text: Second lady and second gentleman are honorary titles often used in reference to the spouse of a vice president, or spouse of a lieutenant governor or other second-ranked government official. The title is styled after first lady or first gentleman, which are used to describe the spouse of a president or governor. In discussing both spouses, they may be referred to as the second couple, and if they have children, they are known collectively as the second family.
  The expression "second lady in the land" has also been used to refer to the second-highest ranking female in a monarchy, such as a crown princess if there is a queen.
