Logically. Polish and Serbian are kin languages. But I was specific. In Serbian Krajina is bordering land of some realm.
Yes, "genius", all Slavic languages are kin lanuages and so it happens that we have the same or similar words in our vocabulary meaning the same or similar things. Name "Ukraina" comes from Old East Slavic (called also Old Russian - "staroruski") language, not from Serbian. Serbs can't claim ownership over words that exist also in other Slavic languages lol 🤦
In that time when Serbians had their two states in what is now Ukraine
Yes, thanks to you I just googled it and found out that Serbs served as
colonizers for the RuSSian empire in the 18th century in parts of Ukraine, which just makes me more sick of you and RuSSia. 🤮 But this doesn't have anything to do with the term "Ukraina" coming into being, because this name was recorded already in the 12th century.
