Slavs
Slavs are the largest ethno-linguistic group in Europe. Present-day Slavic people are classified into East Slavs (chiefly Belarusians, Russians, Rusyns, and Ukrainians), West Slavs (chiefly Czechs, Kashubs, Moravians, Poles, Silesians, Slovaks and Sorbs), and South Slavs (chiefly Bosniaks, Bulgarians, Croats, Macedonians, Gorani, Pomaks, Montenegrins, Serbs and Slovenes).
Ukrainian Soviet Socialist Republic
The idea of Ukraine as borderland crept in the English language at some point. Therefore, while Ukraine was part of the Soviet Union, Anglophones referred to the Ukrainian SSR as "The Ukraine". However, since the fall of the Soviet Union, the officially recognized name is simply "Ukraine". The definite article may imply that it is a land or general geographic area with unidentified borders.
