Address terms are linguistic expressions used by a speaker to start conversation or call someone. George Yule defines address form as a word or phrase that is used for a person to whom speaker wants to talk. Address forms or address terms are socially oriented and expose the social relationship of interlocutors. Maloth explains "When we address a person we should use suitable term depending on the appropriate situation where we are in". Moreover social situations determine the use of a suitable address form for a person. 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, 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. Leading religious figures also have styles.
