Toba or Namqom is a Guaykuruan language spoken by the Toba Indians in
Argentina, Bolivia and Paraguay. The majority of these speakers (25,000) are found in the northeastern Argentine provinces of Chaco and Formosa. About 1,000 more are scattered through the adjacent Gran Chaco region of Bolivia and Paraguay. Aside from this central zone, recent immigration has led to the settlement of about 1,000 speakers in the Gran Buenos Aires area and about the same number in several cities in the province of Santa Fe. The Toba are the largest indigenous group in the northeastern region of Argentina, and the ones with the greatest influence among the Indian and the non-Indian regional population. Toba is closely related to four other languages of the Guaykuruan family: Mocovi, Pilaga, Kadiweu (Mbaya), and Abipon (extinct). This work will provide a linguistic overview of the fundamental features of the language. Toba is an OV language, but other patterns of word order are possible. A discussion of important syntactic and semantic properties of the agreement system will be provided. The sketch will also include a detailed description of the phonology and morphology as well as several short texts with interlinear translations and a glossary.
