Why is Letter Writing as a tool essential?

  • Thoughtful and Personal Communication: Letter writing allows individuals to express themselves in a thoughtful and personal manner. It allows for meticulous composition of thoughts, emotions, and ideas, allowing for deeper reflection and meaningful expression. Letters, as opposed to instant messaging or short digital contact, provide for a more methodical and thoughtful form of communication.
  • Letters create a concrete and long-lasting record of conversation. They can be saved and accessed in the future as a recorded record of shared events, emotions, and connections. Letters can be treasured as treasures and passed down through generations, providing a window into the past.
  • Formal and Professional Communication: Formal letter writing is still important for professional and corporate communication in some situations. Formal letters uphold a professional tone, give a written record of agreements or discussions, and function as official documentation. They are frequently used in job applications, cover letters, business proposals, and formal correspondence.
  • Emotional Connection: Letters have the ability to create emotional relationships. Letters may transmit feelings in a powerful and personal way, whether it’s a love letter expressing deep passion, a heartfelt apology, or a sympathy letter bringing consolation during tough times. Receiving a real letter can create feelings of care, thoughtfulness, and importance that digital communication may lack.
  • Time, effort, and concentration are all required when writing a letter. It reflects the sender’s dedication to meaningful communication. The sender demonstrates respect and regard for the recipient by taking the time to create a letter, building better connections and relationships.
  • Letter writing has been an important aspect of human history and culture for thousands of years. Letters have been used to document many key historical events and personal tales. Preserving the custom of letter writing helps to preserve cultural history and provides insight into the thoughts, values, and experiences of people from various times.



There are certain essential tips that one should follow and remember when writing a letter. 

  1. Understand the Purpose: Before you begin writing, clearly understand the purpose of your letter. Having a clear aim will help you arrange your letter effectively, whether you’re making a request, offering information, or expressing a worry.
  • Be Polite and Respectful: Throughout the letter, use courteous and respectful language. Avoid strong or confrontational tones, as well as unpleasant or insulting remarks. Maintain a courteous demeanor towards the receiver.
  • Organize the Information: Divide your letter into paragraphs to make it more reasonable. Each paragraph should concentrate on a single point or issue. Begin with an introduction, then move on to supporting paragraphs before concluding with a clear conclusion or request.
  • Include pertinent information: To reinforce your point, include pertinent information, facts, or supporting proof. To help the recipient comprehend your point of view or comply with your request, be specific and supply factual facts.
  • Proofread and edit your message completely before sending it to ensure that it is free of grammar, spelling, and punctuation issues. Examine for clarity and coherence. Edit your letter to verify that it is well-organized and effectively expresses your message.

Here are a few solved examples of letters

Example 1: Your friend, Utkarsh has been living abroad for several years. Write a letter to him describing some of the recent changes in your city. You are Alok living at B-3, Mansarovar Park, Nehru Nagar, Delhi.   


B-3, Mansarovar Park,

Nehru Nagar,


5 January 2021

Dear Utkarsh

I was pleased to learn that you will be seeing your sister in India on August 12th. It would be fantastic to meet you. As the Metro rail begins and runs through the major roads, you will be unable to recognise the place. Many new retail malls have also proven popular with young people. You used to taunt the shopkeeper, but now he’s a big businessman who drives around in flashy new cars. You would also be unable to recognise our school, which has been renovated and given a new appearance. I’m waiting for you.

Sincerely Yours


Example 2: Write a letter to the Editor about a road that needs repair. 

Ans. 1, Rana Pratap Marg

New Delhi

01 March, 20XX

The Editor

The Hindu 

New Delhi 

Subject: Repair of the road in Cheran Nagar


I would like to bring to your notice that the people in and around Rana Pratap Marg have been facing difficulties in traveling back and forth because of the bad condition of the roads there. We have appealed to the Municipality, but there has not been any response on the issue so far.

Because our petitions to their office have been ignored, we believe that a mention in the media would be extremely beneficial. Our neighborhood’s roads have been nearly impassable since the beginning of the month. The surface has been severely damaged by the heavy rains, and passing automobiles on a dark night is quite perilous. Furthermore, there are piles of road metal on both sides of the road, leaving very little space in the center. Residents in the region have been inconvenienced in this manner for several weeks.The situation is becoming worse. There have been multiple accidents happening due to this condition. 

