**Name: Sladiana**
The name Sladiana has its roots in the Serbian language, where it translates to "sweet." This name emerged among Ukrainians, with evidence that it was used in 1950 when a student named Sladiana Kohut was registered in a high school in the city of Šid, Yugoslavia (source: Mudry - Salamon 253).
The name Sladiana is also associated with a newly created feminine name derived from the ethnonym "Slavs." It resonates with the Bulgarian name Slavena (source: Ilchev 454). In Ukraine, there exists the Ukrainian surname Slovian, known since the 18th century, particularly in the city of Uzhhorod and its surroundings (source: Chu Prizv. 523).
Additionally, it is worth noting that there are mentions of the ancient name of the stream Slavyansky, which flows through the village of Luh in the Rakhiv district of Transcarpathia.
