The term "most confederated" does not have a specific etymology as it is an adjective phrase made up of two separate words: "most" and "confederated".
The word "most" is an intensifier used to indicate the highest degree of something. It comes from the Old English word "mǣst" meaning "greatest" or "highest", which is derived from the Proto-Germanic word "*maistaz".
On the other hand, "confederated" is the past participle form of the verb "confederate". It is used to describe an alliance or union between individuals, groups, or states with a common purpose or goal. "Confederate" comes from the Latin word "confoederatus", which is a combination of "con-" (meaning "together") and "foedus" (meaning "treaty" or "league").
