A preposition is a word placed before a noun or pronoun to show its relation with another word in the sentence. This relation may indicate place, time, direction, movement, cause, manner, possession, or condition.
In simple terms, a preposition answers questions like where, when, how, to whom, from where, by what means.
Examples:
- The book is on the table.
- She arrived at noon.
- He is good at mathematics.
In examinations, prepositions are tested less by definition and more by correct sense and fixed usage. A single wrong preposition can make an otherwise correct sentence incorrect.

Preposition as a Relational Word
A preposition always connects:
- a governing word (verb, adjective, or noun)
- with a noun or pronoun (called the object of the preposition)
Example:
- He depends on his parents.
Here:
- depends is the governing verb
- on is the preposition
- parents is the object of the preposition
Object of a Preposition
The noun or pronoun that follows a preposition is called its object.
A preposition must always have an object.
Example:
- She sat on the chair.
This rule helps eliminate incorrect options where a preposition is left hanging without an object.
Classification of Prepositions (Exam-Relevant)
For clarity and application, prepositions are studied under:
- Prepositions of Place
- Prepositions of Time
- Prepositions of Direction and Movement
- Prepositions used with Verbs
- Prepositions used with Adjectives
- Prepositions used with Nouns
- Fixed Prepositional Phrases
Prepositions of Place
Prepositions of place show position or location.
At, In, On (Most Tested Set)
- At is used for a point or specific place.
- In is used for an enclosed space or large area.
- On is used for a surface.
Examples:
- He is at the gate.
- She lives in Delhi.
- The book is on the table.
Exam-Trap Clarification: At / In / On
Common mistake
Using these interchangeably.
Correct explanation
at → exact point
in → enclosed or large area
on → surface
Examples:
He is in the bus. (inside)
He is on the bus. (public transport usage)
Exam rule:
Visualise position before choosing the preposition.
Prepositions of Time
Prepositions of time show when something happens.
At, In, On (Time Use)
- At → exact time
- On → specific day or date
- In → longer periods (month, year, century)
Examples:
- The train arrives at 6 a.m.
- The exam is on Monday.
- He was born in 2002.
Exam-Trap Clarification: Time Prepositions
Common mistake
Using in for clock time or at for months.
Exam rule:
At = clock time, On = day/date, In = long duration.
Prepositions of Direction and Movement
These prepositions show movement from one place to another.
Common ones:
to, into, onto, from, towards, across
Examples:
- He went to the market.
- She jumped into the river.
- The boy ran across the road.
Exam-Trap Clarification: To vs Into
Common mistake
Using to where into is required.
Explanation:
to → movement towards
into → movement inside
Example:
He walked into the room. (entered)
Prepositions Used with Verbs
(Extremely High-Frequency Exam Area)
Some verbs require specific prepositions. Changing the preposition changes meaning or makes the sentence incorrect.
Examples:
- depend on
- believe in
- consist of
- belong to
- listen to
Example sentences:
- She depends on her sister.
- This book belongs to me.
Exam-Trap Clarification: Verb + Preposition
Common mistake
Using a literal preposition instead of fixed usage.
Wrong:
He discussed about the issue.
Correct:
He discussed the issue.
Exam rule:
Some verbs take no preposition at all.
Prepositions Used with Adjectives
Many adjectives are followed by fixed prepositions.
Examples:
- good at
- afraid of
- interested in
- proud of
- confident of
Example sentences:
- He is good at maths.
- She is afraid of dogs.
Exam-Trap Clarification: Adjective + Preposition
Common mistake
Using in everywhere.
Wrong:
She is good in English.
Correct:
She is good at English.
Exam rule:
Adjectives demand fixed prepositions, not logical ones.
Prepositions Used with Nouns
Some nouns are also followed by fixed prepositions.
Examples:
- reason for
- solution to
- interest in
- demand for
Example sentences:
- There is no solution to this problem.
Preposition vs Adverb (Boundary Condition)
Some words look like prepositions but act as adverbs when no object follows.
Examples:
- He went inside. (adverb)
- He went inside the room. (preposition)
Exam-Trap Clarification: Preposition vs Adverb
Exam rule:
If a word has an object, it is a preposition.
If not, it is an adverb.
Ending a Sentence with a Preposition
In modern exam grammar, ending a sentence with a preposition is acceptable, especially in questions
Example:
- This is the house I live in.
Avoid over-correction in exams.
Common Fixed Prepositional Phrases (Exam-Safe)
- in spite of
- according to
- because of
- due to
