Letter Writing for Govt Exams: Format, Types and Samples
This article is a complete, exam-ready guide to letter writing for the descriptive papers of banking, insurance, SSC-type, State PSC, defence and school-level exams. It covers the full formal letter format from sender's address to enclosure, the informal letter format, the formal-informal-semi-formal comparison, all the main types of formal letters, salutation and sign-off charts, subject line rules, ready-made sentence templates, and four complete model letters written to a bank manager, a newspaper editor, a municipal officer and a friend. Every rule comes with a fixed formula, a correct and a wrong example, and a memory trick that even a beginner in English can use.

Introduction
A letter is a written message from one person to another. It follows a fixed order of parts. That fixed order is what exams test.
People often say letters are outdated. For exams, the opposite is true.
- Formal letters are still everywhere. Offices, banks, schools and government departments run on them.
- The format transfers. Once you know a letter, email writing is almost the same task with two parts removed.
- It is a scoring topic. The marks sit in the structure, not in your vocabulary.
Descriptive papers usually ask for a letter of about 150 words. You will be told whether it is formal or informal, or you will have to judge it from the situation. That single judgement decides half your marks.
Where This Topic Is Asked
| Exam Group | How This Topic Appears | Rough Weight | What You Must Practise |
|---|---|---|---|
| Bank and insurance officer exams | A typed descriptive paper right after the objective test. Letter writing appears with essay, precis or email, depending on the year's pattern. | 25 to 50 marks for the full descriptive paper | A 150-word letter finished in 12 to 15 minutes, typed on a computer. |
| SSC-type descriptive papers | Where a descriptive paper is held, the letter is about 150 words with a 10 per cent margin, along with an essay of about 250 words. | Combined with the essay in one paper | Handwritten speed and neat, correct format. Note that SSC CGL no longer holds a descriptive paper. |
| State PSC mains and judiciary | Direct questions on official correspondence, often addressed to a named authority, with a printed word limit. | Varies by state | Official tone and staying inside the word limit exactly. |
| Defence and police service exams | Letters to authorities appear inside the descriptive language paper. | Part of a larger descriptive paper | Formal structure with no personal emotion anywhere. |
| School and board-level exams | Both formal and informal letters are asked directly, and this section is among the highest-scoring parts of the paper. | Often 10 to 15 marks | Both formats, because either one can be set. |
| Interview and job stage | Applications, resignations and official requests are written for real. | A career-long skill | Everything in this article, used at work. |
Before you start, confirm from the exam-wise syllabus hub whether your paper has a descriptive section at all. If it does, this is one of the safest topics you can prepare, because the format alone carries a large share of the marks, whatever the topic of the letter is.
Concept in Simple Words
A letter has a sender, a receiver and a purpose. Everything in the format exists to make those three clear.
Think of the four written formats as one family.
- A letter is the oldest and the most complete. It carries addresses, a date and a formal close.
- An email is a letter with two parts removed: the postal addresses and the date. Learn it in email writing.
- A report is a factual write-up of an event, with no salutation at all. Learn it in report and paragraph writing.
- A precis is a shortened version of a passage that somebody else wrote. Learn it in precis writing.
The Three Kinds of Letters
Every letter question falls into one of three boxes: formal, semi-formal and informal. Identify the box before you write anything.
| Point of Difference | Formal Letter | Semi-Formal Letter | Informal Letter |
|---|---|---|---|
| Also called | Official letter | Business-personal letter | Unofficial or personal letter |
| Written to | A bank manager, an editor, a principal, an officer, a company | A team member, a colleague, a known senior, a distant acquaintance | A friend, a parent, a sibling, a relative |
| Subject line | Compulsory | Usually written | Not written at all |
| Receiver's address | Written inside the letter | Written inside the letter | Written only on the envelope |
| Salutation | Dear Sir, Dear Madam, Dear Mr Rao | Dear Ms Nair, Dear Anil | My dear Meena, Dear Papa, Hi Ravi |
| Tone | Polite, official, impersonal | Polite but warmer | Friendly, personal, emotional |
| Length | Short and to the point | Short | Depends on the news and the relationship |
| Sign-off | Yours faithfully, Yours sincerely | With regards, Best regards | Lots of love, Yours affectionately, Best wishes |
One warning from past papers. The same receiver can need a different type of letter.
- A letter to your principal asking for leave is a formal letter.
- A letter to the same principal after many years, to catch up is an informal letter.
So do not decide by the receiver's designation. Decide by the purpose of the letter.
