[3][4] Jolkesky (2016) notes that there are lexical similarities with the Andaki, Barbakoa, Choko, Duho, Paez, Sape, and Taruma language families due to contact.

Adolfo Constenla Umaña argues that Cueva, the extinct dominant language of Pre-Columbian Panama long assumed to be Chibchan based on a misinterpreted Kuna vocabulary, was actually Chocoan, but there is little evidence.

The Cofán language (Kofán, Kofane, A'i) of Ecuador and Colombia has been erroneously included in Chibchan due to borrowed vocabulary.

On the basis of shared grammatical innovations, Pache (2023) argues that Pech is most closely related to the Arhuacic languages of northern Colombia, forming a Pech-Arhuacic subgroup.
