Form of address

Extracted from the Wikipedia article Style (form of address).
A style of office, also called manner of reference, or form of address when someone is spoken to directly, is an official or legally recognized form of reference for a person or other entity (such as a government or company), and may often be used in conjunction with a personal title. A style, by tradition or law, precedes a reference to a person who holds a post or political office and is sometimes used to refer to the office itself. An honorific can also be awarded to an individual in a personal capacity. Such styles are particularly associated with monarchies, where they may be used by a wife of an office holder or of a prince of the blood, for the duration of their marriage. They are also almost universally used for presidents in republics and in many countries for members of legislative bodies, higher-ranking judges, and senior constitutional office holders. Religious leaders also have styles.
