Answer: Judge or God, clemency or mercy.. Supplication, a noun, can logically be applied to any situation in which you plead to someone in power for help or a favor. Supplication: comes from the Latin verb supplicare, which means "to plead humbly." (etymonline.com) Supplication (also known as petitioning) is a form of prayer, wherein one party humbly or earnestly asks another party to provide something, either for the party who is doing the supplicating (e.g., "Please spare my life.") or on behalf of someone else (e.g., "Please spare my child's life.").

[A]: yes


[Q]: Question: This is a question for English wordsmiths. Is there a word that "feels" like the word "ethereal" that means something ethereal that quickly disappears. Or is "ethereal" the correct word choice for this? Ethereal was the first word that popped into my head for this. From the various definitions that I've looked at for ethereal, it says delicate, beautiful, heavenly, etc. but not necessarily quickly vanishing, except for the secondary definitions related to ether that suggests it evaporates. I'm just wondering if there is a better word than this. I'm using the term "ethereal skill" to describe a certain type of pilot skill (instrument flying) that requires tremendous practice to achieve proficiency, and once proficiency is achieved it is a beautiful thing, but if you don't practice it regularly, that skill vanishes after a few weeks. USAGE: Instrument proficiency is an ethereal skill that once obtained must be maintained through constant and regular practice. 
Answer: You are probably looking for the word ephemeral. ephemeral: Lasting for a very short time.
[A]: yes


[Q]: Question: In French, if I want to quantify a very small amount of time (but not fixed: it can be 5 ms or 0.1 ms) I can use a pouieme. Is there an equivalent in English? I'm not looking for an expression but for a standalone word. EDIT : In fact, I need to create a c++ class which will measure time and be equal to a 1/600s. In French, pouieme is a cute word which can means a very small but undefined amount of time. The issue is that I must write english code and that's why I would like to find a standalone equivalent. 
Answer: A 90's slang pop-culture reference would be 'mmmbop' from 1997's one hit wonder band 'Hanson' from the song with the same title.
[A]:
no
