tucanoan family), which became a lingua franca in the Vaupés region in the late 19th century. Arriving in the region in the 1920s, Salesian missionaries promoted the exclusive use of Tucano among Indians in an effort to convert them. Economic concerns have also led fathers to increasingly leave their families to work for non-Amerindian Brazilians, which has undermined the patrilineal father-child interaction through which Tariana was traditionally acquired. In 1999, efforts were made to teach Tariana as a second language in the secondary school in Iauaretê. Regular classes in Tariana have been offered at the school since 2003.

Research on Tariana, including a grammar book and a Tariana-Portuguese dictionary, has been done by Alexandra Aikhenvald from the La Trobe University, a specialist on the Arawak language family.
