Easy one; Ukraine.

You probably know it already

You don't have to be a slavist to know

I’m seeing if you do, though.

Ukraine is an anglophied version of Ukrajina which means "border land"

Literally meaning in the border land

There you go.

Krajina means borderland but Kraj means land but in polish it's country

Uh, ~~Swedistan~~ Sweden.

In swedish it's sverige

Wait hold on

I only specialise in slavic places

Maybe I can pull out a slavic meaning

That’s alright.

Hold on

S(lo)venska

They did speak roughly the same vandal language

and again the slavic -ska thing

Check this out;

Jeg kopjeter en stol i paris (norwegian)
Jaz sem kupil en stol v parizu (slovene)

Remarkable isn't it

Damn.

yeah

That’s more similar than I’d ever think Swedish and Slovenian would be.

Or swedish;

Jag kopjer en stol i Paris

Moving on,

Belarus, then Russia

Oh

White russia

Probably because of the snow

Russia?

Means "land of the red haired people"

Rossi meaning red

Rossia

Russia

Okay, Bulgaria

Actually the russians still call themselfs "Rossia"

Bulgar-land

Want the origin of bulgar itself orrr

Nah, I already know.
