Could you please Help me When do I write a Formal and an Informal Letter?
And please give me the structure of the letter

Hello hybmu, and welcome to the forums.

Generally speaking, you write a formal letter in formal situations. You would use a formal letter to a business, the government, or to a person you didn't know.

You use an informal letter informal situations: to a friend, primarily.

There are a lot of good Internet resources on how to format letters. Have you tried using Google and searching for formal letter format?
