Contracted form of an older Czech name Veceslav, derived from the Slavic elements vęťĭjĭ "more, greater" and slava "glory". Saint Václav (known as Wenceslas or Wenceslaus in English) was a 10th-century Duke of Bohemia murdered by his brother. He is the patron saint of the Czech Republic. This was also the name of several Bohemian kings.
