Over means above something or covering it, or it can mean more than a certain amount, or that something has finished.
From Old English *ofer* meaning “above, beyond, across,” related to German *über*. Its many senses grew from the basic idea of moving or being ‘beyond’ a point.
This tiny word does a huge amount of work: physical space (over your head), amount (over 50), time (over the years), and even completion (it’s over). English loves reusing small words to build big ideas.
