Prepositional Phrases

Prepositional phrases are groups of words that begin with a preposition and include its object, along with any words that modify the object. They add important details to sentences by showing relationships such as place, time, direction, and manner.

For example:

She sat on the chair.

In this sentence, “on the chair” is a prepositional phrase. On is the preposition, and the chair is its object.

Prepositional phrases can also work as adjectives or adverbs, helping describe nouns, verbs, and other parts of a sentence. Understanding how they work can help learners build clearer and more detailed sentences.

In this guide, you’ll learn how to identify and use prepositional phrases correctly with simple rules and examples.

What Is a Prepositional Phrase?

A prepositional phrase is a group of words that begins with a preposition and includes its object, which is usually a noun or pronoun, along with any words that modify the object.

Prepositional phrases add information to a sentence and commonly show relationships such as place, time, direction, or manner.

Examples:

• The cat is hiding under the table.
  Under the table tells us where the cat is hiding.
• She arrived after the meeting.
  After the meeting tells us when she arrived.
• They walked along the beach.
  Along the beach tells us where they walked.

In each example, the prepositional phrase begins with a preposition and ends with its object.

How to Identify a Prepositional Phrase

To identify a prepositional phrase, first find the preposition and then look for its object. The object is usually a noun or pronoun. Any words that modify the object are also part of the prepositional phrase.

Follow these simple steps:

1. Find the preposition.
Look for a word such as in, on, at, under, with, from, or after.

2. Find the object of the preposition.
Ask what or whom comes after the preposition.

3. Identify the complete phrase.
Include the preposition, its object, and any words that modify the object.

Example:

The children played in the large garden.

• in = preposition
• garden = object of the preposition
• the large garden = the object with its modifiers
• in the large garden = complete prepositional phrase

Another Example:

She went with her best friend.

• with = preposition
• friend = object of the preposition
• her best friend = the object with its modifiers
• with her best friend = complete prepositional phrase

Key Point: A prepositional phrase begins with a preposition and includes its object and any words that modify that object.

Prepositional Phrases as Adjectives

A prepositional phrase can function like an adjective by modifying a noun or pronoun. It provides more information about the word it modifies and often helps answer questions such as Which one? or What kind?

Examples:

  On the shelf modifies book and tells us which book.
• The girl in the red dress is my sister.
  In the red dress modifies girl and tells us which girl.
• The house by the lake is for sale.
  By the lake modifies house and tells us which house.
• The bag with the blue stripes is mine.
  With the blue stripes modifies bag and tells us which bag.
• The man from Spain teaches Spanish.
  From Spain modifies man and provides more information about him.

Prepositional Phrases That Modify Nouns

When a prepositional phrase modifies a noun, it functions like an adjective by providing more information about that noun. It often helps answer questions such as Which one? or What kind?

Examples:

• The girl in the red dress is my sister.

Prepositional Phrases, Adverbial Phrases, and Adjective Phrases

A prepositional phrase is identified by its structure, while adverbial and adjectival phrases are identified mainly by the job they do in a sentence. This means that a prepositional phrase can sometimes function like an adverb or an adjective.

A prepositional phrase can also perform an adverbial function:

• She sat on the chair.
  On the chair is a prepositional phrase that modifies sat by telling us where she sat.

A prepositional phrase can also perform an adjectival function:

• The book on the chair is mine.
  On the chair is a prepositional phrase that modifies book by telling us which book.

Key Point: Prepositional phrase describes the structure of the phrase, while adverbial and adjectival describe how a phrase can function in a sentence.

Prepositional Phrases That Modify Verbs

When a prepositional phrase modifies a verb, it functions like an adverb by providing more information about the action. It can tell us where, when, how, why, or how long an action takes place.

Examples:

• She walked through the park.
  Through the park modifies walked and tells us where she walked.
• They met after school.
  After school modifies met and tells us when they met.
• He laughed with joy.
  With joy modifies laughed and tells us how he laughed.

  For an hour modifies waited and tells us how long we waited.
• She danced under the stars.
  Under the stars modifies danced and tells us where she danced.

Prepositional Phrases with Pronouns

A pronoun can be the object of a preposition in a prepositional phrase. When a personal pronoun comes after a preposition, use its object form, such as me, you, him, her, it, us, or them.

Examples:

• The gift is for her.
  Her is the object of the preposition for.
• He walked beside me.
  Me is the object of the preposition beside.
• They waited for us.
  Us is the object of the preposition for.
• Please sit with them.
  Them is the object of the preposition with.

  Him is the object of the preposition from.

Remember: Use an object pronoun, not a subject pronoun, after a preposition.

• Correct: This gift is for her.
• Incorrect: Come with we.
• Correct: Come with us.
