Sometimes we us two or three prepositional phrases in a row. Each prepositional phrase begins with a preposition and ends with an object of the preposition.
Here is an example of multiple prepositional phrases in one sentence:
That book is on the shelf in our classroom.
This sentence has two prepositional phrases: on the shelf and in our classroom.
Notice the prepositions on and in. The objects of the preposition are shelf and classroom.
Here are more sentences with multiple prepositional phrases:
We drove over the bridge onto the highway.
Two prepositional phrases: over the bridge, onto the highway.
My little brother ran down the stairs into the basement.
Two prepositional phrases: down the stairs, into the basement
Janet gave the box with my name on it to her mother.
Three prepositional phrases: with my name, on it, to her mother
It’s good to remember that you can use multiple prepositional phrases all in a row inside a sentence. Each prepositional phrase will begin with a preposition and end with an object of the preposition.
