what is the format of an infomal letter?

Dear Student,

Here is a sample format for an informal letter:

Rules for Writing Formal Letters:

There is a set pattern for writing a formal or a business letter. Furthermore, you try to write as simply and as clearly as possible, and not to make the letter longer than necessary. One should never use informal language.

Addresses:

1) Your Address
The return address should be written in the top right-hand corner of the letter.

2) The Address of the person you are writing to.
The inside address should be written on the left, starting below your address.

Date:

Put the date on the upper left side of the page. Write the month as a word.

Salutation or greeting:

1) Dear Sir or Madam,
2) If you know the name, use the title (Mr, Mrs, Miss or Ms, Dr, etc.) and the surname only. 3) If you are writing to a woman and do not know if she uses Mrs or Miss, you can use Ms, which is for married and single women.

Content of a Formal Letter

First paragraph
The first paragraph are the opening lines which should be short and state the purpose of the letter- to request, apologise for something, etc.

Second Paragraph

The paragraph or paragraphs in the middle of the letter is the body of the letter which should contain the vital information explaining the purpose behind writing the letter. Letters shouldn’t be too lengthy. Thus, the information should be kept precise, concentrating on organising it in a clear and logical manner rather than expanding too much.

Last Paragraph
The last paragraph of a formal letter should affirm what action you expect the recipient to take- to refund, send you information, permit a request, etc.
