A prepositional phrase is a modifier that does what?

A prepositional phrase is a modifier that adds information about a noun or pronoun in a sentence. It does this by describing:

* Location: *The cat slept on the couch. *

* Time: *We met at the park in the evening. *

* Direction: *The bird flew over the house. *

* Means: *The painter created the mural with a brush. *

* Purpose: *She went to the store for milk. *

* Possession: *The book on the table is mine. *

Essentially, prepositional phrases act like little details that tell us more about the noun or pronoun they're attached to.
