This is the Czech equivalent of the Proto-Slavic name *Vęceslav, which has its variant in Ukrainian tradition—V'yacheslav. The name is composed of the Polish word "więcej," meaning 'more,' and the noun "-slav." The original meaning of the name V'yacheslav was a wish for "More glory!"In Old Czech, the name appeared as Veceslav. The variant Vацлав became known to Ukrainians, likely through the Poles. The name Vацлав was canonized by the Catholic Church rather than the Orthodox Church, which is why in Ukraine, just as in Poland, the name Vацлав became established in its Czech form.Over time, influenced by the Polish pronunciation of the name Wieńcesław and the Latin Vincenti (which comes from the Latin "vincens," meaning 'winning'), a mistaken association arose between these two different names and the Slavic word "вінець" (meaning 'wreath'). This led to the emergence of the literary variant of the name Vincislav.The name Vацлав is also known among the Hutsuls and was used in Podillya and Polissia. For example, in 1635, a nobleman named Vацлав Shcherbyna was mentioned. In the city of Lutsk, the name Vацлав was also used during the interwar period.
