CZECH

In no way this one is claimed to be an official etymology. But look at the 'official' one:

"...said to be from the name of an ancestral chief, but perhaps from a source akin to Czech četa "army...".

Period. This is the only available interpretation. Nothing else exists.

Does it mean we have no right to look for new versions? No way. Does it mean we can't have a look from our solid and systemic pankartvelian point of view? NO WAY! Quite contrary: WE ARE OBLIGED to try to explain the word CZECH from Kartvelian point of view. Especially since it's easy:

ჩეხვა (chekhva) - wood-chopping

There's no need to explain how important wood-chopping has been in Czechia throughout its history. It's a quite foresty nation (remember, one of its main forests - Krkonose - bears Kartvelian acorn - krko - as its root).

So, isn't this version better than the 'offical' četa?
