Language Contact and Language Blend: Kumandene Tariana of Northwest Amazonia

The Vaupés River Basin in northwest Amazonia is a well-established linguistic area characterized by obligatory multilingualism and exogamy based on linguistic allegiance. The core members of the area who take part in the multilingual marriage network are speakers of East Tucanoan languages and of one Arawak language, Tariana. The impact of East Tucanoan influence on Tariana is recognizable through structural diffusion. Two dialects of Tariana are currently spoken. Wamiarikune Tariana (W-Tariana), with a few speakers in the middle Vaupés area, is highly endangered; it is under strong pressure from Tucano. Kumandene Tariana (K-Tariana), also endangered, is spoken in the community of Santa Terezinha on the Iauarí River (tributary of the Lower Vaupés). The K-Tariana moved to their present location from Iauaretê on the middle Vaupés two generations ago, escaping pressure from Catholic missionaries. The K-Tariana intermarry with the Baniwa Hohôdene, speakers of a closely related language, now the major language in their village. Over the past 50 years, speakers of K-Tariana have acquired numerous Baniwa features. This can be seen through comparison with older sources on this dialect. At present, the degree of Baniwa impact on Kumandene Tariana varies, depending on the speaker and on the audience. The result is a curious language blend. This paper discusses the status of K-Tariana in the context of other blended, or “merged,” languages.
