What does German mean?

Some scholars say that "Germanus" (formerly written in Latin as "germanvs") derives from "germ", "to sow, to disseminate", "unfolding", with a conotation of spread but become and kept "relative" or "akin", this referring to the arrival of "barbarous" (but... accepted...) tribes to the borders of ancient Roman Empire or something alike. On the other hand, the word "hermanus" in Latin means "brother", and we learn that... ancient Germans constituted a kind of "political friendship" (the "Sacred Roman-German Empire") with ancient Romans. Germans do not use this word for themselves; they are "deutsch" (from "teutsch", from "teutonisch" or people of the Teutons, a mountain range).

It is most likely derived from the Teutonic statesman Arminius, known as Herrman to the Germanic tribes of his origin, who laid the groundwork for the Roman-German relationship.
