 Irminonic or Elbe Germanic is also therefore a term for one of the unattested dialect groups ancestral to the West Germanic language family, especially the High German languages, which include modern Standard German.The name Irminones or Hermiones comes from Tacitus's "Germania" (AD 98), where he categorized them as one of the tribes descended from Mannus, and noted that they lived in the interior of Germany.Other Germanic groups of tribes were the Ingvaeones, living on the coast, and Istvaeones, who accounted for the rest.
