Informal Letter Writing — Personal Correspondence

Informal Letter Writing — Personal Correspondence

Informal letters are, on the surface, the easiest genre in this book — you already know how to write to someone you love. But exams test informal letters precisely because "easy" and "well-executed" are not the same thing. A candidate who has spent months perfecting the rigid format of official correspondence often overcorrects into stiffness when asked to write to a friend, producing something that reads like a formal letter with "Dear" swapped for a first name. This chapter shows you how to keep the warmth genuine while still satisfying an examiner's checklist, and gives you five model letters covering the situations most commonly asked: a letter to a friend, a letter to a parent, a letter to a sibling, a congratulatory letter, and a letter of condolence or comfort.

What Makes a Letter "Informal," and What Doesn't Change

Informal does not mean formless. Even a letter to your closest friend has a recognisable shape: your address and the date at the top, a warm salutation, a body organised into paragraphs that move somewhere (not a single unbroken block of feeling), a closing that matches your relationship to the recipient, and a signature — usually just your first name. What changes from formal letters is the register: contractions are fine ("I've", "didn't"), sentences can be shorter and more conversational, and you are free to ask about the recipient's life, share opinions, joke, or express emotion directly. What does not change is that the letter should still have a clear reason for existing — news to share, a favour to ask, an occasion to mark — even if that reason is folded into affectionate conversation rather than announced in a subject line.

Format, Element by Element

1. Sender's address. Top left, as in formal letters, though in an informal letter it is acceptable — and common in real practice — to shorten it to just city and PIN code, since the recipient likely already knows your full address. Exams generally still expect the fuller version for safety.

2. Date. Same convention as formal letters — written in full.

3. Salutation. "Dear Ravi," "Dearest Amma," "My dear Priya," "Hi Arjun," depending on the closeness and nature of the relationship. A letter to a parent or grandparent in Indian convention often opens with genuine warmth and sometimes a touch of formality out of respect — "Dear Papa" or "Respected Dadi" are both natural, unlike the interchangeable "Dear Mr. X" of business letters.

4. Body. Typically three to four paragraphs, but organised far more loosely than a formal letter:

• An opening paragraph that acknowledges the relationship and often responds to the recipient's last letter or a shared context ("It's been far too long since I last wrote..." or "I hope this letter finds you and everyone at home in good health.").
• A middle section — often two paragraphs — carrying the actual content: news, a story, an invitation, congratulations, comfort, or a request.
• A closing paragraph that looks forward — to the next meeting, the next letter, a wish for the recipient's wellbeing.

5. Complimentary close. This is where informal letters diverge most visibly from formal ones. "Yours affectionately," "With love," "Your loving son," "Yours lovingly," "Warm regards" (for a slightly less intimate but still informal relationship, such as a family friend) are all standard. The close should match the relationship: "Your loving daughter" to a parent, "Yours affectionately" to a close friend, "With love and best wishes" for a congratulatory note to someone slightly less close.

6. Signature. First name only, in almost every case. Signing a letter to your mother with your full name would read as strange, even comic, in a way that is itself worth noting as a common exam-error — candidates trained on formal-letter habits sometimes append a full name out of sheer repetition.

Tone: Warm, Specific, and Genuinely Personal

The single biggest weakness in exam-written informal letters is genericness — vague warmth standing in for real content. "I am fine and hope you are fine too. Everything here is good." tells the reader nothing and reads as though it could be sent to anyone. A strong informal letter names specific people, specific events, specific feelings: not "I had a good time at the festival" but "Amma made her special ariselu for Diwali this year and the whole street could smell it by evening." Specificity is what makes a personal letter feel personal, and it is exactly what separates a top-scoring answer from an adequate one in this genre — perhaps even more so than in the formal genres, where content substitutes for style. Examiners are, in effect, checking whether you can write like a person rather than like a template, and concrete detail is the clearest evidence of that.

Common Errors to Avoid

• Writing an informal letter in a stiff, formal register out of habit — "I am writing to inform you that I recently attended my cousin's wedding" instead of simply "You won't believe how big Priya's wedding turned out to be!"
• Signing off with a full name, or using "Yours faithfully"/"Yours sincerely," which belong to formal correspondence.
• Filling the letter with vague pleasantries instead of actual news, requests, or feelings.
• Forgetting that an informal letter still needs organisation — three or four wandering paragraphs of stream-of-consciousness reads as weaker than a letter with a clear shape, even in this relaxed genre.
• Ignoring the specific occasion given in the question (a congratulation, a condolence, an invitation) in favour of generic "how are you" content — the letter must actually do what the prompt asks.
• Excessive length or repetition — exams typically cap informal letters at 100–150 words, and rambling costs marks for organisation just as it does in formal letters.