Formula Box
- Formal letter = Sender's address + Date + Receiver's designation and address + Subject + Salutation + Body + Complimentary close + Name and designation
- Informal letter = Sender's address + Date + Salutation + Body + Sign-off + Name
- Body of any letter = Introduction (purpose) + Middle (details and reasons) + Conclusion (what you want)
- Subject line = purpose in 6 to 8 words, in a formal letter only
- Length = about 150 words, unless the question prints another limit
- Time plan = 2 minutes planning + 10 minutes writing + 3 minutes checking
Formal Letter Format, Part by Part
The Twelve Parts of a Formal Letter
Write the parts in this order. The order never changes, whatever the topic is.
| Component | What to Write | Sample Line | Common Mistake | Marks Impact |
|---|---|---|---|---|
| 1. Sender's address | Your own address at the top left. Also called the return address. House or door number, street, city, state and PIN code. Never write your own name here. | 24, Second Street, Saibaba Colony, Coimbatore 641011 | Writing your name above the address, or skipping the PIN code. | High. It is the first block the examiner sees. |
| 2. Date | The date on which you write the letter, placed just below your address. Use one clear format and stay with it. | 12 September 2026, or 12/09/2026 | Leaving the date out. In a letter the date is compulsory, unlike in an email. | High. A missing date is an obvious and easy loss. |
| 3. Receiver's designation | The name and designation of the person who will read it. Use the designation given in the question. | The Branch Manager | Writing only "To Sir" with no designation, which leaves the reader unnamed. | High. This tells the examiner you read the question. |
| 4. Receiver's address | The organisation name and full address below the designation, with the PIN code. | Example Bank, Ambattur Branch, Chennai 600053 | Mixing the sender's and receiver's addresses, or placing the receiver's address above the date. | High. Order errors here are heavily marked. |
| 5. Subject | The purpose of the letter in 6 to 8 words. A strong subject conveys the whole letter at a glance. | Subject: Request for information on education loan schemes | Writing a long sentence, or leaving the subject out in a formal letter. | Very high. The subject is often the first thing scored. |
| 6. Salutation | The greeting. Use the name if you know it, otherwise Sir or Madam. | Dear Sir, or Dear Mr Rao, | Using "Hi" or "Hey" in a formal letter, or writing "Respected Sir, with due respect I beg to say". | High. Tone marks begin at this line. |
| 7. Body: introduction | State who you are and why you are writing, in the first two sentences. Come to the point at once. | I am a savings account holder at your branch, and I am writing to seek information about your education loan schemes. | Spending the whole first paragraph on greetings and background. | High. A clear purpose sentence carries real marks. |
| 8. Body: middle | The supporting details: dates, numbers, reference numbers, reasons, and why the matter is important. | My daughter has secured admission to a four-year engineering course beginning in July 2026. | Mixing two unrelated matters, or writing details with no facts in them. | Highest. This is the largest part of the letter. |
| 9. Body: conclusion | State the action you expect, and close with a courteous line of thanks or request. | I request you to send the details of eligibility, interest rates and documents required. | Ending with no request, so the reader does not know what to do. | High. A letter with no action point is treated as incomplete. |
| 10. Complimentary close | The polite closing phrase, aligned with the salutation you used. | Yours faithfully, or Yours sincerely, | Mixing a formal greeting with a casual close such as "Bye" or "Thanks". | High. This pairing is a standard checking point. |
| 11. Signature and name | Leave a line for the signature, then write your full name below it. | (Signature) Ravi Kumar | Forgetting the name, or signing with initials only. | High. An unnamed letter looks unfinished. |
| 12. Designation and enclosure | Add your designation if you hold one. If any document goes with the letter, list it under the word Enclosure. | Enclosure: Copy of admission letter | Attaching a document in the question and never mentioning it in the letter. | Medium to high. An unmentioned enclosure loses easy marks. |
Exam Alert
- Sender's address first, receiver's address after the date. Reversing them is the most common format error.
- The date is compulsory in a letter. This is the opposite of an email, where the system adds it.
- No subject line in an informal letter. Adding one there is also an error.
- Never use short forms, slang or colloquial words anywhere in a formal letter.
- A weak subject line and a mismatched sign-off are the two errors examiners spot fastest.
