Nis

Nis is a Danish short form of Niels, itself the Scandinavian contracted form of Nicholas, which derives from the ancient Greek name Nikolaos, composed of the elements nike, meaning victory, and laos, meaning people. The name has long been embedded in Danish folk tradition, where Nis is the name of the nisse, a household spirit of Norse and Scandinavian mythology associated with the protection of farms and families. Related forms include Niels, Nils, and the wider European variants Nicholas and Klaus.
