Natu

Natu, also recorded as Peagaxinan, was an extinct language of the Natu people of the Alagoas region of eastern Brazil, spoken along the Ipanema River near present-day Porto Real do Colegio. Vocabulary was recorded from two main efforts, Carlos Estevao's 1940 fieldwork as compiled by Pompeu Sobrinho in 1958 and a separate 1963 compilation by Cestmir Loukotka, together preserving upwards of 25 words covering natural elements such as water, fire and earth alongside cultural items such as tobacco, ceremonial pipes and maracas. On this thin evidence, Joseph Greenberg was essentially the only linguist willing to classify the language, tentatively linking it with the neighboring Xoco language, but the connection is not well established and Natu is generally treated as unclassified.