Informal Letter Format
The informal letter is shorter in structure and warmer in tone. Five parts are enough.
| Component | What to Write | Sample Line | Common Mistake | Marks Impact |
|---|---|---|---|---|
| 1. Sender's address | Your address at the top left. The receiver's address is written only on the envelope, never inside the letter. | 18, Anna Nagar, Madurai 625020 | Writing the friend's address inside the letter, which belongs to the formal format. | High. This one difference is tested often. |
| 2. Date | The same as in a formal letter, written below your address. | 12 September 2026 | Skipping the date because the letter is personal. | Medium to high. It is still a format element. |
| 3. Salutation | A warm greeting with the first name, nickname or relationship. | My dear Meena, / Dear Papa, / Hi Ravi, | Writing "Dear Sir" to a friend, which breaks the tone completely. | High. Tone is judged from this line onwards. |
| 4. Body | Open with a personal line, then share the news, feelings, advice or experience. The body may be longer and more detailed than in a formal letter. | I hope everyone at home is well. I have wonderful news to share with you. | Writing in stiff official language, which makes a personal letter sound like a notice. | Highest. Warmth and natural flow are marked here. |
| 5. Sign-off and name | A personal closing phrase, then your first name. There is no single fixed phrase. | Lots of love, Priya / With best wishes, Anil | Closing with "Yours faithfully", which belongs to a formal letter. | High. The wrong sign-off undoes an otherwise good letter. |
Quick Facts
- Informal letters have no subject line and no receiver's address inside the letter.
- No strict format is imposed, but the address, date, salutation, body and sign-off are still expected.
- Friendly language is allowed, and extra personal information is welcome.
- Formal letters are the opposite: short, precise and strictly to the point.
Salutation and Sign-Off Chart
Pick one row and stay inside it. Mixing rows is a tone error.
| Situation | Salutation | Complimentary Close | Where It Is Used |
|---|---|---|---|
| Name not known | Dear Sir, / Dear Madam, / Dear Sir or Madam, | Yours faithfully, | Letters to a bank, an editor, a department, a company. |
| Name known | Dear Mr Rao, / Dear Ms Nair, / Dear Dr Iyer, | Yours sincerely, | Letters to a named officer, manager or professor. |
| Position known, name not known | Dear Sir, with the designation written above the address | Yours faithfully, | Letters to the Principal, the Commissioner, the Editor. |
| Colleague or team | Dear Anil, / Dear Team, | With regards, / Best regards, | Semi-formal letters and internal notes. |
| Friend or relative | My dear Meena, / Dear Papa, / Hi Ravi, | Lots of love, / Yours affectionately, / Best wishes, | Informal and personal letters. |
Remember the pairing in one line. Name unknown goes with faithfully. Name known goes with sincerely. This single pairing rule appears in exam after exam.
Types of Formal Letters
All formal letters share one format. Only the purpose of the body changes. These are the types that appear most often.
| Type | Purpose | Typical Exam Question |
|---|---|---|
| Business letter | Official communication inside a company or between companies. | Placing an order with a publisher for books. |
| Official letter | Communication with a government office, a bank or an authority. | Writing to the Municipal Commissioner about waste disposal. |
| Social or circular letter | Passing information to a group, such as a notice in a housing society. | Informing residents about a change in water supply timings. |
| Inquiry letter | Seeking information or clarification about a service or product. | Asking a bank about education loan schemes. |
| Complaint letter | Reporting dissatisfaction with a product, a service or a civic problem. | Complaining about a damaged delivery or poor street lighting. |
| Application letter | Applying for a job, a scholarship, admission or leave. | Applying to the Principal for three days of leave. |
| Cover letter | Sent with a resume to introduce yourself and your qualifications. | Applying for an advertised post in a company. |
| Permission letter | Formally requesting authorisation to do something. | Seeking permission to organise a cultural festival on the school premises. |
| Recommendation letter | Written by a teacher or employer to endorse someone's ability or character. | Recommending a student for a scholarship. |
| Resignation letter | Informing an employer of your decision to leave, with the notice period. | Resigning from a post with effect from a stated date. |
| Invitation letter | Inviting someone to an event, with date, time and venue. | Inviting a guest to a seminar or annual function. |
| Letter to the editor | Raising a public issue in a newspaper and suggesting solutions. | Writing about air pollution or the importance of blood donation. |
| Thank-you and apology letters | Expressing gratitude for help received, or regret for a mistake. | Thanking an organisation for support, or apologising for a delay. |
| Condolence letter | Expressing sympathy on a loss or bereavement. | Writing to a colleague on the loss of a family member. |
Quick Facts
- One format, many purposes. All these types use the same twelve parts. Only the body changes.
- Most asked in exams: inquiry, complaint, application, permission and letter to the editor.
- Letters to authorities almost always expect suggested remedies, not just the problem.
- Employment letters need one extra element: a stated date, such as the notice period or the date of joining.
