Koropó language

Koropó (Coropó) is an extinct language of eastern Brazil. It has been variously classified as a Maxakalían or a Purian language.

Classification
Although Silva Neto (2007) had assumed Koropó to be a Purian language, Nikulin (2020) classifies Koropó as Macro-Jê (Maxakalían branch).

Documentation
Koropó is attested by two word lists collected by German explorers in the early 1800s:
 * Eschwege (2002: 122-127), 127 words collected in 1815
 * Schott (1822, pp. 48-51), 55 words collected in 1818

Distribution
In the 18th century, Koropó speakers lived with Coroado Puri speakers along the Pomba River in Minas Gerais.
