English:Prepositions and Prepositional Phrases
Prepositions and Prepositional Phrases
Introduction
Prepositions are small words with an important job. They show how people, places, things, and ideas are connected. A preposition can tell you where something is, when something happens, where something moves, or another kind of relationship.
Look at this sentence: The puppy sleeps under the table. The word under shows the relationship between the puppy's position and the table.
A prepositional phrase begins with a preposition and includes the word or group of words that completes its meaning. In under the table, under is the preposition and table is the object of the preposition. The complete prepositional phrase is under the table.
The picture above shows several location relationships. Try to describe each picture aloud before reading further.
In this course, you will learn to recognize common prepositions, build prepositional phrases, explain what those phrases do in sentences, and use them to make your own speaking and writing clearer.
What Is a Preposition?
A preposition is a relationship word. In English, a preposition usually comes before a noun, pronoun, or noun phrase that completes its meaning.
Examples: The ball is under the chair. We arrived after lunch. Mina walked toward the library. The class made a poster with markers.
In these examples, under, after, toward, and with are prepositions. Their objects are chair, lunch, library, and markers.
Common prepositions include in, on, at, under, over, above, below, beside, between, near, behind, before, after, during, from, to, toward, through, across, with, without, for, by, and of.
You do not need to memorize one giant list. It is more useful to ask, “What relationship does this word show here?”
Prepositions of Place
Prepositions of place tell where something or someone is.
In often means inside an area or container: The pencils are in the box.
On often means touching a surface: The notebook is on the desk.
Under means lower than something: The backpack is under the chair.
Between means in the space separating two things or groups: The library is between the school and the park.
Behind means at the back of something: The bicycle is behind the shed.
In front of means on the forward side of something: We waited in front of the theater.
Next to means directly beside something: My seat is next to the window.
Notice that the best preposition depends on the meaning you want. A bird can be above a tree without touching it, while a book is on a table when it rests on the surface.
Prepositions of Time
Prepositions of time tell when something happens.
Use at for a specific clock time or point in time: at 7:30, at noon.
Use on for days and dates: on Monday, on August 12.
Use in for longer periods such as months, years, seasons, or parts of the day: in May, in 2026, in winter, in the morning.
Other useful time prepositions include before, after, during, until, since, and for.
Examples: Before class, I sharpen my pencil. We read quietly during study time. The team practiced after school. The museum is open until five o'clock.
Prepositions of Direction and Movement
Prepositions can also show movement.
To can show an endpoint: We walked to the gym.
Toward shows movement in a direction: The dog ran toward the gate.
Into shows movement from outside to inside: She dropped the letter into the box.
Out of shows movement from inside to outside: The rabbit hopped out of the basket.
Across shows movement from one side to another: We walked across the field.
Through shows movement within and from one side of a space to another: The train went through the tunnel.
A useful question is: Is the sentence describing a position, or is it describing movement? Compare The cat is in the box with The cat jumped into the box.
Building Prepositional Phrases
A basic prepositional phrase has two main parts:
preposition + object
Examples: under + the desk becomes under the desk after + lunch becomes after lunch with + her friend becomes with her friend
The object is usually a noun or pronoun. Words that describe the object can be part of the phrase too.
In under the old wooden desk: under is the preposition, desk is the object, and the old wooden adds information about the desk.
So the whole prepositional phrase is under the old wooden desk.
Finding the Object of a Preposition
To find the object, first find the preposition. Then ask, “Preposition plus what?” or “Preposition plus whom?”
beside the river → beside what? river
with them → with whom? them
after the long rehearsal → after what? rehearsal
Be careful not to choose a describing word as the object. In under the bright blue blanket, the object is blanket, not bright or blue.
What Does a Prepositional Phrase Do?
A prepositional phrase adds useful detail. It often works like an adverb or an adjective.
When it tells more about a verb, it can answer questions such as where, when, how, or in what direction.
Lena read in the library. The phrase in the library tells where Lena read.
We left after lunch. The phrase after lunch tells when we left.
When a prepositional phrase tells more about a noun, it helps identify or describe that noun.
The book on the shelf is mine. The phrase on the shelf tells which book.
The student with the red backpack waved. The phrase with the red backpack tells which student.
You can test the phrase by asking, “What word does this phrase give more information about?”
Place, Time, and Meaning
A single preposition can have more than one meaning. Context tells you which meaning is intended.
at the door shows place. at three o'clock shows time.
on the table shows place. on Friday shows time.
in the classroom shows place. in July shows time.
This is why learning prepositions through complete sentences is more useful than learning them as isolated words.
Using Prepositional Phrases in Sentences
You can move some prepositional phrases to different places in a sentence.
After dinner, we played a board game. We played a board game after dinner.
Both sentences are clear. The first version puts the time information first.
A prepositional phrase at the beginning of a sentence may be followed by a comma, especially when the phrase is long or when more than one introductory phrase appears. Short introductory phrases often do not need a comma.
In the morning we packed our bags. After a long and exciting day at the science museum, we rode home.
Do not put a comma between the main subject and its verb just because a prepositional phrase comes between them.
The box of old photographs is heavy.
The main subject is box. The phrase of old photographs adds information about the box.
Subject-Verb Agreement and Prepositional Phrases
A noun inside a prepositional phrase is usually not the main subject of the sentence.
The basket of apples is on the counter.
The subject is basket, so the singular verb is matches it.
The baskets of apples are on the counter.
The subject is baskets, so the plural verb are matches it.
A helpful strategy is to temporarily cover the prepositional phrase:
The basket ... is on the counter.
This makes the subject and verb easier to match.
Common Tricky Choices
In, On, and At for Place
Use in when something is inside an area or space: in the room, in the city.
Use on when something is on a surface: on the wall, on the floor.
Use at when you mean a point or general location: at the bus stop, at school.
English has many fixed expressions, so meaning and common usage matter. Reading and listening to many correct examples will help these patterns feel familiar.
In, On, and At for Time
A simple guide is: at for a point in time, on for a day or date, in for a longer period.
Examples: at 4:00 on Tuesday in October
There are some fixed expressions that do not follow a simple chart perfectly, such as at night. When you meet one, learn it as a useful phrase.
Between and Among
Between is commonly used when separate people or things are treated individually: The path runs between the two buildings.
Among is commonly used when something is part of a group: She found her notebook among the papers.
For Grades 5–6, focus on the meaning of the relationship rather than trying to force every sentence into a single shortcut.
To and Into
To usually shows a destination: We went to the pool.
Into usually shows movement from outside to inside: We jumped into the pool.
Compare the meaning carefully before choosing.
Editing for Clearer Writing
Prepositional phrases can make writing more exact, but too many in a row can make a sentence hard to follow.
Less clear: The box on the shelf by the window in the room near the stairs belongs to me.
Clearer: The box on the shelf belongs to me. The shelf is by the window near the stairs.
When you revise your writing, ask: Is each prepositional phrase useful? Does the reader know what the phrase describes? Would moving or removing a phrase make the sentence clearer?
Good writers use prepositional phrases to add information, not to bury the main idea.