Subject Line: Weak Versus Strong
The subject line is small, but it decides the examiner's first impression. Compare these pairs.
| Situation | Weak Subject Line | Strong Subject Line |
|---|---|---|
| Asking a bank about a loan | Subject: Loan | Subject: Request for details of education loan schemes |
| Reporting uncollected garbage | Subject: Complaint | Subject: Complaint regarding irregular waste collection in Ward 12 |
| Applying for leave | Subject: Leave | Subject: Application for leave from 12 to 14 September 2026 |
| Writing to a newspaper | Subject: Air pollution problem in our city and what should be done about it | Subject: Rising air pollution and possible remedies |
| Asking to hold an event | Subject: Permission please | Subject: Permission to hold the annual cultural festival |
| Changing address in records | Subject: Address | Subject: Request to update residential address in policy records |
The pattern is always the same: action word + exact matter + a number or date if the question gives one. Keep it between 6 and 8 words, and never end it with a full stop.
Model Letter 1: Inquiry Letter to a Bank Manager
Question: Write a letter to the manager of a local bank requesting information about education loans for higher studies.
24, Second Street
Saibaba Colony
Coimbatore 641011
12 September 2026
The Branch Manager
Example Bank, Gandhipuram Branch
Coimbatore 641012
Subject: Request for details of education loan schemes
Dear Sir,
I hold a savings account at your branch and I am writing to seek information about the education loan schemes offered by the bank.
My daughter has secured admission to a four-year engineering course that begins in July 2026. The annual fee, along with hostel charges, comes to about four lakh rupees. I would like to know the loan amount available for such a course, the applicable interest rate, the repayment period, and whether any margin money or collateral is required.
I request you to send the eligibility conditions and the list of documents required, or to inform me of a convenient time to visit the branch. An early reply would help me complete the admission formalities on time.
Thank you for your assistance.
Yours faithfully,
Ravi Kumar
Account No. 3391XXXX
Model Letter 2: Letter to the Editor
Question: Write a letter to the editor of a local newspaper expressing concern about rising air pollution in your city and suggesting measures.
18, Anna Nagar
Madurai 625020
12 September 2026
The Editor
The City Herald
Madurai 625001
Subject: Rising air pollution and possible remedies
Dear Sir,
Through the columns of your newspaper, I wish to draw the attention of the authorities and the public to the worsening air quality in our city.
Traffic has grown sharply on the arterial roads, and construction dust is now visible in residential areas throughout the day. Residents near the bypass report frequent throat irritation, and elderly people and young children are the worst affected. Open burning of garbage in vacant plots adds to the problem every evening.
A few practical steps would help. The corporation could increase the frequency of city buses on busy routes, enforce the covering of construction material, penalise open burning, and take up tree plantation along the bypass. Residents, on their part, could share vehicles for daily travel.
I hope the publication of this letter will encourage early action.
Yours faithfully,
Priya Nair
Model Letter 3: Complaint Letter to a Civic Authority
Question: Write a letter to the Municipal Commissioner about improper waste disposal in your locality and suggest solutions.
7, Lake View Road
Ward 12, Nagpur 440010
12 September 2026
The Municipal Commissioner
Municipal Corporation
Nagpur 440001
Subject: Complaint regarding irregular waste collection in Ward 12
Dear Sir,
I wish to bring to your notice the irregular collection of household waste in Ward 12 over the past two months.
The collection vehicle now visits the locality twice a week instead of daily. As a result, waste is dumped at the corner of Lake View Road and remains there for several days. Stray animals scatter it across the road, and residents living nearby have complained of a persistent smell and of mosquitoes breeding in the wet waste.
I request you to restore daily collection, place covered bins at the two main junctions, and depute a supervisor to inspect the locality once a week. Residents are willing to cooperate with a segregation drive if the corporation announces one.
I shall be grateful for your early intervention in this matter.
Yours faithfully,
Anil Deshmukh
Secretary, Ward 12 Residents' Association
Model Letter 4: Informal Letter to a Friend
Question: Write a letter to your friend describing a place you visited recently.
18, Anna Nagar
Madurai 625020
12 September 2026
My dear Meena,
I hope you and everyone at home are keeping well. I have been meaning to write to you ever since I returned from my trip last month.
We spent four days in Munnar, and I still cannot get the place out of my head. The tea gardens run along the slopes like green steps, and the mist comes down so low in the morning that you can barely see the next hill. We walked through a tea factory, watched the leaves being dried and rolled, and came back with two packets for you. On the last day we started at five in the morning to see the sunrise from the top road, and the cold was worth every minute of it.
Do plan to come with us next time. Your parents would enjoy it too, and the drive from your side is only six hours.
Write back soon and tell me how your new job is going.
