English, South African English as examples) without full stops (periods) but in American English and Canadian English always end with a period. Other honorifics may denote the honored person's occupation, for instance "Doctor", "Esquire", "Captain", "Coach", "Officer", "The Reverend" (for all Christian clergy) or "Father" (for a Catholic, Eastern Orthodox, Oriental Orthodox, or Anglican Christian priest), "Rabbi" for Jewish clergy, or Professor. Holders of an academic doctorate, such as a PhD, are addressed as "Doctor" (abbreviated Dr). Some honorifics act as complete replacements for a name, as "Sir" or "Ma'am", or "Your Honour/Honor". Subordinates will often use honorifics as punctuation before asking a superior a question or after responding to an order: "Yes, sir" or even "Sir, yes, sir." Judges are often addressed as "Your Honour/Honor" when on the bench, the plural form is "Your Honours" and the style is "His/Her Honour". If the judge has a higher title, that may be the correct honorific to use, for example, for High Court Judges in England: "Your Lordship" or "My Lord". Members of the U.S. Supreme Court are addressed as "Justice". Similarly, a monarch ranking as a king/queen or emperor and his/her consort may be addressed or referred to as "Your/His/Her Majesty", "Their Majesties", etc. (but there is no customary honorific accorded to a female monarch's consort, as he is usually granted a specific style). Monarchs below kingly rank are addressed as "Your/His/Her Highness", the exact rank being indicated by an appropriate modifier, e.g. "His Serene Highness" for a member of a princely dynasty, or "Her Grand Ducal Highness" for a member of a family that reigns over a grand duchy. Verbs with these honorifics as subject are conjugated in the third person (e.g. "you are going" vs. "Your Honour is going" or "Her Royal Highness is going".) Protocol for monarchs and aristocrats can be very complex, with no general rule; great offence can be given by using a form that is not exactly correct. There are differences between "Your Highness" and "Your Royal Highness"; between "Princess Margaret" and "The Princess Margaret". All these are correct, but apply to people of subtly different rank. An example of a non-obvious style is "Her Majesty Queen Elizabeth The Queen Mother", which was an official style, but unique to one person. In music, a distinguished conductor or virtuoso instrumentalist may be known as "Maestro". In aviation, pilots in command of a larger civil aircraft
