Study French (5)
I believe the answer is:
etude
This clue could be a double definition.
'study' is the first definition.
(I've seen this before)
'french' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for etude that I've seen before include "Noted composition" , "bit of practice" , "short musical piece" , "Short piece of music for solo instrument" , "(Musical) study" .)