Lots of love,
Priya
Exam Alert
Whatever the topic, an examiner checks the same six things in every letter. Tick them off before you move to the next question.
- Correct type chosen: formal or informal, judged from the purpose.
- Address and date blocks in the right order and the right places.
- Subject line present and specific, in a formal letter only.
- Salutation and close taken from the same row of the chart.
- Three-paragraph body: purpose, details, action.
- Name and designation at the end, with an enclosure line if needed.
Ready-Made Sentence Templates
These are fill-in-the-blank lines. Learn them once, and you will never sit blank in the exam hall. Join the sentences with linking words from sentence connectors, and shorten long phrases using one-word substitution when the word limit gets tight.
| Where It Goes | Template Line | How to Fill It |
|---|---|---|
| Subject line | Subject: Request for ______ / Complaint regarding ______ / Application for ______ / Permission to ______ | Pick the action word first, then the exact matter, then a date or number. |
| Opening, request letter | I am writing to request ______. | State the purpose in the very first sentence. |
| Opening, complaint letter | I wish to bring to your notice ______. | Name the problem and the place at once. |
| Opening, letter to the editor | Through the columns of your newspaper, I wish to draw attention to ______. | This is the standard opening. Learn it word for word. |
| Self-introduction | I am ______, a ______ of ______. | Name, then your relation to the receiver: account holder, resident, student, customer. |
| Detail sentence | The position is as follows: ______, ______ and ______. | Give facts with dates and numbers, not general statements. |
| Suggestion sentence | A few practical steps would help: ______, ______ and ______. | Use this in letters to authorities and editors, where remedies are expected. |
| Action sentence | I request you to ______ at the earliest. | One clear action, and a date if the question gives one. |
| Closing courtesy | I shall be grateful for your early intervention. / Thank you for your assistance. | One line only, then the complimentary close. |
| Enclosure line | Enclosure: ______ | Name the document: copy of admission letter, invoice, medical certificate. |
Tone and Style Rules
| Rule | What to Do | Sample Line | Common Mistake | Marks Impact |
|---|---|---|---|---|
| Be polite, always | Stay courteous even in a complaint. Make the point firmly, but never rudely. | I request you to restore daily collection at the earliest. | Angry or accusing lines such as "your department is completely careless". | Very high. Impolite wording is penalised directly. |
| Come to the point at once | State the purpose in the first two sentences of the body. | I am writing to seek information about your education loan schemes. | Long background before the reader learns why you wrote. | High. Formal letters are marked for directness. |
| Keep it short | Around 150 words for a formal letter, in three short paragraphs. | Three paragraphs of three or four sentences each. | Writing a 350-word letter, or writing four lines and stopping. | High. Both extremes lose marks. |
| No slang or short forms | Write full words. No plz, asap, u, etc., and no emoticons or symbols. | Please reply at the earliest. | Chat language carried over from messaging apps. | Very high. One casual word can pull down the tone score. |
| State facts, not invented details | Use only what the question gives, and add reasonable detail that fits it. | Collection has fallen to twice a week over the past two months. | Inventing dramatic figures or events that the question never mentioned. | High. False or exaggerated content reads as padding. |
| Suggest, do not order | When you propose a remedy, use suggesting words, not commanding ones. | The corporation could increase the frequency of buses. | "You must do this immediately" written to a senior authority. | High. Tone is central in letters to authorities. |
| Correct tense and voice | Past tense for what happened, present for the current situation. Prefer active voice. Revise tenses and active and passive voice. | The vehicle stopped coming daily, and waste now lies on the roadside. | Mixing tenses inside one paragraph with no reason. | High. Tense slips are easy to spot in a 150-word answer. |
| Proofread at the end | Check spelling, capital letters and full stops. Keep three minutes for this. | Fixing "recieve" to "receive" before time ends. | Adding more content in the last three minutes instead of checking. | Medium to high. Practise with commonly misspelt words. |
Formal Word Bank: Spoken English to Letter English
Most students already know what to say. They lose marks because the words are too casual. Swap the left column for the right column.
