Noun as Object of Preposition

What is an Object of Preposition?

Before answering the question, it is important to know the role of prepositions.


So what are prepositions?

Prepositions are used to connect the parts of a sentence, expressing relationships. To be specific, prepositions are used to create prepositional phrases.


What are prepositional phrases?


Prepositional phrases consist of a preposition and its object—often a noun or a pronoun. When a noun is part of a prepositional phrase, it is called the object of preposition. 


To answer the question, an object of preposition is a noun or pronoun referred to by its preposition. And it often appears after the preposition.


examples:


"The laptop is on the table."

—on is a preposition of place, and it expresses the relationship between the laptop and the table—that the laptop is on the table's surface. The table is the object of the preposition here. 


"My phone is in the bag."

—in is also a preposition of place. The same with the first example, the preposition expresses the relationship between the phone and the bag—that the phone is inside the bag. The bag is the object of preposition here since it is the one being modified. 


"Lisa is at work."

—at is also a preposition of place, and it expresses the relationship between Lisa and the school—that Lisa is at the moment at school. The school is the object of the preposition, as usual.



Notice that in the first and second examples, before the objects, there comes the definite article "the". It often happens, especially if the noun needs to be modified or described. There will be times that "a/an" or "demonstrative pronouns" will be used before the objects.
