Highness, often used with a personal possessive pronoun (His/Her/Your Highness, the first two abbreviated HH) is an attribute referring to the rank of the dynasty (such as Royal Highness, Imperial Highness) in an address. It is literally the quality of being lofty or high, a term and style used, as are so many abstractions, as a style of dignity and honor, to signify exalted rank or station.
