Prepositional phrases outline the relationships between a sentence’s nouns, pronouns, and other supporting words.

What Is a Preposition?

Before we start discussing prepositional phrases, let’s first define what a preposition is. Prepositions are words that show the relationships between words in sentences. They usually come before nouns, pronouns, gerunds, or clauses to show place, location, time, and direction or introduce an object in a sentence. For example:

The cat sat on the table.
My coworker lives near the church.
We drove over the Golden Gate Bridge.
They have been singing as a group since 2019.
I found the key under the table.

On, near, over, since, and under are all prepositions. These words allow readers to visualize where an object is located or when something happened. If you want to know more about prepositions, feel free to check our article 5 Types of Prepositions: An Easy Guide. Now, moving on to our main topic, what is a prepositional phrase?

What Is a Prepositional Phrase?

A prepositional phrase is a group of words composed of a preposition, an object (noun or pronoun), and the word that modifies the object. Prepositional phrases function as information-givers in a sentence. Let’s take this sentence as an example: With a sharp knife in hand, the man freed the dog from its leash.”With” is the preposition, “knife” is the object, and “sharp” is the word that modifies the object. Together as a prepositional phrase, it tells the readers what the man used to free the dog off its leash.

In most cases, writers use a prepositional phrase to modify a verb or a noun.

For example, why say “you went out” when you can say that “you went out to an incredible party?”

She’s scheduled to leavebefore noon.

Then, you have the option to add a modifier.

She’s scheduled to leavea bit before noon.

“A bit” modifies or further describes the time of departure.

How Do You Identify a Prepositional Phrase?

A prepositional phrase starts with a preposition and ends with an object, which could be a noun, pronoun, gerund, or clause. The object at the end of the prepositional phrase is referred to as the object of the preposition.” For you to easily identify a prepositional phrase, you need to know the format or pattern it follows in a sentence. There are two ways to write a prepositional phrase, as illustrated below:

Preposition + Modifier + Object (Noun, Pronoun, Gerund, or Clause)

Preposition + Object (Noun, Pronoun, Gerund, or Clause)

Here are some examples of prepositional phrases following the preposition + modifier + object format:

From my savings
Under the long bridge
Beneath the old oak tree
Through the broken window
Along the busy streets

Now, the following are examples of prepositional phrases written in the preposition + object format:

From grandma
About what you need
Beneath us
Through him
At work

If you can spot any of these two patterns, you’ll be able to identify prepositional phrases easily in any sentence.

To characters show the relationship between prepositions and nouns. On the right is a taller man with a sign around his neck that reads Preposition. To his left is a smaller woman holding his hand. She has a sign around her neck that reads NOUN.
We use prepositions with nouns to emphasize, connect, or clarify ideas.

What Is an Example Of a Prepositional Phrase?

Here are some examples of prepositional phrases in action. We’ll give you a sentence, identify the prepositional phrase, and explain how it works.

The Wicked Witch lives somewhere over the rainbow.

Here, we’re demonstrating the connection between the rainbow and where the Wicked Witch lives.

My magazine fellbehind the couch.

How are the couch and magazine related? One fell behind the other!

Eliza jumpedfor joy.

Why did Eliza jump? “For joy!”

To make things easier, she reserved a roomby the elevator.

“By the elevator” indicates where the room is.

Types Of Prepositional Phrases

There are two types of prepositional phrases, depending on the modifier describing the object: adverbial and adjectival. Adverbial prepositional phrases function as adverbs and answer questions like where, when, how, and why. Adjectival prepositional phrases act as adjectives and answer one of these two questions: What kind of?Which one?

In the succeeding sections, we’ll discuss the major differences and effective usage of these two types of prepositional phrases.

What Is an Adverbial PrepositionalPhrase Example?

Adverbial clauses get their name from the fact that they function as adverbs.

For example, we use adverbial prepositional phrases to show timing or cause and effect. They might tell you when or where something happened. They might also detail how something happened or to what extent.

Adverbial Prepositional Phrases contain a preposition. But, the entire phrase functions as an adverb. This is because the phrase shows when, how, or why something happened.
Because I went to the store early, I was able to get the new video game before it sold out.

In this example, “because I went to the store early” is an adverbial clause. This is because it demonstrates how the action in the second part of the sentence came to be.

“Before it sold out” is also an adverbial phrase because it described when that action took place.

Since Marika left her wallet at home, she had to borrow money for the bus.

Here, “Since Marika left her wallet at home” demonstrates what caused her to have to borrow money.

