01 What is Letter Writing?

Letter writing is the art of communicating a message in a structured, written format addressed to a specific person or organization. It is one of the oldest and most important forms of communication — used in education, business, government, and personal life.

For students, letter writing is an essential skill tested in school exams (Class 6–12, CBSE, ICSE, and competitive exams) and required in real-life situations — applying for leave, writing to a principal, complaining to an authority, or staying in touch with family and friends.

Why learn letter writing? A well-written letter demonstrates clarity of thought, proper language use, and professionalism — skills that serve students throughout their academic and professional life. Examiners award high marks to letters that follow the correct format, have a clear purpose, and use appropriate language.

Sample Informal Letter — Letter to a Friend About New School
45, Rose Garden Colony, Jaipur – 302001 26th April, 2026 Dear Arjun, How are you? I hope you and your family are doing well. I have been meaning to write to you since we moved cities last month — it finally feels real now! I have joined St. Mary's School here in Jaipur, and honestly, it took me a few weeks to settle in. The classrooms are huge and the library is amazing — I could spend hours there! I have made a couple of friends, Sneha and Tanvi, who have been very helpful in showing me around. However, I really miss our old school and our gang. Do you remember how we used to sit under the big banyan tree during lunch? I wish I could teleport back sometimes! Please write back soon and tell me all the news. How are your football practice sessions going? I miss cheering for you! With warm regards, Rohan P.S. Sneha says Jaipur's kachoris are the best — she might be right!

05 Expert Tips & Common Mistakes
Use the correct salutation
Formal: "Respected Sir/Madam," — Informal: "Dear [Name]," — Never mix the two styles in the same letter.
Write a clear subject line
In formal letters, the subject must be specific. Avoid vague lines like "Regarding the matter." Be precise.
Use 3 paragraphs in the body
Always structure: (1) Introduction & purpose, (2) Details & explanation, (3) Polite request or closing remark.
Match tone to letter type
Formal = polished and respectful. Informal = warm and natural. Slang and contractions are inappropriate in formal letters.
Avoid these common mistakes
Starting the first sentence with "I". Forgetting date or address. No subject line in formal letters. Using incorrect closing phrases.
Word limit in exams
Most boards expect 120–150 words. Stay within the limit — examiners penalize for excessive length. Quality over quantity.
