Letter & Email Writing —
Three Registers, Three Relationships

Formal, informal, official — three different registers for three different relationships. Knowing which to use, and when to shift, is a professional skill that begins in Class 6 and lasts a lifetime.

The Three Registers

A register is the level of formality appropriate for a particular relationship and purpose. Using the wrong register is like wearing formal clothes to a friend's birthday — technically fine, but socially wrong.

Informal
Letter to a Friend or Family Member
Conversational tone · Personal · Contractions acceptable (I've, It's) · Starts "Dear [Name]," · Ends "Yours lovingly / Your friend,"
Semi-Formal
Letter to Teacher or Known Official
Respectful but not stiff · Clear purpose · No contractions · Starts "Dear Sir/Madam," · Ends "Yours sincerely,"
Formal / Official
Letter to Authority or Editor
Strictly formal · Impersonal · No contractions · Starts "Sir/Madam," · Ends "Yours faithfully," · Subject line required
💡 Most Common Exam Letter Types

CBSE and SSC ask for:
• Letter to the Editor (formal — complaint or suggestion)
• Letter to the Principal (formal — request or leave)
• Letter to a friend (informal — sharing news or invitation)
• Job application / leave application (formal)

🇮🇳 Indian English — The Critical Rule

Indian English follows British conventions:
"Yours faithfully" — when you do NOT know the name (Dear Sir/Madam)
"Yours sincerely" — when you DO know the name (Dear Mr Sharma)
Never mix them. Never use "Yours truly" in Indian formal letters.

Common Letter Writing Errors
❌ Wrong Closing Salutation
⚠️ Spot the Error
Letter begins "Dear Sir," → ends "Yours sincerely,"
✓ "Dear Sir/Madam" (name unknown) → "Yours faithfully"
✓ "Dear Mr Sharma" (name known) → "Yours sincerely" → Indian English (British standard): "Yours faithfully" when name is unknown; "Yours sincerely" when name is known. Never mix them. This error costs marks in every exam.
❌ Missing Subject Line in Formal Letters
⚠️ Spot the Error
A formal letter to the Principal or Editor with no subject line at all.
✓ All formal letters require a subject line: "Subject: Request for Medical Leave" — bold, one clear line, placed after the salutation or before it depending on the format taught by your board. → Missing the subject line typically costs 1 mark in CBSE exams. It tells the reader what the letter is about before they begin reading.
❌ Informal Language in a Formal Letter
⚠️ Spot the Error
"Hi Sir, I want to take leave. It's because I'm sick. Thanks, Ananya"
✓ "Respected Sir, I am writing to request leave of absence... I shall be grateful for your consideration. Yours faithfully, Ananya Desai" → Contractions (I'm, It's, I've), casual greetings (Hi), and informal closings (Thanks) are for personal letters only. Formal letters use full forms and respectful language throughout.
💡 Address Placement

Formal letters: Sender's address top-left
Informal letters: Sender's address top-right
Recipient's address: Only in formal letters — not in informal letters to friends
Date always follows the sender's address.

⚠️ "Esteemed" Overuse

Indian school writing overuses "esteemed": esteemed newspaper, esteemed school, esteemed sir. Use it exactly once — in the traditional opening of a Letter to the Editor. Everywhere else, drop it entirely. It sounds hollow when repeated.