| What Students Write | What a Letter Needs | Example in a Letter |
|---|---|---|
| I want to tell you | I wish to bring to your notice | I wish to bring to your notice the delay in delivery. |
| Please do it fast | Kindly expedite the matter, at the earliest | Kindly expedite the repair work at the earliest. |
| There is a big problem here | The following difficulty has arisen | The following difficulty has arisen in our locality. |
| I need an answer soon | An early reply would be appreciated | An early reply would be appreciated, as admission closes on 30 June. |
| I am sending the papers | The documents are enclosed for your reference | The admission letter is enclosed for your reference. |
| Sorry for the trouble | I regret the inconvenience caused | I regret the inconvenience caused by the delay. |
| Thanks a lot | I shall be grateful, thank you for your assistance | I shall be grateful for your early intervention. |
| Kindly do the needful | Kindly sanction the leave, kindly restore the service | Kindly sanction three days of leave from 12 September. |
| As per my knowledge | To the best of my knowledge | To the best of my knowledge, the fee was paid in May. |
| Waiting for your reply | I look forward to your response | I look forward to your response at your convenience. |
Two habits help here. Keep a small notebook of these swap pairs and revise it with commonly confused words. And keep idioms out of a formal letter, however well you know them, because they make an official message sound casual. Save them for the objective paper, where idioms and phrases are asked directly.
Key Highlights
- Polite beats forceful. A courteous complaint scores higher than an angry one, every time.
- Facts beat adjectives. "Collection fell to twice a week" is stronger than "the service is terrible".
- Every formal letter ends with an action. If the reader cannot tell what to do, the letter is incomplete.
- Enclosure, not attachment. Letters enclose documents. Only emails attach files.
- Choosing the wrong letter type costs more marks than any grammar mistake in the paper.
Fifteen-Minute Answer Plan for the Exam Hall
- Minute 1: Decide the type. Ask one question: is the purpose official or personal? That answers formal or informal.
- Minute 2: Note four things from the question: who you are, who the receiver is, the purpose, and any date, number or document mentioned.
- Minutes 3 and 4: Write the address, date, receiver's block, subject and salutation. Your format marks are now safe.
- Minutes 5 to 12: Write the three body paragraphs: purpose, details, action.
- Minute 13: Add the complimentary close, name, designation and enclosure line.
- Minutes 14 and 15: Proofread. Check the salutation and close pair, the tense, and any casual word that slipped in.
Worked Examples: Wrong to Right
Example 1 (choosing the wrong type)
Sentence: The question says: write to your Principal asking for three days of leave. The student begins: "My dear Sir, hope you are doing great!"
Trap: The student knows the Principal personally, so a warm greeting feels natural and respectful. The purpose is official, so the letter must be formal, whatever the personal equation is.
Correct Answer: Dear Sir, ... Subject: Application for leave from 12 to 14 September 2026.
Rule in Simple Words: Decide by the purpose, not by the person. Official purpose means a formal letter.
Example 2 (address blocks reversed)
Sentence: The Branch Manager, Example Bank, Coimbatore ... then the student's own address ... then the date.
Trap: Envelopes carry the receiver's address first, so students copy that habit into the letter. Inside a letter the order is fixed and different.
Correct Answer: Sender's address, then the date, then the receiver's designation and address.
Rule in Simple Words: You first, date next, receiver after. The receiver's address always comes after the date.
Example 3 (subject line in an informal letter)
Sentence: My dear Meena, Subject: About my trip to Munnar.
Trap: A subject line looks organised, and students carry it across from the formal format. An informal letter never has one, so this is a format error even though the letter reads well.
Correct Answer: Remove the subject line. Start the body straight after the salutation.
Rule in Simple Words: Subject line in formal letters only. Never in a personal letter.
Example 4 (salutation and close mismatch)
Sentence: Dear Mr Rao, ... Yours faithfully, Ravi Kumar
Trap: Both parts are correct formal English on their own, so nothing looks wrong. The name is known here, so the close should be sincerely, and the pairing rule is checked in almost every paper.
Correct Answer: Dear Mr Rao, ... Yours sincerely, Ravi Kumar
Rule in Simple Words: Name known means sincerely. Name unknown means faithfully.
Example 5 (rude tone in a complaint)
Sentence: Your department is totally careless and nobody there does any work at all.
Trap: The frustration is real, and students believe strong words show seriousness. A letter is marked on courtesy, and an insulting line cancels the value of a valid complaint.
Correct Answer: Waste collection has fallen to twice a week over the past two months, which has caused a persistent problem in the locality.
Rule in Simple Words: State the fact, not the insult. Be firm, stay polite.
Example 6 (old-fashioned begging language)
Sentence: Respected Sir, with due respect I beg to state that your good self may kindly do the needful.
Trap: These phrases appear in old letter guides and sound very respectful. They are outdated, and none of them names the action you actually want.
Correct Answer: Dear Sir, I request you to sanction three days of leave from 12 September 2026.
Rule in Simple Words: Modern formal English is simple and direct. Name the action clearly.
Example 7 (no action point)
Sentence: The waste is not being collected regularly and residents are suffering a lot. Thank you.
