Here's why:
* Prepositions show the relationship between a noun or pronoun and another word in the sentence. They often indicate location, time, or direction.
* Examples: in, on, at, under, over, through, by, with, etc.
* "Covered" is a verb, meaning to place something over something else to hide or protect it.
Example:
* "The blanket covered the sleeping child." ("Covered" is the verb, showing the action of the blanket.)
