Prepositional Phrase
A Phrase is a group of related words that does not have a Subject and a Verb. One very important and widely used type of Phrase is called a Prepositional Phrase. A Prepositional Phrase provides support for the Subject and the Verb in the sentence, just like Support Sentences give support for the Thesis Statement (see Chapter … page …) in the essay. A Prepositional Phrase always begins with a Preposition and ends with a Noun. Often there is an Adjective in the middle! Here are some examples: Prepositio n on
Adjective
Noun
the
coast
in
college
to
the
game
over
a big, green
Car
The main purpose of a Prepositional Phrase is for support – to let you know location – where the Topic and Main Idea of the sentence (the Subject and Verb) happened. Here’s a list of Prepositions (the most common are in bold type): across below
after beside

of

One of the most useful (but also confusing) parts of Prepositional Phrases is that they can come anywhere in the sentence! They can come at the beginning
before the Subject; they can come at the end; and they can even come between the Subject and the Verb! •
Example with a prepositional phrase at the beginning of the sentence: “(At college), the girl studied.
•
Example with a prepositional phrase in the end of the sentence: “The girl studied (at college).”
•
Example with a prepositional phrase between the Subject and the Verb: “The girl (with the sandals) studied.
•
You can even have lots of Prepositional Phrases in one sentence: “(At college), the girl (with the sandals) studied (on a bench) (in the sun).”
Prepositional phrases can be a lot of things, but they cannot be the Subject! Subject
Prepositional Phrase
Verb
The buildings
of New York
are
skyscrapers.
In the above sentence, New York is not a “skyscraper”; “the buildings are “skyscrapers,” so “buildings” is the Subject, not “New York”!
New York City skyline
Important Comma rule with Prepositional Phrases
There are just a couple comma rules you’ll need to know when using Prepositional Phrases: 1. Use a comma after a Prepositional Phrase that begins the sentence.
•
Comma! (In the early morning light), I saw the Rocky Mountains.
2. Do not use a comma if the Prepositional Phrase is not at the beginning of sentence!
•
no comma! I saw the Rocky Mountains (in the early morning light).
•
no comma! I saw (in the early morning light) the Rocky Mountains.
Here’s an important point: If you don’t have a Preposition, you can’t have a Prepositional Phrase! •
Example: I returned the book.” (“The book”) cannot be a Prepositional Phrase because “the” is not on the list of Prepositions.
•
Example: I returned the book (to the library). (“To the library”) is a Prepositional Phrase because to is a Preposition, and (“to the library”) tells where you returned the book.
The strange case of the word “to”: As you identify Prepositional Phrases, the word “to” can be tricky. That’s because “to” can either be part of a Prepositional Phrase or part of a Verb! Here are some examples: •
When “to” comes before a Verb, you do not have a Prepositional Phrase.
For example: “I like to swim.” Since “swim” is an Action Verb, (to swim) cannot be a Preposition!
For example: “To be or not to be: that is the question.” Since “be” is a Linking Verb, (to be) cannot be a Preposition!
•
It’s only when “to” comes before a Noun, that you can have a Prepositional Phrase.
For example: “I like to swim (to the shore). Since “Shore” is a Noun, and since “to” comes before “shore,” the word group (“to the shore”) is a Prepositional Phrase.
