Usage notes
• In British English the adverb almost invariably follows the word yours at the end of a letter; in most dialects of American English it usually precedes it. As a general rule, sincerely is only employed if the name of the recipient is already known to the writer; a letter begun with Dear Sir or Dear Madam finishes with faithfully. Yours on its own and yours ever are less formal than the other forms.
