what even is a hyperpotamian. is it when pots make you hyper
You know, I actually explained it a couple of times. I got an ask about it way back, I can find it in a moment - it's here. But, I suppose I can just explain it again.
It's basically my way to translate the Hebrew word עברי - meaning Hebrew - to Greek, through certain interpretations. You see, a common explanation on why Avraham was called "ha‘Ivri" is that he came from the other side (Me‘ever) of the river, likely the Euphrates. So I combined the Greek words Hyper, which means over, and Potamos, which means river. Technically I did it with how they're pronounced in Modern English, because I don't actually know Greek, but from what I know these are legitimate Greek (or ancient Greek) words. The latter appears in words like Mesopotamia or Hippopotamus. So Hyperpotamian is supposed to mean "one who came from over/beyond the river".
There's a secondary point there, though. Another traditional Jewish interpretation for ha‘Ivri is that Avraham was on one side - עבר - while the entire world was on the other. In this case, this refers to him being a monotheist. But after 7/10... well. Let's just say I felt a bit isolated. So I formed this name as an interesting way to say Hebrew in English.
For the record, that is not Hebrew like the language. I suppose you could use it this way, since the words do come from one another, but Hebrew is also used as an ethnonym for the Jews and related peoples.
Hopefully my explanation didn't stray too much into being confusing. Anyway, in the early days of this blog I considered also building some sort of alternate history world where there's a kingdom of Hyperpotamia. This never went anywhere, but can work in some ways if we take into account that the Persian larger administrative zone that included Syria and the Levant was called פחוות עבר נהרא, which does mean "the Satrapy of Over the River".
