What is Letter Writing? And Why Does It Still Matter?
A letter is a written message addressed to a person, a group, or an organisation. Even in the age of emails and WhatsApp, letters remain one of the most important forms of written communication โ in exams, in offices, in legal matters, and in everyday life.
When you write a letter, you are not just conveying information โ you are representing yourself. A well-written letter shows that you can organise your thoughts, choose the right tone, and communicate with clarity and respect. That is a life skill no exam can take away from you.
The Three Pillars of a Good Letter
Purpose
Every letter has a clear reason for being written โ requesting, complaining, informing, thanking, or congratulating. Define yours before you write a single word.
Tone
Formal letters use polite, professional language. Informal letters can be warm and personal. Matching your tone to your audience is the #1 skill in letter writing.
Format
Letters follow a fixed structure. Marks are awarded for format in exams. Getting the layout right is as important as the content you write.

Sub-Types of Formal Letters
Complaint Letter
Written to report a problem and ask for resolution
A complaint letter is used when you want to report a problem โ a faulty product, poor civic facilities, a broken streetlight, disruption in water supply, and so on. The key is to be factual, polite, and specific. Never use rude or aggressive language, even if you are genuinely upset.
What to Include:
- Who you are (resident, customer, student)
- What exactly the problem is (with date/location if possible)

Request / Application Letter
Written to ask for leave, permission, certificate, NOC, etc.
Request letters are among the most practical types of formal letters. You may need to write one to your Principal asking for leave, to your employer requesting a salary certificate, or to a government office for a duplicate document.
Key Phrases for Request Letters:
- "I am writing to respectfully requestโฆ"
- "I would be grateful if you could kindlyโฆ"
- "I request you to please grant meโฆ"
- "I assure you thatโฆ"
- "I hope my request will be given due consideration."
Letter to the Editor
Written to a newspaper or magazine on a social/civic issue
This is one of the most frequently asked letter types in CBSE Class 10 and 12 exams. It is a formal letter addressed to the Editor of a newspaper, written by a concerned citizen on a social issue โ pollution, traffic, inadequate civic amenities, child labour, water scarcity, or rising prices.
Structure of a Letter to the Editor:
- Para 1: Introduce the issue you're writing about. Mention why it's important and urgent.

- Para 3: Suggest solutions and request the editor to publish your letter to raise awareness.
Useful Phrases:
- "Through the columns of your esteemed newspaper, I wish to draw attention toโฆ"
- "This is a matter of grave concern for the residents ofโฆ"
- "I hope the concerned authorities will take cognisance of this issue."
- "I request you to kindly publish this letter in your newspaper."
Informal Letters โ Writing with Heart
Informal letters are written to people you know and care about โ friends, cousins, grandparents, or a pen pal. The language is warm, personal, and conversational. No stiff "I humbly submit" here โ just genuine human connection on paper.
Informal Letter Format
Sound Natural
Use contractions ("I'm", "you've", "it's"), everyday vocabulary, and rhetorical questions like "Can you believe it?"
Ask Questions
Informal letters feel like a real conversation. Ask your friend how they're doing, what they've been up to, and reply to their last letter.
Warm Openings
Start with "I was so happy to receive your letter!" or "It's been ages since we spoke!" โ engage the reader from line one.
Warm Closings
End with "Give my love to your family," "I can't wait to hear from you soon!" โ closings matter in informal letters.
Common Types of Informal Letters
Invitation Letter
Inviting a friend or relative to an event or occasion
Invitation letters are among the most delightful to write! Whether it is a birthday party, a family function, a cultural programme, or a wedding, the goal is to make your reader feel genuinely excited and welcome.
Must-Include Details:
- The event (what it is)
- Date and time
- Venue / location
- Why you want them to be there
- Any special instructions (dress code, RSVP, bring something)
Describing a Holiday / Place
Sharing your travel experience with a friend or relative
These letters appear very often in exams. You're asked to describe a trip you went on โ to a hill station, a historical monument, a beach, or a city โ in a letter to your friend. The secret is sensory detail.
Descriptive Language to Use:
- Sights: "the snow-capped peaks of Manali were breathtaking"
- Sounds: "the gentle sound of waves crashing at Marina Beach"
- Food: "we devoured the most delicious Rajasthani thali in Jaipur"
- Feelings: "I felt a sense of peace I hadn't felt in months"
- People: "the locals were so warm and hospitable"
Advice Letter
Giving guidance to a friend facing a problem or decision
Advice letters are a fantastic exercise in empathy and reasoning. Your friend might be struggling with a career choice, a relationship issue, or a personal problem. You need to acknowledge their situation before jumping in with advice โ this is both good manners and good writing.
Structure:
- Acknowledge: "I was sorry to hear about your difficultyโฆ"
- Empathise: "I can imagine how stressful this must be for you."
- Advise: Give 2โ3 clear, practical suggestions.
- Encourage: End on a positive, supportive note. "I know you can get through this!"

Tips & Tricks โ Score Full Marks
These are the actionable, exam-tested strategies that top scorers use. Read them, remember them, apply them.
Always Write the Subject Line
The subject line is worth 1 dedicated mark in most boards. Keep it specific โ "Complaint Regarding Water Shortage" beats "Regarding a Problem."
Plan Before You Write
Spend 2 minutes listing the 3โ4 points you want to cover. A well-organised letter always scores more than a rushed, rambling one.
Stick to 3 Body Paragraphs
Introduction โ Details โ Request/Conclusion. Three focused paragraphs are always better than five scattered ones in a letter.
Write the Date Correctly
Always write dates in full: "14 July 2025" โ not "14/07/25" or "July 14th, 2025." This tiny detail separates average from excellent answers.
Vary Your Sentence Length
Mix short punchy sentences with longer ones. "This is unacceptable. Three children have been injured near this spot in the last month alone." Power + detail = impact.
Stay Calm in Complaint Letters
Never write "I am furious" or "This is disgusting." Replace with "I am deeply concerned" and "This situation is completely unacceptable." Same feeling, professional tone.
Use Formal, Not Informal Words
"Purchase" not "buy." "Residence" not "house." "Commence" not "start." "Request" not "ask." These swaps instantly elevate your register.
End With a Clear Action Request
Every letter should end by telling the reader exactly what you want them to do: repair the road, grant the leave, publish the letter, invite for an interview.
Re-read the Question Twice
The question tells you: who you are, who you're writing to, and what the issue is. Missing one detail means losing format marks. Read it twice before writing.
