Cueva people
Cueva was the name assigned by Spanish colonists to various indigenous populations they encountered in Eastern Panama. Although it has been used variously to describe a specific ethnicity, many scholars believe that the peoples who used the Cueva language belonged to multiple ethnolinguistic groups, and that this language was in fact a lingua franca.
