quân vô hí ngôn

Vietnamese edit

Sino-Vietnamese word from 君 (“monarch”), 無 (“not”) and 戲言 (“to joke, to jest, to say something playfully and not in earnest”).

Based on a quote in Lüshi Chunqiu (translation adapted from Knoblock & Riegel 2001):

天子無戲言。天子言，則史書之，工誦之，士稱之。 [Vietnamese Literary Sinitic, trad.]
From: Lü Buwei, Master Lü's Spring and Autumn Annals, 239 BCE
Thiên tử vô hí ngôn. Thiên tử ngôn, tắc sử thư chi, công tụng chi, sĩ xưng chi. [Sino-Vietnamese]
The Son of Heaven utters no playful words. What the Son of Heaven says, the scribes record, the musicians chant, and the knights proclaim.

A monarch should not say anything in jest
(by extension) A person in power should not say anything in jest and not in earnest
