Het peoples

Het is the term used by Thomas Falkner, an English Jesuit, at the end of the 18th century for various nomadic groups from the Argentine Pampas [es] and Patagonia, including the so-called indigenous Pampas [es] and northern Tehuelches, but excluding the Mapuche (speakers of Mapudungun).

Falkner subdivided the Het into the Chechehet, the Diuihet or Didiuhet, and the Taluhet. The easternmost Didiuhet, near modern Buenos Aires and influenced by the Guarani, were called the Querandí. It is not clear if these peoples were related linguistically or only culturally.

The Het were neighbored on the north by the Chaná, on the northwest and west by the Mapuche, and on the south by the Puelche.

Faulkner in the middle-to-late 1700s had listed few ethnic groups in the northeastern pampas region that were not Araucanian:

In 1922, Robert Lehmann-Nitsche noted the common "het" in the demonyms and proposed the "Het" language family with multiple members, including Chechehet, Querandí, and Taluhet, although later reduced the family himself to just Chechehet. This idea was later picked up by Loukotka and Mason, but strongly opposed by Antonio Tovar and José Pedro Viegas-Barros [es]. Modern researchers consider the Chechehet language to be another name for Gününa Küne. In accordance with this theory, Glottolog combines linguistic materials for Chechehet with Puelche.

Viegas-Barros, based on the work of Rodolfo Casamiquela, states that the Het languages are in fact "ghost languages" that never existed, the language name arising from problems of interpretation.

The supposed linguistic similarities between languages of different tribes, grouped by Falkner together as "Hets", are highly disputable.^{[citation needed]}

According to Lyle Campbell, the languages are equivalent to Gününa Küne. Campbell (2024) declares Loukotka's findings as stemming form a confusion with a long history".
