IIRC it also means "world".

The whole point was to get past the Cold War and make union between countries. MIR was peace; Americans and Russians working together for all mankind’s scientific progress

Then came politics.

Why yes, the name Frederick literally comes from the Germanic words frid (peace) and ric (ruler)

It's a lot better than most such maps, but still, there's way too many languages missing in my opinion :)

I speak both languages fluently but I never noticed, lol

"Fred og ro" in Danish

Short for Fredrick, and Rik in Norwegian means rich. So peace, but only if you're rich.

F R E D

In serbian "spokojno" means peaceful as in quiet. Other variations are of death though, "pokojnik" is a dead person.

In russian it means same. I wonder of polish have second word, because pokoy(pokój) is another kind of peace in russian.

Pokój is also Slavic. In Russian related word means something closer to "calmness" and sometimes has overlapping meaning with English "peace". Like "peace" in "peace and quite" for example will be translated with "pokoj", while "mir" in the sense of "peace" means only the opposite of "war".

I assume colors show the original meaning of the word, not the language family.

Edit: whoops, missed your first first question. Yes, fred et al come from Proto-Germanic frithuz, which is constructed from frijaz (free) plus noun suffix -thus.

Well as for the ~~first~~ second one, language families tend to have different roots for the same thing, of which different ones will become preferred in different regions. Both of these words actually work in both Russian and Polish, it is just that one of them is archaic.

As for the ~~second~~ third one, I don't think they're supposed to be the same colour. As far as I know, they are unrelated.

For your ~~third~~ fourth question, no clue. I might look into it someday.

Of course the English have the longest spelling. Why write "paz" or "pau" or "pís" when you can add two more letters? Even French did not fuck it up as much.
