Hi,

I just started a page in the Klingon.wiki listing metaphorically used
words and also metonyms. Okrand did not name them as such, and I noticed
ther are others that fit in such alist which were not explicitally label
as such, like {Soj} meaning "matter, affair" instead of "food".

Then I noticed that many of the idioms use (or are) metaphors, so it
kind of overlaps. Now come the questions...

1. Did anyone ever make such a compilation already?

Not exactly, but if you look at {boQwI'}'s database, sentences which are idioms are tagged as such (they have "part_of_speech" set to "sen:idiom"). Not all of them are metaphors.

The list isn't that long, so I'll post it here:

2. Would you understand and/or accept words taken from idioms in a
different context, like if I use {Ha'quj} without the verb {nge'} -
would you know I talk about somebody's pride? (Well, KGT says that
phrases outside of context would only be understood literally, but I'd
ask anyway.)

No, if I thought it wasn't literal, I would think you were talking about their {tuq}, which is what it's a symbol of.
 
3. Some idioms consist of only a noun phrase, like {naH jajmey}.
Wouldn't that also be a metonymy?
 
Some idioms are instances of metonymy, but not all idioms which are noun phrases are metonyms. {chatlh} meaning "nonsense" is an idiom, but not a metonym.
