ICSE Class 9 Letter Writing: Formal and Informal Letters with Examples

Updated 15 October 2026 · Fact-checked

Question 2 of ICSE English Paper 1 gives a choice of two letters, one formal and one informal, and you write one. In Class IX your school sets the paper on the same syllabus. Marks go to format, content and expression: complete addresses and date, the correct salutation and subscription, every point developed, and the right tone.

What Letter Writing is about

Letter writing is Question 2 of English Paper 1. The CISCE syllabus for Classes IX and X asks for 'a letter from a choice of two subjects requiring either a formal or a friendly mode of treatment' and warns that 'the format of the letter with address, introduction, conclusion, etc., will form part of the assessment'. Tone and vocabulary must suit the reader.

In the board layout (CISCE's 2027 specimen) the letter carries 10 marks and the advised time is not more than 20 minutes. Your Class IX paper is set and marked by your school, but schools follow the same syllabus and usually the same layout, so the habits you build now carry straight into Class X.

CISCE has published its own suggested formats (Specimen Questions 2026): a friendly letter to parents and a formal complaint to a Municipal Commissioner, each shown in block and indented layouts with the note 'Any one format may be followed, all are acceptable.' Two features surprise many pupils: there is no subject line in CISCE's formal letter, and the formal salutation is simply 'Dear Sir,'.

The draft marking scheme sums up the assessment in three words: format, content, expression. Content means covering *every* point the question names (for example, a complaint *and* suggestions) and developing each with detail.

Weightage: Question 2: one letter out of two (formal or informal). In the board pattern it carries 10 of the 80 marks of Paper 1, about 20 minutes. Class IX papers are set by schools on the same syllabus.Source: CISCE ICSE 2028 English syllabus (Paper 1, Question 2); CISCE ICSE 2027 Specimen Question Paper, English Paper 1

Key concepts

Informal (friendly) letter layout

Write to family members and friends. In CISCE's sample the parts are, in order:
1. Your address (house, street, locality, city with PIN), each line ending with a comma and the last with a full stop.
2. Date in full, e.g. '16th September 2025'.
3. Salutation: 'My dear Mother and Father,' / 'Dear Kabir,'.
4. Body in paragraphs: a warm opening, the points the question asks for, a closing paragraph.
5. Subscription: 'With love,' / 'Yours affectionately,' (no apostrophe in 'Yours').
6. First name only.
There is no receiver's address and no subject line.

Worked example

Put these jumbled parts of a friendly letter in order: 'Yours lovingly,'; '14, Lake View Road, Dhakuria, Kolkata – 700 031.'; 'Dear Didi,'; 'Tanvi'; '3rd March 2027.'; body paragraphs.

Try it first, then show the solutionSolution
  1. Sender's address first, then the date.
  2. Salutation, then the body.
  3. Subscription, then the first name.

Answer: 14, Lake View Road, / Dhakuria, / Kolkata – 700 031. / 3rd March 2027. / Dear Didi, / body / Yours lovingly, / Tanvi

Formal letter layout

Write to officials, editors, principals, companies. CISCE's sample has:
1. Sender's address and date (as above).
2. Receiver's designation and address: 'The Municipal Commissioner, / Kolkata Municipal Corporation, / ... / Kolkata – 700 126.'
3. Salutation: 'Dear Sir,' or 'Dear Madam,' (or 'Dear Sir/Madam,' when you do not know).
4. Body: purpose in the first paragraph, details and suggestions in the middle, a polite closing ('I look forward to your cooperation in this matter.').
5. 'Thanking you,' (optional) and 'Yours faithfully,'.
6. Full name.
No subject line appears in CISCE's formats, and your name never goes above your address.

Worked example

Write the receiver's block for a letter to the Principal of your school, Green Valley School, Sector 21, Noida.

Try it first, then show the solutionSolution
  1. Designation first, not a personal name.
  2. Then the institution and its address, ending with the PIN.

Answer: The Principal,
Green Valley School,
Sector 21,
Noida – 201 301.

Salutation and subscription must match

The pair you choose shows whether you understand the letter's mode.

  • Formal: 'Dear Sir,' / 'Dear Madam,' → 'Yours faithfully,' + full name.
  • Informal: 'Dear Grandpa,' / 'My dear Riya,' → 'Yours affectionately,' / 'Yours lovingly,' / 'With love,' + first name.

CISCE examiners have repeatedly listed 'Respected Sir' and 'Yours sincerely' in formal letters, 'Your humble servant', and 'Your's' (with an apostrophe) among format errors.

Worked example

Correct this ending of a complaint to a bank manager: 'Your's obediently, Rahul'.

