The word Teutonic means Germanic. It is a term used to describe Germanic tribes, people or languages. The word originates from the Latin name for a tribe whom the Romans believed to be of Germanic ancestry. They were called as Teutone and the term Teutonic originated from this word. The Romans not only considered them as of Germanic origin they also started using this term as a synonym for Germanic or Germanicus.
Today many are of the opinion that the teutones or the Teutonic people were not Germanic at all and on the other hand they were a Celtic tribe because the word teutone also meant "the people" in the Celtic language. But the Germans already used this term for Germanic by the 900 and later on the term tiutisch was modified into teutonic. William Z. Ripley used this term to describe and designate one of the three European races known as the Nordic races.
