 The meaning of the second part of this name form is unclear, but it has for example been interpreted as a Germanic diminutive.Uncertain and disputed is the association of the Rugii with the name of the isle of Rügen and the tribe of the Rugini.Though some scholars suggested that the Rugii passed their name to the isle of Rügen in modern Northeast Germany, other scholars presented alternative hypotheses of Rügen's etymology associating the name to the mediaeval Rani (Rujani) tribe.
