I have no idea why you’re addressing that post to me. Serbian and Croatian are essentially the same language except for alphabet and some vocabulary. I have known that for decades.
“Like writing English in Cyrillic”, y’know?
Heh, heh, nice transliteration. But the spoken language is “Serbo-Croatian” & it is written in two alphabets.
Now...the real gulf is between Orthodox Serbs who tend to be pro-Russian, and Catholic Croatians & Slovenians who are more Western oriented.
