Basileus (Greek: βασιλεύς) is a Greek term and title that has signified various types of monarchs in history. [...]The following clue is worth considering, in my opinion:
The etymology of basileus is unclear.
Source: Das magusanische Europa, oder: Phönizier in den Innen-Landen des europäischen Westens bis zur Weser und Werra: Skythisches Einvolk und Einsprache in Hoch- und Vorder-Asien, Nord-Africa, spaeter Ost- und West-Europa, Volume 4 (1834), Wilhelm Gottlieb Levin von Donop (p.197: list of "Semitische und Gaalische Herleitungen")
Not all suggested etymologies in this list are convincing, but this one is, to me:
Bas-Luis = Vorstand des Volks (German) = president/ leader of the people
LJUD or LJVD in OLB, see earlier post about HÉRLJUD - Heruli.
hljóð - icelandic
ljuda - swedish
lyd - norse, danish
lui, lieden - dutch
leute - german
(note the name LJUDPOLD - Luitpold - Leopold)
The Online Etymology Dictionary has:
boss - "overseer," (...) from Dutch baas "a master," Middle Dutch baes, of obscure origin.And on the dutch Etymologiebank it says (translated):
baas - leader, head of something (...) of unknown origin (...)Are established etymologists paid to play dumb?
There are no related words in other Indo-European languages.
It is probably a word from a non-Indo-European substrate.
Derived from Dutch are:
boss, base, bass - english
bas, baß, baas - german
bas - danish, swedish, norse
Basileus = luisbaas (dutch) = LJU(D)S.BÁS (fryas)
Here are the OLB fragments with BÁS (master, boss, etc.), four of which referring to the Mágí (fragments 4, 5, 6, 7):
