Ready for another poorly edited journey into a language lumper's dreamland? Well, stay tuned because you’re sure to love today’s video.

In this video, we discuss how Colarusso took his knowledge of the Northwest Caucasian languages and managed to piece together a macrolanguage family hypothesis, which posits a potential relationship between Indo-European and the NWC languages, suggesting they may have shared a common ancestor termed 'proto-Pontic'- which he (partially) reconstructs. Despite initial skepticism, Colarusso's work reveals compelling parallels between the phonological systems, grammatical elements, and lexical correspondences of these language families. There is even a nice parallel from IE myth.

Of course, there are many weaknesses – some of the cognates seem far-fetched and minimal in number, and many of the grammatical similarities aren’t unique to NWC. Interesting, though, is how NWC might have influenced PIE phonology with regard to laryngeals and the stop system.
So is the Proto-Pontic hypothesis any better than say Blevins’ Proto-Indo-European Euskarian?

Maybe not, BUT!

Colarusso's hypothesis, I believe, was the catalyst for discussions within the linguistic community, drawing attention to the complex interplay between language families in the Caucasus region – particularly with regard to the proposed Indo-Uralic hypothesis. He often isn’t given enough credit for his work – and his proposals do seem to solve some of the nagging questions regarding the earliest forms of PIE and actually with the Indo-Uralic hypothesis too. Of course, he wasn’t the first person to point out similarities between the two language families, but he was the first to put together the real groundwork of correspondences.

We also explore the perspectives of linguists such as Eric Hamp and Allan Bomhard, the latter of the two offers alternative interpretations and expands upon Colarusso's ideas – and again doesn’t seem to get much credit for his work despite that fact that many scholars now seem to accept some form of Caucasian influence in Indo-European.

Part 2 of this series will explore the idea of Northwest Caucasian influence on Indo-European rather as a substrate – and not a sibling. Interesting stuff so stay tuned!

Also, for those who are interested, the very first person to notice similarities between PIE and the Caucasian languages was Uhlenbeck here:
