Sigismund

Sigismund (variants: Sigmund, Siegmund) is a German proper name, meaning "protection through victory", from Old High German sigu "victory" + munt "hand, protection". Tacitus Latinises it Segimundus. It looks like there is an older form of the High German word "Sieg" (victory): sigis, obviously Gothic and an inferred Germanic form, and there is a younger form: sigi, which is Old Saxon or Old High German sigu (both from about 9th century). A 5th century Prince of Burgundy was known both as Sigismund and Sigimund (see Ernst Förstemann, Altdeutsche Personennamen, 1906; Henning Kaufmann, Altdeutsche Personennamen, Ergänzungsband,1968).