Try it first, then show the solutionSolution
  1. Formal letter, so 'Yours faithfully,'.
  2. No apostrophe in 'Yours'.
  3. Full name, not first name only.

Answer: Yours faithfully,
Rahul Menon

Content: cover every point and develop it

Each question names its points: 'how you felt', 'why you think', 'what your plans are'; or 'complain' and 'offer suggestions'. Underline each one and give it at least two specific details. A complaint letter, for instance, needs the problem described concretely (since when, where, its effects) and practical suggestions that the reader can actually carry out. CISCE examiners (2025) criticised answers that only asked the official to 'look into the matter or take necessary action', and those that offered just one obvious solution.

Worked example

Develop the point 'the street lights do not work' into two specific sentences for a formal complaint.

Try it first, then show the solutionSolution
  1. Say where and since when.
  2. Say what harm it causes.

Answer: 'Six of the eight street lights on Gandhi Marg, between the post office and the bus depot, have not worked since 2nd July. Since then two two-wheelers have skidded on the potholes after dark, and parents no longer allow their children to walk back from tuition alone.'

Tone and vocabulary

A friendly letter may use contractions, questions and feelings ('I can't wait to see you!'). A formal letter is polite, factual and impersonal: no contractions, slang or rows of exclamation marks, and precise words ('inconvenience', 'request', 'kindly consider'). Never write a formal letter as a list of angry demands; firmness comes from facts.

Worked example

Rewrite in formal tone: 'The canteen food is super bad and we're totally sick of it!!'

Try it first, then show the solutionSolution
  1. Remove slang and contractions.
  2. Replace emotion with a fact.

Answer: 'The quality of food in the school canteen has declined, and several pupils have complained of stale snacks over the past month.'

Opening and closing paragraphs

The first paragraph states the purpose at once. Formal: 'I am writing to bring to your notice ...' / 'I wish to request ...'. Informal: a warm link ('Thank you for your lovely birthday card. I have some exciting news ...'). The closing paragraph rounds off: formal, 'I hope you will take prompt action in this matter.'; informal, 'Give my love to Chachi. Do write soon.' Avoid the stale opening 'I am fine and hope you are also fine'.

Worked example

Write a one-sentence opening for a letter to the Editor about stray cattle on the roads.

Try it first, then show the solutionSolution
  1. State the purpose.
  2. Name the place.

Answer: 'Through the columns of your esteemed newspaper, I wish to draw the attention of the authorities to the danger caused by stray cattle on the main roads of Civil Lines.'

Letter Writing in real life

Each concept, met in an everyday situation. Read the situation, answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Formal complaint that gets results

Suppose the water supply to your building has been irregular for two weeks and your parents decide to write to the Water Board.

What should the letter contain so that the officer can act on it at once?

Try it first, then show the solutionSolution
  1. Exact address and consumer number.
  2. Dates and timings of the problem.
  3. Effect on residents.
  4. A clear, practical request.

Answer: Specific facts and a clear request make a complaint actionable; anger and vague demands do not. That is exactly what the content marks in a formal letter reward.

Memory hook: Facts move files; feelings don't.

Tone fits the reader

Imagine you send the same message about a missed class to your best friend and to your Class Teacher.

How would the two messages differ?

Try it first, then show the solutionSolution
  1. Friend: casual words, contractions, a joke.
  2. Teacher: polite opening, the reason, a request, a courteous close.

Answer: The content is similar but the tone and vocabulary change with the reader. ICSE marks you on choosing the right register.

Memory hook: Who is reading decides how you write.

The layout carries information

Suppose a reply to your letter of request is posted to you but your address had no PIN or house number.

Why does the format matter beyond the examination?

Try it first, then show the solutionSolution
  1. The reply cannot reach you.
  2. Without a date, nobody knows how old the request is.
  3. Without your full name, the office cannot trace you.

Answer: Every part of the format has a real job: address for the reply, date for the record, full name for identification.

Memory hook: No address, no answer.

  • PCS for complaints

    Purpose, Complaint details, Suggestions, then a polite Sign-off.

    Use it when: The four paragraphs of a complaint letter.

Letter Writing: exam-level solved questions

Ordered from exam level to HOTS. Cover the solution, write your own, then compare step by step.

Example 1: Formal complaint with suggestions · 10 marks · Long answerExam level

The public park in your locality has broken swings and no lights, and it has become unsafe for children. Write a letter to the Municipal Commissioner of your city complaining about the problem and offering suggestions.

