[EX Q]: 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.
[EX A]: You are probably looking for the word ephemeral. ephemeral: Lasting for a very short time.

[EX Q]: Is there a name for these kind of doubled words? For example: hanky-panky flim-flam hoity-toity boo-hoo zig-zag Note that some rhyme and others do not.
[EX A]: hanky-panky is an example of rhyming reduplication zig-zag is an example of ablaut reduplication.

[EX Q]: Are there programmers here? I'd like to know how you guys pronounce cURL. Because I don't live in a country that uses English, I haven't heard it yet.
[EX A]:
According to the authors of the library, We pronounce curl and cURL with an initial k sound: [kurl]. This same FAQ notes that one of the reasons for which the name was chosen was '[t]he fact it can also be pronounced 'see URL'', an obvious pun on the use of the library, which as you know is to retrieve web resources. For what it's worth, I always pronounce it with the initial k sound, as in the English word 'curl.'
