>>17849265>What's "germanic"?>Germ which means Brother/Sibling and is present in greek name Hermes (god associated with sign of gemini aka siblings)The Tuatha de Danann which Njordr was from, was one of the seaborne branches of the Yamnaya which the greek and Romans recognized as, as you so ineptly said,- Gemini.
The land-based Yamnaya and Sea-based Yamnaya are the dictotomy seen with Zeus vs Poseidon, Danava, Daevas Daitya... etc. The norse parallell the particular trinity of the Danava, Daeva & Daitya with their 3 brothers Odin, Vili & Vé.
I do agree with the general sentiment that "German" is a non-term though, as it was the Seaking Scandinavians of the times around Caesar that caused the formation of what the Romans would come to refer to as "German".
It was specifically the Scandi part of the Celto-Roman-Steppe muttsof geographical Germany that they intended to apply the term "German" to, and not the Celtic or Steppe parts.
tldr;
"German" was originally a term coined by Yamnaboo Romans to acknowledge the DANITE heritage of Scandi's as a way to cope and explain away the reason why they could not conquer Denmark.
