Lesson Content/Board Summary
Writing
Informal Letter Format and Features
An informal letter is a personal letter written to friends, family members, or close acquaintances. It is usually written in a friendly and casual tone, without strict adherence to formal rules of language, although good grammar and clear expression are still important.
Format of an Informal Letter
An informal letter typically follows a simple structure:
- Sender’s Address and Date: This is written at the top right-hand corner of the page. It includes the writer’s address and the date the letter is written.
- Salutation/Greeting: This is the opening greeting, written on the left-hand side, below the address and date. It is usually personal and friendly, e.g., “Dear [Name of friend/family member],” or “My Dearest [Name],”
- Body of the Letter: This is the main content of the letter, divided into paragraphs. It contains the message the writer wishes to convey. The tone is conversational and friendly.
- Closing/Subscription: This is the polite ending of the letter, written on the right-hand side, below the body. Examples include “Yours affectionately,” “Your friend,” “Best regards,” “Love,” etc.
- Signature: The writer’s first name or nickname follows the closing.
Example of Informal Letter Format
[Sender's Address] No. 5, Adeola Street, Garki, Abuja. 15th October, 2024. Dear Tunde, How are you doing? I hope this letter finds you well. I was so happy to receive your last letter... ... ... I look forward to hearing from you soon. Yours affectionately, Chiamaka
Features of an Informal Letter
Informal letters have distinct features that differentiate them from formal letters:
- Tone: The tone is personal, friendly, and conversational. It reflects the close relationship between the writer and the recipient.
- Language: The language used is usually simple, direct, and casual. Contractions (e.g., “I’m,” “don’t”), slang, and colloquialisms may be used, depending on the closeness of the relationship.
- Organisation: While there is a standard format, the organisation of ideas within the body can be more flexible. Paragraphs flow naturally from one idea to another.
- Purpose: Informal letters are written for various personal reasons such as sharing news, asking about well-being, inviting someone, thanking someone, or simply maintaining contact.
- Personal Details: They often contain personal anecdotes, feelings, and opinions.
- No Recipient’s Address: Unlike formal letters, the recipient’s address is not usually included on the letter itself, only on the envelope.
