z and y are vertical planes, vertical or orthogonal to each other and to the x axis
generally people refer to y axis as the vertical axis. if z is vertical, then maybe use another word that means vertical but distinguishes it from vertical? altitudinal?
Maybe call whichever isn't the vertical or horizontal the "orthogonal axis" as it's orthogonal to both the other axes. another possibility is "diagonal" if you're not up and down or left and right, then you're diagonal.
If you figure out a good name, maybe patent it. Not that you could make any money off it, but you could claim to have a patent. Abraham Lincoln got a patent on a useless invention. He used to be a patent lawyer, so it was relatively easy for him to get a patent. Former President James A. Garfield discovered a new proof of the pythagorean theorem and gets no real credit from anyone. Wait? How about the pythagorean axis for the missing dimension? We have real, imaginary, irrational, rational, complex, and surreal numbers. Negative, positive, integer numbers. If you find a name for all 3 axes, what about a 4th axis, hard to graph but what would it be called? or the 5th, 6th or nth dimensional axis?

The first citation i found depicted z as the geocentric third axis running up and down. I see your point. Horizontal and vertical both depict a combination of two out of three axis. Z+y = virtical plain, while x = perpendicular irrelevance Just as Z+x = virtical plain, and y = perpendicular irrelevance X+y = horizontal plain, and z = perpendicular irrelevanc. But the same doesnt follow. There's no other axis for either x or y to align themselves as horizontal. Not in 3d euclidean space. A forth spatial dimension seems interesting at this point. Euclidean geometry did leave open the possibility of 4 spatial euclidean space. What would horizontal really mean if it wasnt geocentric. Whats more geocentric than a better connection to whatever causes bent space and the force of gravity? I dont see a concept of a fifth spacial dimensions. I only see that the forth would be bent enough at some point you could eventually call it anything you wanted and it would only fart about it if you were lucky. Btw, did you know i found a black hole and everyone can see it every night? What would a black hole look like? Something from an old disney movie a swirling blah blah? Or maybe it would look like a terminal mass sphearoid from a recent interstellar movie meant to cement in your mind the possibility of terminal mass atmosphear so climatologist funding leaches dont have to admit the expanding atmosphear to anyone on their carbon dioxide scare ride. None of the above it would look exactly as it looks right now. See all that black space inbetween all the stars in every direction you could possibly look in? Its a bit anti climactic but it was right there the whole time. It was everywhere and no where. Not only is it completely obscured in every direction by an infinite mass but it's also infinitely far away as well. We're for any rational measurement, smack dab in the middle of a black hole already. A black hole would only look like it was all the way around you and it and everything else is the only thing you can see. (:05/27/21