Model Letter 1 — To a Friend, Sharing News of a New City and Inviting a Visit

42, Lake View Apartments
Pune, Maharashtra – 411045

16 August 2026

Dear Meera,

I know it's been almost two months since I last wrote, and I'm sorry — between the move and settling into the new job, the days have simply run away from me. But I've finally found a weekend to sit down and tell you everything.

Pune has turned out to be far more fun than I expected. My apartment is tiny, but it's a five-minute walk from a street full of the best vada pav I've ever had, and I've already made friends with two colleagues who insist on dragging me to Sinhagad Fort every other Sunday for the trek. Work itself has been intense — I'm three weeks into the new role and still learning where everything is filed — but my manager is kind and patient, which makes a huge difference when you're new.

Here's the real reason I'm writing, though: Ganesh Chaturthi is coming up next month, and Pune apparently turns into something magical for it. Any chance you could take a few days off and come visit? I have a spare mattress, terrible cooking skills that I promise to make up for with excellent street food recommendations, and I miss you far too much to let another festival pass without seeing you. Let me know — I'll block out the dates the moment you say yes.

Yours affectionately,
Sneha

Model Letter 2 — To a Parent, From a Child Away at College

Hostel Block C, Room 214
IIT Kharagpur, West Bengal – 721302

9 August 2026

Dear Papa,

I hope this letter finds you and Ma in good health, and that Ma's knee has been troubling her less since the last check-up. I meant to call last Sunday but got caught up in a project submission — I'm sorry, and I'll make sure to call this week without fail.

College has been going well. I got my mid-semester results back for Thermodynamics, and I managed an A, which felt like a real relief given how much I struggled with the subject at the start of the term. I've also joined the robotics club here, and we're building a small autonomous rover for a competition in October — it's the first time I've actually enjoyed staying up late for something academic rather than dreading it. Hostel food is still hostel food, though I've discovered a mess worker, Anand-da, who makes an excellent aloo paratha on Sunday mornings, so I can't complain too much.

I wanted to ask — would it be alright if I came home a few days early for Durga Puja this year? The rover competition wraps up on the 8th of October, so I could be home by the 10th instead of waiting until the semester officially ends. I miss home more than I usually let on in these letters, and I'd love the extra days with you both.

Your loving son,
Arnav

Model Letter 3 — To a Sibling, Congratulating Them on a New Job

19, Ashok Nagar
Chennai, Tamil Nadu – 600083

20 August 2026

Dear Kavya,

Ma called me yesterday with the news, and I have been grinning like an idiot ever since — a Product Manager role at a company like that, and only two years out of college! I always knew you'd get there, but I'll admit even I didn't expect it quite this soon.

Do you remember how nervous you were before that first interview round, pacing around the living room rehearsing answers while I kept telling you to just relax and be yourself? Turns out being yourself was more than enough. I'm so proud of how hard you worked for this — the late nights preparing for case studies, the mock interviews you dragged me into on video call at odd hours, all of it clearly paid off.

I want to take you out properly to celebrate the next time I'm in Chennai — you pick the restaurant, and it's entirely on me this time, no arguments. Until then, enjoy every bit of this moment. You've earned it, and I couldn't be happier for you.

With love and pride,
Aditya

Model Letter 4 — Letter of Condolence to a Friend Who Has Lost a Parent

27, Church Street
Kochi, Kerala – 682018

3 August 2026

Dear Rahul,

I heard the news from Vivek this morning, and I've been thinking of you and your family all day. I am so deeply sorry for the loss of your father — I know how close you two were, and I cannot begin to imagine how difficult these past few days must have been for you.

I still remember the summer he taught the two of us to fix a bicycle chain in your garage, patiently going over it three times because neither of us was paying proper attention — he had a way of making even the smallest lesson feel important, and a kind of patience I've rarely seen since. He was a wonderful man, and he clearly poured that same warmth into raising you, because it shows in everything you do.

