Meaning and origin of Klaus
Klaus is a German and Greek name that means “German short form of Nikolaus, victory”.
Klaus is the German short form of Nikolaus, the German form of Nicholas, from the Greek Nikolaos, victory of the people. Saint Nicholas, the fourth-century bishop of Myra, is known in German as Sankt Nikolaus, and his figure contributed to Santa Claus, whose name comes from the Dutch Sinterklaas. Klaus is common in Germany, Denmark and Scandinavia. It is said KLOWS, rhyming with house. Nicholas, Niklaus and Claus are related forms. Klaus Mann, the German novelist and son of Thomas Mann, is a notable bearer.
