Originally “cyborg” came from English cybernetic organism. In Latin that would of course be organismus cyberneticus. Given the mouthful of that, it is no wonder that people tend to simply use the undeclinable “cyborg” instead. But is there any reputed word used for “cyborg” in Latin that is shorter than that? The same way “robot” has robotum and “car” has autocinetum.
Thanks in advance for the answer!
EDIT: Just to make clear what a cyborg is (which would probably help the answers). A cyborg is a being that is partially organic and partially machine. This is different from an android that is just a machine that mimics the human form.