Try it first, then show the solutionSolution
  1. Full sender's address and date; receiver's designation and address.
  2. 'Dear Sir,' and the purpose in the first paragraph.
  3. Complaint paragraph: two developed points (swings, lighting) with effects.
  4. Suggestions paragraph: at least two practical remedies.
  5. Polite closing, 'Yours faithfully,' and full name.

Answer: B-12, Sunrise Enclave,
Ashok Nagar,
Ranchi – 834 002.
12th January 2027.

The Municipal Commissioner,
Ranchi Municipal Corporation,
Kutchery Road,
Ranchi – 834 001.

Dear Sir,

I am a resident of Sunrise Enclave, Ashok Nagar, and I am writing to bring to your notice the poor condition of the Ashok Nagar Children's Park.

Three of the five swings have broken chains, and the slide has a cracked edge on which a seven-year-old cut his hand last week. Worse, none of the lamp posts has worked since November. After five in the evening the park is completely dark, so parents now keep their children at home, and the park is used by idlers instead.

I would like to suggest that the swings and slide be repaired or replaced at the earliest, and that the lamp posts be fitted with solar lights, which would also save electricity. A board with the park's timings and a helpline number at the gate would help residents report damage quickly. The Residents' Welfare Association is willing to help maintain the park once it is repaired.

I look forward to your prompt action in this matter.

Thanking you,
Yours faithfully,
Aditi Kumari

Example 2: Informal letter: sharing news · 10 marks · Long answerExam level

You have been chosen to represent your school at a state-level debate. Write a letter to your grandfather telling him how you were selected, how you are preparing and how you feel about it.

Try it first, then show the solutionSolution
  1. Friendly layout: address, date, 'Dear Dadu,'.

  4. Affectionate close; first name.

Answer: 27, Model Town,
Ludhiana – 141 002.
5th August 2027.

Dear Dadu,

I hope your knee is better and that you are back to your morning walks. I have news that I know will make you smile.

Last Friday our English teacher held an inter-house debate to choose two speakers for the State Inter-School Debate in Chandigarh. I spoke against the motion that homework should be abolished, and the judges picked me and Harleen from Class X. When Ms Kaur read out my name in assembly, my ears went red!

Since then I have been preparing every evening. I read the newspaper editorial pages, note down facts on index cards and practise in front of Mummy, who times me with her phone. I remember your advice to speak slowly and look at the audience, not at the paper.

I am excited and a little nervous, because the other teams are very experienced. Still, I want to enjoy it and learn as much as I can, whatever the result.

Please bless me. I will call you on the evening of the debate.

Yours lovingly,
Simran

Example 3: Spotting format errors · 5 marks · Short answerHarder exam level

Find five format errors: 'Respected Sir, Subject: Bad roads. I am writing ... Your's sincerely, Arjun' (letter to the Executive Engineer, PWD, with only 'Pune' as the sender's address and '5/3' as the date).

Try it first, then show the solutionSolution
  1. Check the sender's address and date.
  2. Check the salutation and subject line.
  3. Check the subscription and name.

Answer: (1) Incomplete sender's address: house, street, locality and PIN missing. (2) Date '5/3' has no month name or year: '5th March 2027.' (3) 'Respected Sir' should be 'Dear Sir,'. (4) CISCE's format has no subject line. (5) 'Your's sincerely, Arjun' should be 'Yours faithfully,' followed by the full name, e.g. 'Arjun Kulkarni'.

Example 4: Developing a request letter · 6 marks · Short answerHarder exam level

Write the body (three paragraphs) of a letter to your Principal requesting permission to start a Science Club.

Try it first, then show the solutionSolution
  1. Paragraph 1: the request.
  2. Paragraph 2: benefits, with specific activities.
  3. Paragraph 3: practical arrangements and polite close.

Answer: On behalf of the pupils of Class IX, I wish to request your permission to start a Science Club in our school.

Many of us are keen to do experiments beyond the syllabus. The club could build simple models, such as a rain gauge and a solar cooker, hold a monthly quiz and invite a scientist from the university to speak once a term. It would also prepare us for inter-school exhibitions, where our school has not taken part for two years.

Mr Dutta, our Physics teacher, has kindly agreed to guide us. We could meet in the physics laboratory on Saturdays from 11.00 a.m. to 12.30 p.m., and members would pay a small fee for materials. We would be grateful if you would grant us permission and allow us to announce the club in assembly.

Example 5: Choosing the right letter · 3 marks · Short answerHOTS / competency

In the examination you are offered (a) a letter to a friend describing your new school and (b) a letter to the Editor about noise pollution during festivals. You have strong views on noise but find formal format difficult. Which should you choose, and what must you do if you choose (b)?

