MajestyMajesty (abbreviated HM for Her Majesty or His Majesty, oral address Your Majesty; from the Latin maiestas, meaning "greatness") is used as a manner of address by many monarchs, usually kings or queens. Where used, the style outranks the style of (Imperial/Royal) Highness, but is inferior to the style of Imperial Majesty. It has cognates in many other languages, especially of Europe.
ExcellencyExcellency is an honorific style given to certain high-level officers of a sovereign state, officials of an international organization, or members of an aristocracy. Once entitled to the title "Excellency", the holder usually retains the right to that courtesy throughout their lifetime, although in some cases the title is attached to a particular office and is held only during tenure of that office.
Style (form of address)A style of office or form of address, also called manner of address, is an official or legally recognized form of address 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.
HonorificA honorific is a title that conveys esteem, courtesy, or respect for position or rank when used in addressing or referring to a person. Sometimes, the term "honorific" is used in a more specific sense to refer to an honorary academic title. It is also often conflated with systems of honorific speech in linguistics, which are grammatical or morphological ways of encoding the relative social status of speakers. Honorifics can be used as prefixes or suffixes depending on the appropriate occasion and presentation in accordance with style and customs.
