Rules and Examples of In On Under Prepositions in Sentences

A group of words that we use ahead of noun, pronoun, or noun phrase to represent direction, time, place, location, spatial relationships, or even introduce an object are called prepositions. Some of the examples of prepositions are in, under, on, at, etc. Now, let us know the use of in on under with certain examples.


We can relate prepositions to our real-life experiences and then frame our own sentences. Prepositions can be of various types depending on the type of sentence you form.


Now, to understand what prepositions are, we will go through individual poems or stories on three prepositions - in, on, and under. Also, we will go through some more examples to understand prepositions in detail.


Poem of a Preposition ‘In’ - Little By Little

Here, we have to determine prepositions by highlighting the ‘in’ preposition.


Little by Little Poem - Class 3

Little by Little Poem


“Little by little,” an acorn said,

As it slowly sank in its mossy bed;

“I am improving every day,

Hidden deep in the earth away."


Little by little each day it grew,

Little by little, it sipped the dew.

Downward it sent out a thread-like root

Up in the air sprang a tiny shoot;


Day by day, and year by year,

Little by little the leaves appear,

And the slender branches spread far and wide

Till the mighty oak is the forest’s pride.


Story on a Preposition - On

One day, Jiya was sitting on the bench and wondering how beautiful is everything around me. It is really great to see birds sitting on the branches of the tree and a dog laying on the ground. I wish to remain here for my entire life.


Story on a Preposition - Under

Sheena can sit before the desktop (or in front of the desk). The teacher can  lay on the table (when she's being informal) or behind the table, and then her feet are under the chair or beneath the chair. She can stand behind the classroom door (meaning next to the desk), before the table, between the desk and you, or even on the desk (if she's a strange woman). 


If she's fat, he can bump into the desk or try to move through the table. Passing her hands over the table resting her hands upon the desk, she often looks across the  classroom and speaks as if there were nothing else like the classroom table. It’s because sometimes she wonders about her home, and how to reach there on time. Lastly, she leans against the desk and sleeps.

FAQs on Use of In On Under Prepositions in English Grammar

1. What is the difference between in, on, and under in English?

The difference between in, on, and under is that in shows something inside, on shows something touching a surface, and under shows something below another object.

  • In = inside a space (The keys are in the bag.)
  • On = touching a surface (The book is on the table.)
  • Under = below something (The cat is under the chair.)
These prepositions describe position and location in English grammar.

2. How do you use in as a preposition of place?

You use in to show that something is inside a closed or defined space.

  • Rooms, buildings, containers: She is in the room.
  • Cities and countries: They live in Canada.
  • Boxes or bags: The gift is in the box.
In answers the question “Where?” and indicates enclosure.

3. When should I use on in a sentence?

You should use on when something is touching or resting on a surface.

  • Tables, walls, floors: The phone is on the desk.
  • Pages or screens: There is a mistake on the page.
  • Streets: She lives on King Street.
On is commonly used for surfaces and specific locations.

4. How is under used in English grammar?

The preposition under is used to show that something is below or covered by something else.

  • Position: The shoes are under the bed.
  • Cover: He sat under a tree.
  • Age or amount (less than): Children under 12 enter free.
Under often indicates lower position or a smaller number.

5. What are the rules for using in, on, and under with time and place?

The basic rule is that in is used for larger areas or longer periods, on for surfaces and specific dates, and under for lower position or less than a number.

  • In time: in July, in 2025
  • On time: on Monday, on 5th June
  • Under numbers: under 18 years old
These prepositions follow common grammar patterns in English.

6. Can you give simple examples of in, on, and under in sentences?

Yes, simple examples help understand how in, on, and under work in context.

  • The milk is in the fridge.
  • The keys are on the table.
  • The dog is sleeping under the bed.
Each sentence clearly shows position and the correct use of the preposition.

7. Why do learners confuse in and on in English?

Learners confuse in and on because both describe location, but one means inside and the other means on a surface.

  • In = enclosed space (in a box)
  • On = surface contact (on a box)
The confusion often happens with transport and public places, so it is important to learn common usage patterns.

8. Is it in the bus or on the bus?

We usually say on the bus because public transport is treated as a surface or platform in English usage.

  • On the bus
  • On the train
  • On the plane
However, we say in a car or in a taxi because they are considered smaller enclosed spaces.

9. What is the difference between under and below?

The difference is that under often implies direct coverage or contact, while below simply means at a lower level.

  • The cat is under the table. (directly beneath it)
  • The temperature is below zero. (lower level, not physical contact)
Under is more common for physical position, while below is often used for measurements and levels.

10. How can I remember the correct use of in, on, and under?

You can remember the correct use by linking each preposition to a simple visual rule: inside, surface, and below.

  • In = inside a box
  • On = on top of a box
  • Under = under the box
Visualizing position helps learners master these common English prepositions of place.
