What does this mean? Well, obviously the 6th century invading Sclavi (Slavs or Suavs) who covered, inch by inch, the territory of the Teutonic Suevi (then Suavi) were able to find a few remaining Suevi that taught the Slavs what a proper name was (the Slavic Slavs probably ate their Teutonic teachers after that – the Teutons were, of course, delicious).

Or maybe this is different, Maybe, the medieval Slavs read Caesar’s Commentaries on the Gallic War and said, let’s name our kids after the anti-Roman protagonists? That’s another highly=probably possibility.

But why not give some space to the experts. Here is an entry on Nasua fromthe Reallexikon der germanischen Altertumskunde volume 20. The entry comes from Reinhard Wolters
