Study in quietude (5)
I believe the answer is:
etude
This clue could be a double definition.
'study' is the first definition.
(I've seen this before)
'quietude' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'in' is the link.
Can you help me to learn more?
(Other definitions for etude that I've seen before include "Testing musical composition" , "Indian statesman" , "Short composition for a solo instrument" , "(Musical) study" , "Noted composition" .)
