Here's a breakdown:
* Prepositional phrase: A group of words that starts with a preposition and ends with a noun or pronoun (the object of the preposition).
* Object of the preposition: The noun or pronoun that follows the preposition and receives the action or relation indicated by the preposition.
Example:
* "The cat sat on the mat."
* "on the mat" is the prepositional phrase.
* "mat" is the object of the preposition "on."
Think of it this way:
The preposition acts like a "glue" that connects the object to the rest of the sentence. The object is the "thing" that is being described or located by the preposition.
Here are some other examples:
* "He walked through the door." (Object: door)
* "She smiled at her friend." (Object: friend)
* "I went to the store." (Object: store)
* "The book is under the table." (Object: table)
