qunnoq :
Is there a noun {waH} meaning "the test of one's abilities" ?
No AFAIK, but there is the noun {qaD} "challenge, test (of one's abilities) (KCD/KGT).
I noticed this entry in my dictionary, and I think that it must be a mistake on my part.
You may have conflated the noun {laH} "ability" with the verb {waH} "taste, try out (e.g. food), test, use experimentally", introduced on msn.onstage.startrek.expert.okrand (7/01/1997): {waH} means "try out, use (experimentally)" and it is also the word used for taste in the sense of trying out food to see if it's prepared properly or to find out if you like it. qagh vIwaH I taste the gagh. ("I try out the gagh [to see how it tastes]") SEE ALSO: chov assess, evaluate, test (v) tob test conclusively, prove (v) Daj test inconclusively (v) -- Voragh tlhIngan ghantoH pIn'a' Ca'Non Master of the Klingons
