Cueva language
Cueva is a poorly attested and often misclassified extinct indigenous language of Panama. The Cueva people were exterminated between 1510 and 1535 during Spanish colonization. During the 17th and 18th centuries the Kuna repopulated the Cueva area. Classification
Loukotka (1968) mistakenly identified a Kuna vocabulary from the Darién as Cueva, leading to confusion of Cueva with Kuna in subsequent literature (e.g. Greenberg 1987, Whitehead 1999, Ethnologue 2009), with some authors reporting that Cueva was a dialect of or ancestral to the Kuna language (Adelaar & Muysken 2004:62). The Kuna language and culture are very different from the Cueva. Loewen (1963) and Constenla Umaña & Margery Peña (1991) have suggested a connection between Cueva and the Chocoan family. Bibliography
