Macro-Puinavean is a hypothetical proposal linking some very poorly attested languages to the Nadahup family.
[8]: 439 Epps (2008)[1] criticizes the Puinave–Nadahup proposal for relying on inaccurate data, having no clear concept of basic vocabulary, and using an unsystematic mix of Nadahup languages in the comparison.
The languages were originally linked simply because they are all called Maku "babble" by Arawakans; that is, because they are spoken by hunter-gatherers.
Other "strikingly similar" pairs, such as Puinave ueyu "day" and Hup uerhó (wæd.hɔ́) "sun", are not particularly convincing, and no regular sound correspondences have been detected.
On other hand, Martins (1999 and 2005) argues that it is possible to relate "eastern Makú" languages with the Nukak-Kakwa group, but he does not find evidence of the relationship with Puinave.
