Lesson Content/Board Summary
Writing Informal And Formal Letters
Types of Letters
There are two main types of letters:
- Informal Letters: Also known as friendly letters, personal letters, or social letters.
- Formal Letters: Also known as official letters, business letters, or professional letters.
Informal Letters
Purpose and Intended Recipient
Informal letters are written to friends, family members, or close acquaintances. Their purpose is usually personal communication, such as sharing news, expressing feelings, inviting someone, or thanking someone.
Layout of an Informal Letter
- Writer’s Address and Date: Usually placed at the top right corner of the page.
- Salutation: A friendly greeting to the recipient (e.g., Dear [Name], My Dearest [Name], Hi [Name]).
- Body: The main message, organised into clear paragraphs. The language is conversational and personal.
- Complimentary Close: A friendly closing phrase (e.g., Yours sincerely, Yours affectionately, Best regards, Love, Cheers).
- Signature: The writer’s first name or a familiar nickname.
Tone and Language
The tone of an informal letter is casual, personal, and friendly. Contractions (e.g., I’m, don’t, you’ve) and slang can be used. The language is relaxed and reflects the close relationship between the writer and the recipient.
Formal Letters
Purpose and Intended Recipient
Formal letters are written to people in official capacities, institutions, or businesses. Their purpose is usually official communication, such as job applications, complaints, requests, inquiries, or official invitations.
Layout of a Formal Letter
- Writer’s Address: Placed at the top right corner of the page.
- Date: Written directly below the writer’s address.
- Recipient’s Address: Placed on the left side of the page, below the date.
- Salutation: A formal greeting (e.g., Dear Sir/Madam, Dear Mr./Mrs./Ms. [Surname], To Whom It May Concern).
- Title/Subject: A clear, concise heading that states the main purpose of the letter (e.g., APPLICATION FOR ADMISSION, COMPLAINT ABOUT PRODUCT).
- Body: The main message, organised into clear, concise paragraphs. Information is presented formally, directly, and objectively.
- Complimentary Close: A formal closing phrase (e.g., Yours faithfully, Yours sincerely, Respectfully yours).
- Signature: The writer’s full name, often followed by their designation or title.
Tone and Language
The tone of a formal letter is formal, respectful, and objective. It avoids contractions, slang, and overly emotional language. The vocabulary should be precise, polite, and professional.
