Klaas

Klaas is a Low German and Dutch contracted form of the Greek name Nikolaos, composed of the elements nikē, meaning victory, and laos, meaning people. It has been a common given name in the Netherlands and northern Germany for centuries, closely associated with the folklore figure Sinterklaas, the Dutch Saint Nicholas whose feast on December 5 became a foundational influence on the broader Santa Claus tradition. The name is cognate with Nikolaus, Niklaus, Klaus, and Claes, all of which descend from the same Greek original through various regional adaptations.