Please don't feel any pressure to reply to this letter — I only wanted you to know that I am here, in whatever way you need, whether that's someone to talk to or simply someone to sit with in silence. I will call you this weekend, and I will be there for the ceremony if you'll have me. Take care of yourself and your mother in these days, and know that you are both in my thoughts.

With deepest sympathy and love,
Anil

Model Letter 5 — To a Cousin, Describing a Recent Trip

8, Nehru Colony
Dehradun, Uttarakhand – 248001

12 August 2026

Dear Ishaan,

You've been asking me for weeks to tell you about the Valley of Flowers trek, and I've finally got the time to do it justice, so settle in — this is going to be a long letter.

We started from Govindghat at dawn, and I won't lie, the first four kilometres to Ghangaria nearly broke me — my legs were burning by the halfway point, and I seriously considered turning back. But nothing prepared me for what we saw the next morning. The entire valley floor was covered in wildflowers in colours I didn't know existed in nature — blues, deep purples, a kind of orange I can only describe as fire-coloured — stretching all the way to the base of the glaciers. We sat there for almost two hours just taking photographs and, honestly, just staring.

I've attached a few pictures with this letter, though I promise they don't do it justice. You really need to see it yourself — and I mean that literally, because I'm already planning to go back next August, and I want you to come with me this time. Start saving your leave days now; I won't take no for an answer.

Yours affectionately,
Rohan

Model Letter 6 — To a Younger Sibling, Offering Advice Before an Exam

15, Model Town
Ludhiana, Punjab – 141002

7 August 2026

Dear Simran,

Ma told me your board exams start next week, and I've been meaning to write this letter for days — I kept starting it and deleting it because I wasn't sure I had anything useful to say that you haven't already heard a hundred times. But here goes anyway.

I still remember how terrified I was before my own boards, convinced that one bad paper would somehow ruin everything. It didn't, and it won't for you either, whatever happens. What actually helped me back then was something Papa said the night before my first exam — that the marks would fade from memory long before the habit of showing up and doing the work would. You've already put in the hours, Simran; I've seen you at that desk every evening for months, long after I'd have given up. Trust that.

One practical tip, since I know you'll roll your eyes at anything too sentimental: read the full question paper twice before you start writing anything, and attempt the questions you're most confident about first. It sounds obvious, but it's saved me more marks than any last-minute revision ever did. I'll be thinking of you all week, and I've already told Ma to make your favourite kheer the evening your last paper ends. Go show that exam who's boss.

With love,
Divya

Model Letter 7 — To a Friend, Apologising After a Disagreement

33, Salt Lake Sector V
Kolkata, West Bengal – 700091

15 August 2026

Dear Tanvi,

I've rewritten the first line of this letter about six times now, which should tell you how badly I've been wanting to say this properly: I'm sorry. What I said at Ritu's birthday dinner was thoughtless, and I've been replaying it in my head ever since, wishing I could take it back.

You were right that I've been distant these past few months, and instead of admitting that honestly when you brought it up, I got defensive and said something I didn't mean about you always needing attention. That wasn't fair, and it wasn't true — if anything, I've been the one pulling away, buried in work and using it as an excuse not to make time for the people who matter most, and you're at the very top of that list.

I don't expect one letter to undo a bad evening, but I hope you'll let me make it up to you properly — dinner this weekend, my treat, and my full attention this time, phone switched off and everything. I've missed you these past weeks more than my behaviour probably showed, and I'd really like to fix this.

Yours, truly sorry,
Naina

Model Letter 8 — To a Grandparent, Describing Life at a New School

Flat 6B, Palm Residency
Hyderabad, Telangana – 500081

1 August 2026

Dearest Dadi,

I hope this letter reaches you before I next call, because there's so much to tell you that a phone call never seems long enough. I hope your garden is doing well and that the mango tree finally gave you a good harvest this year — you've been telling me about those flowers since March!

My new school has turned out better than I expected. I was so nervous on the first day, remember how I cried on the phone to you the night before? But I've already made two good friends, Meher and Zara, and our English teacher, Mrs. Fernandes, is wonderful — she reads our essays aloud to the class when she likes them, and mine got read out twice last month, which made me think of you, since you're the one who always said I had a way with words even when I was small and writing silly stories about talking animals.

I miss your rajma most of all, Dadi, more than I thought I would. Papa tries his best, but it's just not the same. I'm counting down to Diwali already, when we'll finally be back in Jaipur and I can sit in your kitchen and pester you while you cook, exactly like always.

