Majesty

Majesty (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 was formerly inferior to the style of Imperial Majesty. It has cognates in many other languages, especially Indo-European languages of Europe.
