Well, the administrative body of the type of "separation" among the Zaporozhians, and then in Ukraine, and in the Kuban-Rada in its functional meaning "circular management" (democratic) is borrowed through the Poles from the German "Rat", which is from the Old German "radical" and the "pro-Indo-European" meaning "to think" to "/to think"/to think. I mean, "Rhoda" is literally "encouraging". But the funniest thing is that the Slavic equivalent of the same Proto-Indo-European "rei" is "radipati" in the sense of "to take care / care".
