This is because if you know that a noun names a person, place, thing, or idea, you also know that a preposition is a word that comes before one noun to show its relationship to another word in the phrase or clause. This shows that a noun can function as an object of the preposition. The noun that comes after the preposition is called the object of the preposition.