Trap: The problem is described clearly, so the letter feels complete. The reader still does not know what is being asked: more vehicles, new bins, or an inspection.
Correct Answer: I request you to restore daily collection, place covered bins at the two junctions, and depute a supervisor for a weekly inspection.
Rule in Simple Words: Every formal letter must end with a clear request for action.
Example 8 (word limit ignored)
Sentence: A 400-word letter written for a 150-word question.
Trap: More content feels like more marks, especially when the topic is familiar. Length control is part of the skill being tested, and a long letter usually repeats itself.
Correct Answer: Cut it to three paragraphs: purpose, details, action. Remove repeated sentences and long background.
Rule in Simple Words: Stay close to the printed limit. A ten per cent margin is normally safe.
Common Traps Students Fall Into
These are the habits that most often cost marks. Each one is a common trap, not a silly mistake, and each has a one-line fix. Several are tested in the objective paper too, so read this list alongside error spotting practice.
- Wrong: "Kindly do the needful." Correct: "Kindly sanction the leave and inform me by post." — A request must name the exact action.
- Wrong: "Kindly revert back soon." Correct: "Kindly reply soon." — Revert already means to come back.
- Wrong: "Myself Ravi Kumar, writing this letter." Correct: "I am Ravi Kumar, a resident of Ward 12." — Myself Ravi is not English.
- Wrong: "Your good self is requested to look into it." Correct: "I request you to look into the matter." — Your good self is not standard English.
- Wrong: "I want to discuss about the delay." Correct: "I want to discuss the delay." — Discuss already carries the meaning of "about".
- Wrong: "Please find the attached herewith my certificate." Correct: "The certificate is enclosed for your reference." — In a letter, documents are enclosed, not attached.
- Wrong: "The meeting was preponed to Monday." Correct: "The meeting was advanced to Monday." — Prepone is Indian usage and is not accepted in formal writing.
- Wrong: "I am having two documents to submit." Correct: "I have two documents to submit." — Have for possession is not used in the continuous form.
- Wrong: "Same is submitted for your kind approval." Correct: "The application is submitted for your approval." — Begin with a proper subject, not with same.
- Wrong: "Thanking you in anticipation, ur's faithfully." Correct: "Thank you. Yours faithfully," — One close only, spelled in full, with no short forms.
- Wrong: Writing the sender's name above the sender's address. Correct: The address alone goes at the top, and your name goes at the end, below the close.
Memory Tricks and Formulas
1. ADDRESS BS: the formal letter order
Say the parts as one chain: Address, Date, Designation, Receiver's address, Subject, Salutation, then Body and Sign-off. Remember the picture of writing your own address first and travelling down the page to the receiver.
2. Faithfully for unknown, Sincerely for known
Both start with the same letter as the clue. F for faithfully goes with a faceless reader whose name you do not have. S for sincerely goes with a specific named person. This one pairing appears in exam after exam.
3. PDA: the three body paragraphs
PDA means Purpose, Details, Action. Remember Please Draft Accurately. If any of the three is missing, the letter is incomplete, however good the language is.
4. Purpose decides the type
Never decide formal or informal by looking at the receiver. Ask one question: is the purpose official or personal? A letter to your own uncle asking for a job reference is formal. A letter to your Principal after ten years is informal.
5. The 6 to 8 word subject rule
Keep the subject line between 6 and 8 words. Start with an action word: Request, Complaint, Application, Permission, Invitation. Then add the exact matter, with a date or number if the question gives one. And remember: subject line in formal letters only.
6. The 150 and 3 rule
Aim for about 150 words in 3 paragraphs. That works out to four or five sentences per paragraph. If the question prints another limit, that limit wins.
7. The four bans
Before you submit, check four bans: no slang or short forms, no rude words, no invented facts, no missing action point. Weak-English students who check only these four move up several marks, because these are exactly what examiners look for.
8. Envelope versus letter
The receiver's address goes inside a formal letter, but only on the envelope for an informal one. Picture the postman: for a personal letter he needs the address, but your friend does not.
