Guató (Guató: go-t͡ʃéuvɨ́ i-ótɨ́) is a language isolate spoken by two of the Guató people of Brazil. It has variously been claimed to be of Macro-Jê or isolate affiliation. Guató is a VSO language, has agglutination, and has ergative alignment.

Classification

Terrence Kaufman (1990) provisionally classified Guató as a branch of the Macro-Jê languages, as did Aryon Rodrigues (1999) and Martins (2011), but no evidence for this was found by Eduardo Ribeiro and Hein van der Voort (2010). Andrey Nikulin (2020) excludes this possibility.

History

Documentation

The Guató language is first documented in a number of wordlists, beginning with François-Louis Laporte, comte de Castelnau's 1851 publication, and followed by others through 1959. The only substantial grammar of Guató was written by Adair Pimentel Palácio and published in 1984.

Language contact

Marcelo Jolkesky (2016) identifies lexical similarities with the Bororo, Tupi, and Karib language families, which, according to him, are due to contact.

Geographical distribution

Today, the Guató mainly reside in Guató Indigenous Territory and Baía dos Guató Indigenous Territory. All residents speak only Portuguese, and the two remaining speakers live elsewhere.

Loukotka (1968) reported that as of 1964, in Mato Grosso do Sul, Brazil, Guató was spoken on the banks of the Paraguay River and up the São Lourenço River, along the Bolivian border. It was also spoken at Uberaba Lake in Santa Cruz Department, Bolivia.

Phonology

Vowels