With all my love,
Ananya

Balancing Emotion With Structure

A letter that reads as genuinely felt is not the same as a letter that reads as unedited. Even a condolence letter or an apology, where emotion runs highest, benefits from the same underlying shape as any other piece of writing: an opening that establishes why you're writing, a middle that says the substantive thing, and a close that points forward — to a visit, a phone call, a next step. Candidates sometimes assume that "informal" gives them licence to abandon structure altogether, producing a letter that circles the same sentiment three or four times without ever quite landing. The strongest informal letters actually show more discipline than they appear to, in the sense that every paragraph is doing distinct work even while the tone stays loose and conversational.

Adjusting Warmth to the Relationship

Not every informal letter carries the same emotional temperature. A letter to a close friend can be playful, teasing, even irreverent. A letter to a parent, in the Indian context especially, usually carries a slightly more respectful undertone even while remaining warm and personal — you might tease a sibling but rarely a parent in quite the same way, and the closing ("Your loving son/daughter") signals that relationship explicitly. A congratulatory letter should center the recipient's achievement rather than your own reaction to it — a common mistake is spending too many lines on how happy you are and too few on what, specifically, the recipient accomplished. A condolence letter requires perhaps the most care of all three: it should acknowledge the loss directly rather than talking around it, offer a specific, genuine memory if one is available rather than a string of generic condolences, and close by making a concrete offer of support rather than a vague one, since vague offers ("let me know if you need anything") are the easiest to make and the least useful to receive.

Email and Messaging-Style Variants

Some exams now ask candidates to write an "informal email" rather than a letter, particularly when testing correspondence between people who would realistically communicate digitally — friends abroad, cousins on different continents, classmates from a program that has since scattered. The format loses the postal address block entirely; you simply open with the salutation after a To: and Subject: line (the subject can be genuinely casual here — "Missing you!" or "Guess what happened this week" are both fine, unlike the precise, referenced subject lines formal correspondence requires). The body keeps the same warmth and specificity discussed throughout this chapter. The sign-off can be shortened further than even a letter's close — "Love," "Take care," "Talk soon," followed by a first name, is entirely natural in this format and mirrors how people actually write to each other digitally.

Where exams specifically test WhatsApp-style or SMS-style informal writing (less common but occasionally appearing in communication-skills papers), the expectation shifts again — brevity, first names or even nicknames, and a conversational fragment style are all acceptable, though this format rarely appears as a standalone question worth significant marks and is more often tested as a comparison exercise ("rewrite this formal complaint as a message to a friend") to check that a candidate understands register shifts rather than as a letter-writing task in its own right.

Reading the Prompt Correctly: Occasion Drives Content

Every informal-letter question in an exam specifies an occasion — a house-warming, a job change, an illness, a quarrel, a trip, an exam. The single most common way marks are lost in this genre is not bad grammar or bad format, but simply failing to write about the occasion the question actually asked for. A candidate given "write a letter to your friend congratulating them on their marriage" who instead produces a pleasant but generic letter about catching up on old times, with congratulations tucked into a single throwaway line, has technically written "a letter" but has not answered the question. Before drafting, underline the occasion in the prompt and make sure at least half the letter's content — usually the entire middle section — is built directly around it. Everything else (the opening warmth, the closing wishes) can be relatively interchangeable across occasions; the middle cannot.

A Bank of Openings and Closings by Relationship

Having a small mental library of natural-sounding openings and closings, sorted by relationship, saves valuable time in an exam and prevents the stiffness that comes from overthinking a first line under pressure.

To a close friend: Openings — "I can't believe it's been this long since we last spoke," "You'll never guess what happened this week," "I've been meaning to write to you for ages." Closings — "Yours affectionately," "Lots of love," "Write back soon, I miss you."

To a parent: Openings — "I hope this letter finds you and Papa in good health," "I've been wanting to tell you about..." Closings — "Your loving son/daughter," "With love and respect," "Touching your feet from afar" (a traditional, warm Indian convention still very much in use in letters to elders).

To a sibling: Openings — "Ma told me the news and I had to write immediately," "It's your turn to hear from me for once." Closings — "With love," "Your proud brother/sister," "See you soon, I hope."

