I think I'll use "exter" for the 4D term for "higher dimension" since it sounds nice and isn't actually a word outside of like. a random car model that no one cares about.
the 4D equivalent of "up" or "height".
and for the 4D equivalent of "down" or "lower"
I'll use "ineter"
since exter sounds like dexter so may as well make the opposite sound sort of like sinister.
feel free to use, and feel free to suggest variations, since we have multiple words referring to up and down.
