As i already said if one would name one region of Europe where a language of the Slavic family is spoken it would be Eastern Europe
Not only Eastern Europe:
en.wikipedia.org/wiki/Slavic_peoples
The Slavic people are an Indo-European ethnic-linguistic group living in Central Europe, Eastern Europe, Southeast Europe, North Asia and Central Asia, who speak the Indo-European Slavic languages
en.wikipedia.org/wiki/File:Slavic_europe.svg
since geographically it makes the most sense.
What do you mean? To you Slavic = The East? And any country which isn't Slavic isn't Eastern Europe?
Oh come on, i will certainly not debate if Russian is a Slavic language.
Erm... I won't either, that's not why I've put this quote on here o_O I've quoted this fragment because in the article on Russian language Wiki again calls Polish Central European language.
I will go into the details of your questions tomorrow.
OK.
