Prepositional Phrase - Two Parts

  edgood  —  Grammar Tips
The prepositional phrase consists of two major parts:

1. the preposition 2. the object of the preposition

The object is the noun (or pronoun) attached to the sentence by the preposition. That noun might be a true noun, a noun phrase, or a noun clause. The entire unit then acts in two major ways:

1. as an adjective 2. as an adverb

Let’s look at various types of prepositional phrases. Note especially that various noun forms can serve as the object of the preposition:
Preposition Object Type of Noun Example and Function of Prepositional Phrase
