Ka--- a substrate

Is this just a red herring.

Khaldiki
Cholchis
Khaldu (Uruartu's name for itself)

Are we getting close to the Pre-Etruscan substrate here?

Also consider

Kaska
Khatti
Hurri
Kassite
Kuti/Guti
Ka-shushtar (Elamite name for itself)

or to be completely anachronistic what about ---

Chaldean?

Well folks? Any takers?
