Cumana language
Cumana is a possibly extinct Chapacuran language. Various names ascribed to the language in Campbell are Torá, Toraz, and Cautario, the last perhaps after the local river, and Abitana-Kumaná.
In addition, there is a Chapacuran language called Kujubim, which may still be spoken. The endonym, Kaw To Yo , may be the source of the river and language name Cautario. Sources which list one do not list the other, so these may be the same language.