What Is an Adjectival Prepositional Phrase Example?

On the other hand, an adjective phrase modifies the noun or pronoun that comes immediately before it.

Adjectival Prepositional Phrases contain a preposition. But, the entire phrase functions as an adjective. This is because the complete phrase describes the object it follows.
The manon the islandmade friends with a volleyball.

“On the island” describes the man. The object of the prepositional phrase is the island. What’s more, the phrase itself indicates how the island and the man are connected.

The slice of cakein the pantryis mine.

In this case, the pantry is the object, and the prepositional phrase is describing the link between the cake and its location.

A boy and girl holding hands while pointing in different directions. The girl on the left wants to go somewhere else.
An adjectival phrase modifies the noun or pronoun that comes immediately before it in a sentence.

Prepositions That Begin Prepositional Phrases

Here are some examples of common prepositions that you often see at the start of prepositional phrases. Jump over to our types of prepositions guide to explore a full list of common, simple and complex prepositions.

Common Prepositions

There are also some multi-word prepositions. These contain two or more words that function together to create a complex preposition.

  • According to
  • In spite of
  • Along with
  • On account of

Can You Begin a Sentence With a Prepositional Phrase?

The quick answer to this question is YES. You can begin a sentence with a prepositional phrase. Prepositional phrases appearing at the beginning of sentences are called introductory prepositional phrases. Besides giving additional information, introductory prepositional phrases also help provide a sense of flow to any written work. They make the text less choppy and pleasurable to read. Read the following paragraph:

Since 1985, the coffee shop across the street has served thousands of locals and tourists. It’s a favorite spot for travelers and people who want to grab a quick cup of coffee before starting their busy day. Beside the famous coffee shop, you’ll find the town’s only souvenir store where you can buy all sorts of locally made products.”

The ones underlined in the paragraph above are introductory prepositional phrases. Notice how they provide extra information and help with the flow of the sentences? Now, you also need to pay attention to the placement of your comma when using introductory prepositional phrases.

Comma After a Prepositional Phrase

As a general rule, you can choose to use a comma after a short introductory prepositional phrase or forego using one. By “short,” we mean prepositional phrases that are no longer than four words. Prepositional phrases longer than four words automatically get a comma after them. For example:

On Monday the recruit will start his training.
On Monday, the recruit will start his training.
Near the town there’s an abandoned mine.
Near the town, there’s an abandoned mine.
During the wee hours of the morning he packed his bags and left his home.
During the wee hours of the morning, he packed his bags and left his home.
Beneath the busy streets of Paris you’ll find the city’s centuries-old catacombs.
Beneath the busy streets of Paris, you’ll find the city’s centuries-old catacombs.

Is It a Preposition or an Adverb?

Some words can function as prepositions and as adverbs. You can easily figure out whether a word is acting as a preposition or an adverb by looking for the object.

Preposition or Adverb?

  • If your word refers to an object, it’s probably a preposition.
  • If your word doesn’t refer to an object, or there is no object in sight, it’s probably an adverb.
Adverb:She ran up.
Preposition:She ran up the hill.

In the first sentence, “up” doesn’t refer to anything. There is not object. Therefore, “up” is acting as an adverb here.

However, in the second example, “up” does refer to an object. For example, “up” is followed by a noun (the hill). As a result, it’s a preposition in this case.

You can confirm that “up” is a preposition here by asking and answering this question: Where did she run? She ran up the hill!

Here’s another one:

Adverb:Clark walked across.
Preposition:Clark walked across the courtyard.

In the first example, all we know is that Clark walked across something. We don’t know what that something is, because there is no object. Consequently, “across” is an adverb here.

In the second example, we find out that Clark walked across a courtyard. Since “courtyard” is the object, and across becomes a preposition.

Prepositional phrase cheat sheet. Prepositional phrases show the connections between parts of speech. A girl holding a rope with banners labeled as noun, pronoun, and supporting words. A prepositional phrase is a combination of a preposition and an object. Two types of prepositional phrases: adjectival phrases and adverbial phrases. A boy saying adjectival phrases are prepositional phrases that function as adjectives. A young woman saying adverbial phrases are prepositional phrases that function as adverbs. Some examples of prepositional phrases include by chance, in time, at the end, on schedule, in demand, out of breath, by accident, out of date, in danger, on a diet, in focus, at risk, by luck, and at sight. Preposition vs. adverb. A preposition needs and object. An adverb doesn't need an object.
