The word Fuhrer is synonymous with Hitler. But what does the word mean? Generally it means 'leader' and this is the translation most people use. But it also related to the words for travel and companion, as we will see.
It was the German medieval chronicler Adam von Bremen who wrote - Wodan id est furor! Wodan, he who is Fury! If we look at the word for fury -Furor- we can see how it derives from the same root as Fuhrer. The Fuhrer is the rider, who leads the Wild Hunt! The Son of Wotan who woke Germany to a twelve year Reich (12 being the sacred number in Yule rites when Woden leds the Wild Hunt over Germania).
There are many Germanic words which cognate with 'Fuhrer'. One old English word is 'Fere' which came from the proto Germanic word 'for-ja'. This was a 'companion'. This word evolved into the Germanic word 'forjan', itself becoming 'fuoren' then 'fuhrer'. The word 'faran' meant 'one who travels' or 'to set forth'. In the Dutch language this became 'Fare', as well as in English, though not widely used any more.
These examples are from the Germanic world. But the idea of the 'fuhrer' is of course pan-Aryan. In the ancient Aryan world we find more examples of the word Fuhrer. In Aryan Persia (Iran) the Zoroastrian symbol of the Faravahar was also know as the furōhar or frawahr.
