The Vietnamese word "ngự sử" refers to a "royal adviser" or "imperial inspector" in the context of historical Vietnam. This position was significant in the royal court, where the ngự sử had the important role of advising the emperor and ensuring that the ruler did not make unjust or harmful decisions. The ngự sử was also responsible for overseeing the actions of other officials and maintaining moral standards within the government.
In more advanced discussions, you might explore the evolution of the role of ngự sử through different dynasties, such as the Lý, Trần, and Nguyễn dynasties, analyzing how the responsibilities and powers of ngự sử changed over time.
In modern Vietnamese, "ngự sử" is less commonly used outside of historical contexts, so its meaning is primarily tied to discussions about Vietnam's past governance. It does not have a direct equivalent in contemporary roles today.