Exam Patterns and High-Yield Facts
Frequently Confused Pairs
| Pair | How They Differ | Mini Trick |
|---|---|---|
| Formal vs Informal letter | Formal has a subject line, the receiver's address inside, and an official tone. Informal has none of these and is personal in tone. | Subject line present means formal. |
| Letter vs Email | A letter carries postal addresses and a date line. An email carries a subject line, and the system adds the date. | Letter has a date, email has none. |
| Letter vs Report | A letter greets a reader and asks for something. A report states facts about an event with no greeting. | Letter greets, report does not. |
| Yours faithfully vs Yours sincerely | Faithfully is used when the name is not known. Sincerely is used when it is. | F for faceless, S for specific. |
| Application vs Complaint letter | An application asks for something to be granted. A complaint reports a problem and asks for it to be fixed. | Application requests, complaint reports. |
| Inquiry vs Order letter | An inquiry asks for information before deciding. An order places a confirmed request for goods. | Inquiry asks, order buys. |
| Cover letter vs Resume | The cover letter introduces you and explains your interest. The resume lists your qualifications and experience. | Letter explains, resume lists. |
| Enclosure vs Attachment | Documents sent with a letter are enclosed. Files sent with an email are attached. | Paper is enclosed, files are attached. |
| Letter to the editor vs Essay | A letter raises a public issue in letter format and asks for action. An essay argues a topic in continuous paragraphs with no address block. | Letter is addressed, essay is not. |
| Semi-formal vs Formal | Semi-formal keeps the structure but relaxes the tone, and is used with people you already know at work. | If you would use the first name in speech, semi-formal fits. |
Repeating Question Patterns
- Letters to a bank or insurance office are the most repeated in officer-level papers: education loans, address changes in records, cheque book requests, wrong deductions and account queries. A little banking awareness makes these letters easier to fill with correct detail.
- Letters to civic authorities come next: waste disposal, water supply, street lighting, road repair, public transport and park cleanliness, always with suggested remedies.
- Letters to the editor are a fixed favourite: air pollution, traffic, blood donation, road safety, misuse of public spaces, and the value of a civic habit. Passages on these themes also appear in reading comprehension.
- Letters to a principal or director appear at school and clerical level: leave, library facilities, permission for an event, new subjects in the curriculum, and fee corrections.
- Employment letters are common: job applications with a resume, resignation with a notice period, and requests for a certificate or a relieving letter.
- Informal letters repeat on four themes: describing a place you visited, congratulating a friend, giving advice to a younger relative, and sharing news about a result or a new job.
Exam-Wise Focus
- Bank and insurance officer exams: The descriptive paper is typed right after the objective test. Prepare letters together with precis writing and situation analysis, and confirm the year's pattern from the official notification.
- SSC-type descriptive papers: Where they are held, the letter is about 150 words with a 10 per cent margin. Practise handwriting speed as well as format.
- State PSC mains and judiciary: Official correspondence with a printed word limit, usually addressed to a named authority. Practise cutting the same letter to 120 words without losing the action point.
- Defence and police service exams: Formal letters to authorities, where a neutral tone and strict structure matter more than style.
- School and board exams: Both formats are set, and this section is among the highest-scoring in the paper. Learn the informal format as carefully as the formal one.
- Objective papers: No letter question, but the same grammar decides your marks. Support this topic with subject-verb agreement and punctuation rules.
- Interview and document stage: Applications, resignation letters and requests for certificates are written for real, and a clean format creates a good first impression before you enter the room.
Practice Set: Write These This Week
Reading this article once will not build the skill. Writing ten letters will. Give each one 15 minutes and a 150-word limit.
- To the manager of a bank, asking for details of an education loan for higher studies.
- To an insurance office, requesting a change of residential address in your policy records.
- To the Municipal Commissioner, about improper waste disposal in your locality, with suggestions.
- To the editor of a newspaper, about rising air pollution in your city and possible remedies.
- To the editor of a newspaper, on the importance of voluntary blood donation.
- To the Principal of your school or college, requesting better library facilities.
- To a local government official, requesting improvements to public transport in your area.
- To the Deputy Commissioner of Police, reporting a rise in thefts in your area and suggesting steps.
- To a company, complaining about a damaged product and asking for a replacement.
- To a friend, describing a place you visited recently, or congratulating them on a new job.
After each letter, check only six things.
- Did you choose the correct type, formal or informal?
- Are the address and date blocks in the right order?
- Is the subject line specific, and present only in a formal letter?
- Do the salutation and close match?
- Does the body follow purpose, details, action?
- Is the letter close to 150 words?
Then test the objective side with the free English MCQ quizzes, and if your descriptive paper is typed, build speed on the typing test page, because format and typing together decide whether you finish in time.

Letter writing is one of the few topics where a student weak in English can score close to full marks, because the structure carries the answer. So write two letters from the practice set every week and check them against the format tables above. Then strengthen the areas examiners notice most through the wider topic-wise English notes and a stock of exact words from synonyms and antonyms. Letters to editors and authorities also need current examples, so add ten minutes of daily current affairs reading, attempt a full paper from the mock test archive, and keep an eye on the latest government job notifications so you never miss a deadline for the real applications you will write.
