ルーシ語
A Lithuanian name Žygimantas, meaning "wealth of (military) campaign", from Lithuanian "žygis" "campaign, march" + "manta" "goods, wealth" has been a substitution of the name "Sigismund" in the Lithuanian language, from which it was adopted by the Ruthenian language as Жыгімонт (such are the cases of Sigismund Kestutaitis, Sigismund Korybut, Sigismund I the Old, Sigismund II Augustus). The Polish spelling is Zygmunt, and the Croatian variant is Žigmund.