I request you to highlight the seriousness of the matter in your newspaper so that the road may be properly repaired without further delay.

Thanking You

Yours sincerely

Vikrant & Co., Manali
Himachal Pradesh- 360087

Subject- Complaint and feedback letter

Dear Sir

I wish to inform you about my stay at your hotel from 02/03/2021 to 06/03/2021. I regret to inform you that my family and I are quite unsatisfied with the stay at your hotel.

We came to know about your hotel from a travel site. Although the pictures and reviews were quite decent, the actual experience didn’t conform to the standards. For instance, the bed sheets and quilts were dirty; the staff was not cooperative and the room service was slow. We were made to pay separately for the cab service even though the website mentioned that the accommodation charges included a free cab.

I suggest you look into these matters carefully as they will help to improve your service and ensure a better experience for the customers. Moreover, it would be better if you could mention the correct information about the facilities, which you are willing to provide on the partner websites.

Thanking you
Yours truly

I hope we can reschedule the get-together and not miss the chance to meet up. Waiting to hear from you.

Example 8: People have adapted to wearing face masks as a ‘new normal’. But most of them do not know how to dispose of them properly. Spread awareness regarding the disposal of protective masks by writing a letter to an editor of a popular newspaper.

22, Airport Road
New Delhi

12th June 2022

The Editor
The Times
New Delhi

Subject: An appeal to raise concern about the incorrect disposal of protective masks


With great respect and faith in the columns of your newspaper, I, ABC, a resident of Airport Road, am writing to you. I want to inform you that face masks, which are widely used for safety against Covid-19, are being discarded in inappropriate locations by a segment of the population.

Face masks are being worn by a growing number of individuals to be safe from the disease, but disposing them away anywhere is not acceptable as it can cause many health related as well as environmental issues. People dump these masks carelessly in places like roadsides, pavements, gardens, etc. The elastic bands on these can pose a death threat for the animals who mindlessly chew them. Also, these are a hub of germs and microbes and can spread infections. Proper disposal of face masks is crucial for prevention of spread of diseases. 

I would like to request the residents, through the columns of your prestigious publication, to stop careless discarding of their used masks. The government agencies should sensitize people regarding this issue.

Thanking you in anticipation

Yours sincerely

Example 9: Write a letter to Your Cousin Enquiring about Her First Visit to Ethiopia


34, Park Avenue
Mumbai – 400023

24th September, 2021

Dearest Maria

I was so glad to hear from my mother that you are back home after the trip. Hope you had a safe and enjoyable trip. I have been waiting to hear all about the trip from you.

Since this was the first time you have been to a foreign land, I guess every little bit of the trip was as exciting as you expected it to be. I have heard from my friends residing there that the place is extremely beautiful and that the people there are very endearing. However, I was worried when I saw the news about the few bomb blasts during your stay there. Hope all of you there were safe. I hope everything else was fine except for this.

I had spoken to your mother earlier, and she told me that you would be coming home after two weeks. I saw your pictures on Instagram as well. I can’t wait to meet you and hear all your stories. Waiting eagerly for your reply.

Your loving cousin


Example 10: You are Naresh / Nandini of Safdarjung, New Delhi. You are deeply saddened by the attacks on elderly persons who live alone. Write a letter to the editor of ‘The New India News’ making people aware of the authorities to guarantee that such attacks do not occur.

Ans. Safdarjung

New Delhi
12th June 2022

The Editor
The New India News
New Delhi

Subject: Issue of lack of security and attacks on old people


I am a resident of Safdarjung and through the columns of your esteemed newspaper, I’d like to bring attention to the issue of elderly abuse. Physically, the elderly are often frail. As a result, they can’t face the rogues who usually come to rob them.

Any opposition from the elderly can be dangerous to their wellbeing. Many incidents of robbery, pickpocketing, and severe attacks on the elderly have occurred in the Safdarjung Area. Recently, an old aged couple was hacked to death in broad daylight. This has created fear among the seniors.

It is the government’s responsibility to safeguard the lives of senior residents. I suggest that the resident welfare associations should form small groups which visit the lonely couples a few times a day and keep a check on their wellbeing.

Unfortunately, there has been no action despite many inquiries and requests to the authorities.

Perhaps the words in your prestigious publication will do the needful.

Thank you
Yours truly
Naresh / Nandini
