What Is a Preposition?

A preposition is a word that shows the relationship between a noun or pronoun and another word in a sentence.

For example:

• The book is on the table.
• Ali walked to school.
• We arrived at noon.
• She lives in Lahore.
• He works with his brother.

The preposition connects one part of the sentence to another and often shows place, time, direction, movement, manner, cause, or purpose.

The noun or pronoun that follows a preposition is called its object. In the sentence “The book is on the table,” the word table is the object of the preposition on.

Types of Prepositions

Prepositions can be grouped according to the relationship they express. The main types include:

Some prepositions can belong to more than one group depending on their use.

Prepositions of Time

Prepositions of time tell us when something happens. Common examples include at, on, in, since, for, by, and until.

At, On, and In

These three prepositions often cause confusion.

Use at for a specific time:

• The class starts at 9 a.m.
• I woke up at midnight.
• She arrived at noon.

Use on for days and dates:

• The exam is on Monday.
• He was born on 15 August.
• We met on Friday evening.

Use in for months, years, seasons, and longer periods:

• She was born in 2001.
• The course starts in September.
• We study more in winter.
• He will return in two weeks.

Since and For

Since shows the starting point of an action or situation.

• She has lived here since 2020.
• He has worked there since Monday.

For shows the length of time.

• She has lived here for six years.
• He has worked there for two months.

By and Until

By means no later than a particular time.

• Submit the form by Friday.
• I will finish the work by 6 p.m.

Until means an action continues up to a particular time.

• We waited until midnight.
• She stayed there until Monday.

Compare:

• Finish the report by Monday.
• Work on the report until Monday.

Prepositions of Place

Prepositions of place show where someone or something is located. Common examples include in, on, at, above, over, under, below, between, among, beside, and near.

In, On, and At

Use in for an enclosed space or larger area:

• The students are in the classroom.
• She lives in Pakistan.
• There is water in the bottle.

Use on for a surface:

• The phone is on the table.
• There is a picture on the wall.
• He sat on the chair.

Use at for a specific point or location:

• She is at the door.
• We met at the station.
• He is waiting at the bus stop.

Above and Over

Both above and over can indicate a higher position.

• The fan is above the table.
• A bridge passes over the river.

Over can also suggest movement or covering:

• The plane flew over the city.
• She put a blanket over the child.

Under and Below

Both can describe something at a lower position.

• The shoes are under the bed.
• The temperature fell below zero.

Under often suggests a direct position beneath something. Below can describe a lower level, position, or measurement.

Between and Among

Use between when talking about separate people or things, especially two.

• The agreement was between the two countries.
• Divide the money between Ali and Ahmed.

Use among when talking about a group.

• She was sitting among her friends.
• The teacher distributed the books among the students.

Prepositions of Direction and Movement

These prepositions show movement from one place to another. Common examples include to, from, into, onto, through, across, along, past, and towards.

To and From

To shows movement toward a place.

• She went to school.
• They travelled to Islamabad.

From shows the starting point.

• He came from Lahore.
• The train arrived from Karachi.

In and Into

In usually describes position.

• The children are in the room.

• He got into the car.

On and Onto

On usually describes position on a surface.

• The book is on the desk.

Onto usually shows movement toward a surface.

• The cat jumped onto the desk.

Through and Across

Through means movement from one side or part of something to another, often within an enclosed area.

• We walked through the tunnel.
• The train passed through the city.

Across means movement from one side to another.

• They walked across the road.
• She swam across the river.

Along, Past, and Towards

Along shows movement following a line, path, or edge.

• We walked along the river.

Past shows movement beyond a person, place, or point.

Towards shows movement in the direction of something.

Prepositional Phrases

A prepositional phrase begins with a preposition and normally contains a noun or pronoun as its object.

Examples include:

• in the room
• on the table
• after the meeting
• with my friends
• under the bridge

Prepositional phrases can provide extra information about place, time, direction, manner, or other relationships.

For example:

The students waited in the classroom.

The phrase in the classroom tells us where the students waited.

Another example:

We met after the exam.

The phrase after the exam tells us when we met.

Common Preposition Combinations

English uses many fixed combinations with particular verbs and adjectives. These combinations are worth learning because changing the preposition can make the sentence incorrect.

Common Verb + Preposition Combinations

Common Adjective + Preposition Combinations

Learning these combinations as complete phrases is often easier than memorizing isolated prepositions.

Common Preposition Mistakes

Prepositions create problems because English usage does not always match direct translation from another language. Here are some common mistakes.

Mistake 1 – Using In, On, and At Incorrectly

Mistake 2 – Using the Wrong Fixed Combination

Mistake 3 – Adding an Unnecessary Preposition

Some verbs already contain the required meaning and do not need an extra preposition.

However, enter into can be correct in specific expressions such as enter into an agreement.

Mistake 4 – Translating Prepositions Directly

A preposition that works in one language may not work the same way in English.

• married to someone
• different from something
• good at something
• interested in something

These combinations should be learned through examples and regular use.

Commonly Confused Prepositions

Some pairs look similar but have different meanings. Master these and you will avoid the most common preposition traps in exams.

Beside and Besides

Beside means next to.

• She sat beside me.

Besides means in addition to.

• Besides English, he studies Urdu.

By and With

By often identifies the person who performs an action.

• The novel was written by the author.

With can show the instrument or tool used.

• He cut the paper with a knife.

To and For

To often shows direction or the receiver of something.

• I gave the book to Ahmed.

For often shows purpose, benefit, or intended use.

• I bought the book for Ahmed.
• This room is for students.

In and Into

In describes position.

• She is in the office.

Into shows movement toward the inside.

• She walked into the office.

On and Onto

On describes position.

• The keys are on the desk.

Onto shows movement toward a surface.

• He put the keys onto the desk.

How to Learn Prepositions More Easily

Memorizing a long list of prepositions is not enough. You also need to understand how each one works in a sentence.

Start with common groups such as:

• at, on, in for time and place
• since, for for time
• to, from for direction
• in, into for position and movement
• between, among for relationships
• by, with for different types of relationships

Then learn common verb and adjective combinations as complete phrases.

Reading English regularly can also help you notice how native speakers use prepositions in real sentences. Writing your own examples is another useful method. If you repeatedly make the same mistake, record the correct sentence and review it later.

Prepositions for Competitive Exams

Prepositions are frequently tested in English grammar sections of competitive examinations. Candidates preparing for CSS, PMS, FPSC, PPSC, and similar exams should focus on usage rather than memorizing random lists.

Questions may test:

• Correct preposition selection
• Fill-in-the-blank sentences
• Error detection
• Sentence correction
• Confusing preposition pairs
• Fixed verb-preposition combinations
• Fixed adjective-preposition combinations
• Meaning and usage in context

How to Revise Prepositions

Revision is where knowledge becomes marks. Follow this sequence for maximum retention.

• Start by learning the most common prepositions and their basic uses.
• Next, study confusing pairs such as in and into or since and for.
• After that, practice sentence correction and fill-in-the-blank questions.
• Competitive-exam candidates should review fixed combinations because these often appear in grammar questions.
• Finally, write your own sentences. Correcting your repeated mistakes will help you remember the right usage.
