Prepositions show where things are, like places, people, and time.
The classic definition is :
"What a plane can do to a cloud."
In a cloud, by a cloud, near a cloud, etc.
This shows where a plane can be compared to a cloud. But remember, it can be in many other places too. To describe locations, you can use one word (like "above") or a group of words (such as "on top of"). Words like "below," "behind," "before," "beside," and "beneath" have the stress on the second part, and the first part is made shorter (like "b'low," "b'hind," "b'fore," "b'side," "b'neath").
