Matthew Said:

When do you sign a letter "Yours sincerely"?

We Answered:

American usage: "Sincerely yours" is used for personal letters that are somewhat formal. Very informal personal letters may be signed "Fondly" or "With love" or something similar.

Business letters are usually signed "Yours truly". An acceptable variation is "Very truly yours", although that is not used very often. I have never seen an American business letter signed "Yours faithfully" or any variation of that.

rule of thumb:

if you start a letter with

you end with
Yours faithfully


if you start a letter with
(person's name)
you end with
Yours sincerely
or
regards
or
something like that (depending on how well you know them)

Margaret Said:

When writing a formal letter, when should you use "Yours Sincerely", "Yours Truly" and "Yours Faithfully"?

We Answered:

For a formal letter, I would drop the 'yours'and just put "sincerely" Truly and faithully are words reserved more for a friendly letter.

Kathy Said:

How do I end this letters? Yours sincerely?

We Answered:

If you don't know the person, the letter should begin "Dear Sir" and end "Yours faithfully". "Yours sincerely" should only be used if you address the person by name.

Bernice Said:

Should we write "Yours Sincerely" , "With kind Regards" in left hand bottom of the letter or in the right hand?

We Answered:

As far as I'm aware you always write it in the left hand bottom of a letter whether its formal or informal. This is what I've always been told anyway.

Mary Said:

Sure. Since it's for an assignment you should put "yours sincerely" even though it's to a friend.
You're on thee right track! :)