Try it first, then show the solutionSolution
  1. Choose by content first: which can you develop with specific points?
  2. Format can be learnt; content cannot be faked.

Answer: Choose (b) if you can develop the complaint and suggestions well, because content carries most of the marks; but then you must use the full formal layout: both addresses, 'The Editor, [newspaper]', 'Dear Sir/Madam,', no subject line, 'Yours faithfully,' and full name. If you are unsure of that layout, choose (a) and develop it vividly. Format should be practised in advance so that it never limits your choice.

Example 6: Tone correction · 3 marks · Short answerHarder exam level

Rewrite this informal paragraph so that it could appear in a letter to the Station Master: 'Hey, your trains are always late!! My dad missed his meeting twice. Do something about it, OK?'

Try it first, then show the solutionSolution
  1. Remove greeting slang, contractions and exclamations.
  2. Give facts.
  3. Turn the demand into a polite request.

Answer: 'The 8.15 a.m. local train from Thane has been delayed by more than twenty minutes on most days this month. As a result, many passengers, including my father, have been late for work. I request you to look into the cause of these delays and to announce expected arrival times on the platform.'

Where the marks are

How a typical answer is marked: the value points the examiner looks for and the marks each earns.

Formal letter of complaint with suggestions (board type). CISCE's scheme lists format, content and expression; it does not print marks for each, and Class IX papers are marked by schools, so this split is indicative. (10 marks)

StepMarks
Format: sender's address and date, receiver's designation and address, 'Dear Sir/Madam,', 'Yours faithfully,', full name2
Complaint: at least two developed points with effects3
Suggestions: at least two practical, specific remedies3
Expression: opening and closing sentences, formal tone, grammar and punctuation2

Where students lose marks in Letter Writing

The slips examiners see most often, and what to write instead.

  • Mistake: Mismatched salutation and subscription

    Pupils mix formal and informal conventions, or use forms learnt in lower classes.

    Wrong working

    Respected Madam, ... Yours sincerely, Neha

    Right working

    Dear Madam, ... Yours faithfully, Neha Joshi

    Do this: Learn two pairs only: 'Dear Sir/Madam' + 'Yours faithfully' + full name; 'Dear [relation/name]' + 'Yours affectionately/lovingly' + first name.

    Usually costs: Format marks.

  • Mistake: Incomplete addresses and dates

    Pupils write just a city name, leave out the PIN or the receiver's designation, or write a numeric date.

    Wrong working

    Chennai
    12/1

    Right working

    4, Second Cross Street,
    T. Nagar,
    Chennai – 600 017.
    12th January 2027.

    Do this: Memorise one full address of your own and write it the same way every time.

    Usually costs: Format marks.

  • Mistake: Adding a subject line or putting your name at the top

    Pupils copy layouts from other boards or from office letters.

    Do this: Follow CISCE's published format: no subject line; your name appears only after the subscription.

    Usually costs: Format marks for layout.

  • Mistake: Thin content: repeating the question

    Pupils restate 'there is a problem, please solve it' without details.

    Wrong working

    'The park is in bad condition. Please do something.'

    Right working

    'Three swings have broken chains and the lamp posts have not worked since November, so children cannot play after five.'

    Do this: Two concrete details (where, when, how many, what effect) for every point named in the question.

    Usually costs: Most of the content marks.

  • Mistake: Wrong tone

    Pupils write formal letters as they speak, or make friendly letters stiff.

    Do this: Formal: no contractions, slang or exclamation marks. Informal: natural and warm, but still grammatical.

    Usually costs: Expression marks.

Quick revision checklist

The night before the exam: can you do each of these without looking?

  • Can you write your full address and today's date in CISCE style without thinking?
  • Can you name the correct salutation and subscription pair for formal and informal letters?
  • Can you write the receiver's block for a Principal, an Editor and a Municipal Commissioner?
  • Can you turn a vague complaint into two specific details?
  • Can you give two practical suggestions for any civic problem?
  • Can you rewrite an informal sentence in formal tone?

Letter Writing: frequently asked questions

Is the Class IX letter different from the Class X letter?

No. CISCE prints one English Paper 1 syllabus for Classes IX and X. Your school sets and marks the Class IX paper, but the formats and the expectations are the same.

Should I use block or indented format?

Either. CISCE's format document shows both and says 'Any one format may be followed, all are acceptable.' Use one consistently.

Is 'Thanking you' compulsory?

No. CISCE's sample uses 'Thanking you,' before 'Yours faithfully,', but a letter without it is not wrong.

How long should the letter be?

No word limit is printed. Four or five well-developed paragraphs, roughly 150-200 words in the body, cover the points comfortably in 20 minutes.
