It has been suggested that some apparently Basque names are merely corruptions of late Germanic names. For example, Garsinde leading to Garsean, Gendolf or Centulf to Centule, Aginald or Hunnald to Enneko (in Flanders, and Frisian, still a short form of the first two frank names), Aginard to Aznar, Belasgytta or Wallagotha to Velasquita, Belasgutho to Velasco, Arnoald to Arnau, Theuda to Toda, Theudahilda to Dadildis or Dedadils. While some of them may be so, many of them—Andregoto, Amunna, Aznar(i), Velasco, Garcia, Ximen(o), Enneco—have well explained forms according to consistent linguistic rules and etymologies, as described by linguist Koldo Mitxelena. The oldest Basque medieval names reflected totemic (animal) references, and family links.
