Sapé language
Sapé a.k.a. Kaliana is a nearly extinct language spoken along the Paragua River and Karuna River. In 2008 a few elderly speakers were found. Sape is one of the most poorly attested extant languages in South America, and may be a language isolate. There is, however, no comprehensive linguistic data on the language.Jolkesky notes that there are lexical similarities with the Warao, Chibchan, Puinave-Kak, Jirajara, Tukano, Arutani, and Maku language families due to contact.
Similarities with Chibchan are primarily with the Magdalena subgroup.
