They wouldn't be distinguishable from inherited /k/ (> /c^/)
vs. /kW/. Note that I'm using supposed parallel loans to corroborate
my claim (nothing inherent in the root itself). They are not always
available. Note also Greek kukl-, not the regular reflex of PIE /kW/.
That variation also points towards a loan. Also I would like to see
Witzel's Para-Munda ka- prefix somehow involved in this. Assuming
borrowing from Para-Munda into IA and thence cadraig'ing into Western
PIE would take care of that.
Also, the supposed existence in PIE of an unpalatalized velar
series /k/ etc, rests on its reflex /ka-/ in Latin. But what if they
are all borrowed Para-Munda stuff (ka- prefix)?
Note also Witzel's remark that the k-/nothing- alternation may
originate in Para-Munda. But that takes us straight into basic IE (as
he is aware of). Example Vedic kapi, Germanic apa "monkey".
