Pronoun

1. That which belongs to you; the possessive second person pronoun used without a following noun.

   If this edit is mine, the other must be yours.

   Their encyclopedia is good, but yours is even better.

   It’s all yours.

2. Yours sincerely, Yours faithfully, Yours, Sincerely yours

Usage notes

• In British English the adverb almost invariably follows the word yours at the end of a letter; in 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.
