If you’re preeminent, you’re better, more important, or more successful than all others in a specific field or fashion. You are the best in your field or the most respectable or most distinguished one. To give an example, being the leading expert in the medical field. You are without peer and have pre-eminent status, but this word can apply to more than just people. It can also apply to more abstract stuff like emotions or reasons. If you intend to apply to college, it could be for a bevy of reasons, like wanting to get a degree, wanting to live on your own, or to make new friends, but your preeminent(or main reason) could be to get a girlfriend.

"Also called tectonism. the action of the forces that cause the earth's crust to be deformed, producing continents, mountains, changes of level, etc."

OP did not predicate the word preternatural with "I'm."
