The Vagoths were a Germanish folk said by Jordanes to have been living in Scandza. Thoughts about their true selfsameness have linked them with the Geats of Vikbolandet and with the Gotlanders, both in latterday Sweden. They have also been linked with the two stows named by Jordanes, the vastissimus lacus ("widest law") and the Vagi fluvens ("Vagi ea"). Karl Zeuss thought Vagoth to be a misstaffing of Vagos and linked them to the Vagar who later atewed in the Dovrefjell of Norway. Karl Müllenhoff, too, thought the name a forbraiding. He put forward *Augothi or *Avigothi (Norse *Eygutar) and put them in Yewland.
Following the Lettowish speechloresman Kazimieras Būga, the name of the Thetchlanders and Thetchland in the Lettowish and Lettish tungs (Lettowish vókietis, Vókia, Vokietija and Lettish vācietis, Vācija) comes from the name of the Vagoths (*Vāk(ia) + -goth). From the Baltish tungs stem Finnish roots Vuoja, Vuojo and Estish Oju, Oja in their name for Gotland: Vuojola, Vuojonmaa, Vuojanmaa, Ojumaa, Ojamaa (maa = "land"). The Lettish speechloresman Konstantīns Karulis, known for his Wordbook of Lettish Wordstear (1992), sees another wordmore, alike to the one in the Windish word for the Thetchlanders, eftbuilt as Orwindish *němьcь ("a dumb leed, somebody who cannot speak [Windish]"). That is to say, the Baltish name for Thetchlanders may roughly mean "neighbors who speak a tung which cannot be understood", and thus may stem from the Or-Indeuropish root *wekʷ- ("to speak, to lide").
