Wenceslaus, Wenceslas, Wenzeslaus and Wenzslaus (and other similar names) are Latinized forms of the Czech name Václav. The other language versions of the name are German: [[Wenzel]], Polish: [[Wacław]], Więcesław, Wieńczysław, Spanish; Castilian: [[Wenceslao]], Portuguese: [[Venceslau]], Russian: [[Vyacheslav (disambiguation)|Vyacheslav]], Croatian: Vjenceslav, Lithuanian: Venckus among others. It is an archaic Polish male given name descending from the Polish word Węzel/Wenzel, Latinised as Wenceslaus spelling for Czech rulers called Vaclav. It is a very old Lechitic word and name also used in other West Slavic languages such as Czech Slavic dithematic name (of two lexemes), derived from the Slavic words veli/vyache/więce/više ("great(er), large(r)"), and slava ("glory, fame"), both very common in Slavic names. It roughly means "greater glory". Latinised name Wenceslaus corresponds to several West Slavic, Lechitic given names, such as Wieceslaw, Wiecejslav, Wieńczysław/Vienceslav, Vjenceslav, Wenzel, Węzel, Wacław/Vaclav and a few more.
