Which prefix refers to something that is "over" or "above"?

The prefix that refers to something that is "over" or "above" is indeed "super-." This prefix originates from Latin, where it means "above," "over," or "beyond." It is commonly used in various English words to indicate a higher level, superiority, or an extended degree of a characteristic.

For instance, in the word "superhuman," it implies abilities or qualities that exceed normal human capabilities. This prefix effectively conveys the sense of enhancement or elevation in comparison to a standard measure.

In contrast, "tachy-" usually denotes speed, often meaning fast or swift, while "trans-" implies crossing over or going beyond, such as in "transport." Lastly, "ultra-" suggests an extreme or excessive degree but doesn't specifically denote "over" or "above" in the same direct manner as "super-." Each of these prefixes has its own specific meaning, which distinguishes them from "super-."
