Maco

Wirö (also called Itoto, Jojod, or various forms of Maku, especially Mako-Wirö) is an Indigenous language of Venezuela and Colombia spoken by the Wirö people. Until it was properly documented in 2015, it was attested only by a list of 38 words collected ca. 1900, though even that was enough to show it was closely related to Piaroa. Speakers of the two understand each other, though not reliably, and consider them to be distinct languages.
