A well-written letter communicates ideas clearly and professionally. Letters can be formal (business, official) or informal (personal, friendly). Each type has specific conventions and tone.
Letter Writing — The Rules
- Formal letter parts: sender's address, date, recipient's address, salutation, body, closing, signature
- Informal letter parts: less structured; may skip addresses; uses casual language and friendly tone
- Salutation: "Dear Sir/Madam" (formal), "Dear Mr./Ms./Dr. [Name]" (formal), "Dear [Name]" (semi-formal), "Hi/Hello [Name]" (informal)
- Closing: "Yours sincerely" (formal), "Best regards" (professional), "Yours truly" (formal), "Cheers" (informal)
- Tone: formal letters are respectful and clear; informal letters are personal and conversational
Examples
- Formal opening: "I am writing to inquire about..." or "I am pleased to inform you that..."
- Informal opening: "I hope you are doing well!" or "How have you been?"
- Formal body: "Please note that the deadline for submission is December 31st."
- Informal body: "We had such a great time at the party, and I wanted to thank you for organizing it!"
- Formal closing: "I look forward to hearing from you." (+ "Yours sincerely")
- Informal closing: "Hope to see you soon!" (+ "Cheers")
Common Mistakes
These are the errors that cost marks most often. Each line gives the mistake and the correction.
- Wrong tone: mixing formal and informal ("I am writing to say what's up" — maintain consistent tone)
- Missing address details: formal letters need sender and recipient addresses
- Vague purpose: start with a clear statement of why you are writing
Practice Questions
Attempt each one before reading the answer beneath it — checking first teaches nothing.
Write a formal opening line for a complaint letter to a manager.
Example: "I am writing to formally lodge a complaint regarding the service I received on December 5th."
Is this closing appropriate for a business letter? "See ya later!"
No, too informal. Use: "Yours sincerely", "Best regards", or "Yours truly".
What is the difference between "Dear Sir" and "Dear Sir or Madam"?
"Dear Sir or Madam" is more inclusive when you don't know the recipient's gender. Use specific names when available.
Frequently Asked Questions
Should I use a colon or comma after the salutation?
Formal letters: colon "Dear Mr. Smith:". Informal/friendly letters: comma "Dear John," or no punctuation.
How many paragraphs should a formal letter have?
Typically 3-4: introduction (state purpose), middle paragraphs (provide details/explanation), conclusion (clear action or closing).
What should I include in a thank-you letter?
Specific mention of what you are thanking them for, how it helped, and a warm closing. Keep it brief and genuine.
