A valediction is a phrase used to say goodbye at the end of a letter.[1][2][3] It also refers to the act of saying goodbye to someone. It comes from the Latin vale dicere, which means "to say farewell".[4] Valedictions are normally written before the signature in a written message. The words used usually express respect or regard for the person to whom the message is written.
English valedictions often contain the possessive pronoun "yours"; for example, Yours truly. In the United Kingdom, Yours sincerely or Yours faithfully are most common.
