What Are Prepositions?

Prepositions are words that show the relationship between a noun or pronoun and another part of the sentence. They help us understand:

• where something is
• when something happens
• the direction of movement
• the purpose or reason

For example, in the sentence The book is on the table, the word on shows the position of the book. Prepositions may be small, but they are essential for clear communication.

Using In, On, At (Time and Place)

The prepositions in, on, and at are often confusing because they are used for both time and place. Understanding their specific uses can help you avoid mistakes.

1. Using ‘In’

The preposition in is used for longer periods of time and for enclosed spaces.

Use ‘in’ for:

• months, years, and long periods
• places that are enclosed or surrounded

Examples:

• I was born in 2005.
• She will visit us in December.
• The keys are in my bag.
• He is in the room.

Here, in suggests something inside a space or within a period of time.

2. Using ‘On’

The preposition on is used for specific days and for surfaces.

Use ‘on’ for:

• days and dates
• surfaces

Examples:

• The meeting is on Monday.
• My birthday is on 5th July.
• The book is on the table.
• There is a picture on the wall.

Here, on suggests something placed on a surface or linked to a specific day.

3. Using ‘At’

The preposition at is used for exact times and specific points or locations.

Use ‘at’ for:

• exact time
• specific places

Examples:

• The class starts at 10 a.m.
• I will meet you at 6 o’clock.
• She is waiting at the door,
• He is at the bus stop.

Here, at refers to a precise point in time or place.

Using To, For, From

These prepositions are commonly used to show direction, purpose, and origin. They are often confused, so understanding their differences is important.

1. Using ‘To’ (Direction or Movement)

The preposition to is used to show movement from one place to another or direction towards something.

Examples:

• I am going to school.
• She walked to the market.
• He gave the book to me.
• We are travelling to Delhi tomorrow.

Here, to shows movement or transfer.

2. Using ‘For’ (Purpose or Benefit)

The preposition for is used to show purpose, reason, or benefit.

Examples:

• This gift is for you.
• I study for my exams.
• She bought flowers for her mother.
• This room is for meetings.

Here, for explains why something is done or who benefits from it.

3. Using ‘From’ (Starting Point or Origin)

The preposition from is used to show where something begins or where it comes from.

Examples:

• I came from Delhi.
• This letter is from my friend.
• The train leaves from platform 2.
• She borrowed the book from the library.

Here, from shows origin or starting point.
