Royal Highness

Royal Highness is a style used to address or refer to some members of royal families, usually princes or princesses. Monarchs and their consorts are usually styled Majesty.

When used as a direct form of address, spoken or written, it takes the form Your Royal Highness. When used as a third-person reference, it is gender-specific (His Royal Highness or Her Royal Highness, both abbreviated HRH) and, in plural, Their Royal Highnesses (TRH).