To a grandparent: Openings — "Dearest Dadi/Nani, I hope your health has been good," "I think of you every time..." Closings — "With all my love and respect," "Your loving grandchild."

For condolence: Openings — "I was deeply saddened to hear...," "Words feel inadequate, but I wanted to write to you regardless." Closings — "With deepest sympathy," "Thinking of you always," "In shared sorrow."

Use this bank as a starting point, never as a substitute for the specific detail that makes a letter feel genuine — a strong opening line still needs to be followed by real content, not simply repeated affection in different words across three paragraphs.

Practice Prompts

• Write a letter to a friend who has just moved abroad, sharing news from home and asking about their new life.
• Write a letter to your grandmother, describing how you celebrated a recent festival without her.
• Write a letter to a friend congratulating them on clearing a competitive exam after several attempts.
• Write a letter to a cousin who has been unwell, offering comfort and sharing something to look forward to once they recover.

In each case, before writing, identify one specific detail — a person's name, a place, a memory, a small concrete fact — that only you would know to include. That detail, more than any phrase of affection, is what will make the letter read as genuinely personal rather than generically warm.

Why Examiners Take This Genre Seriously

It would be easy to treat the informal letter as the "soft" question on a paper, the one you dash off after spending real effort on the official and business letters. That instinct undersells what this section actually measures. Precision under freedom is a harder skill than precision under constraint — anyone can follow a rigid format correctly once they've memorised it, but writing something that is simultaneously loose, warm, well-organised, and specific requires genuine control of the language rather than recall of a template. Employers, examiners, and — eventually, if you clear the exam — your own working life will all ask you to write informally at some point: a message to a colleague, a note to a client you know well, an email to a mentor. The habits built in this chapter — specificity over vague warmth, structure without stiffness, tone matched to relationship — transfer directly to that everyday writing, which is exactly why the genre earns its place in a serious composition syllabus rather than being treated as a throwaway question.

A Final Worked Example: A Letter That Combines Several Purposes

Real letters rarely serve exactly one purpose, and exam prompts occasionally reflect this by asking for a letter that shares news, offers thanks, and extends an invitation all at once. Here is how that combination looks in practice, in a letter to an aunt after a family visit.

56, Koregaon Park
Pune, Maharashtra – 411001

17 August 2026

Dear Chitra Mausi,

I got home safely on Sunday evening, though the train was delayed by nearly two hours, which gave me far too much time to sit and think about how much I already miss everyone at your place.

Thank you, truly, for hosting us for the whole week — I know Mausa had to rearrange half his work schedule to take us around the city, and your kitchen barely had a day off between all the meals you cooked. Rohit still hasn't stopped talking about the boat ride at the lake, and I have to admit your gulab jamun has ruined every other version I've had since. It meant a great deal to all of us, especially after the year we'd had, to simply sit around your table and laugh again.

I wanted to let you know that Papa's transfer has finally come through, and we'll be moving to Pune ourselves in October — which means, happily, that you'll be stuck with us as regular visitors rather than once-a-year guests from now on! I hope that's not too alarming a thought. We'd love to have you and Mausa over for a proper meal once we're settled, as a small way of returning even a fraction of your hospitality.

With love and gratitude,
Neha

Notice how this letter still moves through a clear shape — safe arrival, thanks with specific detail, news, invitation — even while covering three distinct purposes in roughly 150 words. That discipline, more than any particular phrase, is the transferable skill this chapter has been building toward.

Quick Revision Checklist

• Address, date, warm salutation matched to the relationship, three to four loosely organised paragraphs, closing matched to the relationship, first-name signature only.
• Never use "Yours faithfully" or "Yours sincerely" — reserve those for formal letters.
• Include specific names, places, and details — genericness is the single biggest mark-loser in this genre.
• Make sure the letter actually addresses the occasion given in the prompt (congratulation, condolence, invitation, news) rather than drifting into generic pleasantries.
• Keep organisation even while keeping tone relaxed — a shape still matters, even in an informal letter.
• Read the prompt's stated occasion carefully and build the letter's middle section directly around it, rather than defaulting to generic catching-up content.

A final practical note: try rewriting one of the model letters above in your own voice, keeping the same occasion and relationship but changing every specific detail to something drawn from your own life. This single exercise, repeated across a few different relationships and occasions, does more to build genuine fluency in this genre than reading twice as many finished examples without ever attempting your own.
