Niggle: "su" from "sudo" is for substitute/switch user in the su command, not "super" at all. By default the user being switched to in su is root/uid:0.

There's no such thing as "Super User" in context usage.

The historical and original meaning was superuser do and superuser is absolutely a thing in UNIX.

See here from the guy who invented it:

and here

Also the "su" command originally stood for "superuser":

"su allows one to become the super—user, who has all sorts of marvelous powers"
