Context paragraphs:
Seungjeongwon: Seungjeongwon was the Royal Secretariat during the Joseon Dynasty of Korea (1392 - 1910) in charge of receiving and delivering the king's order.  The office was also called "Jeongwon", "Huwon", "Eundae", or "Daeeonsa".  According to the "Gyeongguk daejeon" (Complete Codes of Law), the Seungjeongwon had 6 Royal Secretaries ("Seungji" 承旨), whose ranks were in the 3rd senior grade, as well as two recorders ("juseo" 注書).  The duties of the royal secretaries were primarily to deliver the monarch’s orders to government organizations (under the Joseon administrative system the monarch never delivered his orders directly to any government office) and to report on official affairs of the state organizations to the throne.  The six secretary system is explained by the fact that the government of Joseon was composed of six Boards (or Ministries).  The six secretaries served respectively the Boards of Personnel, War, Taxation, Rites, Works, and Punishment.  However, the secretaries were not limited to liaison work between the Six Boards and the monarch; they also reported to the king the business of all government offices, primary among these being the State Council ("Uijeong-bu"), the Office of Censor-General ("Saganwon"), and the Office of Inspector-General ("Saheon-bu").  As the name implies, the primary duty of the recorders was to make a record of all the official business handled by the secretaries.  As the work of the secretaries had to be conducted at all hours, and it was required that they have ready access to the monarch at all times, the office the Seungjeongwon was established within easy reach of the king at court.

Commander-in-chief of the British Armed Forces: The Commander-in-Chief of the British Armed Forces is a position vested in the British monarch, currently Queen Elizabeth II, who as Sovereign and head of state is the "Head of the Armed Forces".  Long-standing constitutional convention, however, has vested "de facto" executive authority, by the exercise of Royal Prerogative powers, in the Prime Minister and the Secretary of State for Defence, and the Prime Minister (acting with the support of the Cabinet) makes the key decisions on the "use" of the armed forces.  The Queen, however, remains the "ultimate authority" of the military, with officers and personnel swearing allegiance only to the monarch.

Royal Secretary: Royal Secretary (Basilikos Grammateus, Secretarius Regius) is a position at the court of a monarch generally responsible for communicating the sovereign's wishes to the other members of government.

In some cases the office of Royal Secretary evolved into the Secretary of State.

Canadian Secretary to the Queen: The Canadian Secretary to the Queen (French: "Secrétaire canadien de la Reine" ) is the senior operational member of the Royal Household of Elizabeth II, Queen of Canada.  It is the principal channel of communication between the monarch and her Canadian government, provincial governments, and the governments of the 15 other Commonwealth realms, as well as managing the monarch's other correspondence in the Canadian context and drafting speeches the Queen delivera in Canada or on Canadian topics.  The secretary is responsible for advising the prime minister "on matters related to the Canadian Crown, including providing advice on the Government of Canada's heritage-related commemorative initiatives, high level coordination of Royal Tours to Canada, and state ceremonial and protocol advisory functions."

Valet de chambre: Valet de chambre (] ), or "varlet de chambre", was a court appointment introduced in the late Middle Ages, common from the 14th century onwards.  Royal households had many persons appointed at any time.  While some valets simply waited on the patron, or looked after his clothes and other personal needs, itself potentially a powerful and lucrative position, others had more specialized functions.  At the most prestigious level it could be akin to a monarch or ruler's personal secretary, as was the case of Anne de Montmorency at the court of Francis I of France.  For noblemen pursuing a career as courtiers, like Étienne de Vesc, it was a common early step on the ladder to higher offices.
