Language used by Chopin buff (6)
I believe the answer is:
polish
This clue could be a double definition.
'language' is the first definition.
(Polish is a language)
'chopin buff' is the second definition.
'polish' can be an answer for 'buff' (I've seen this before). I am not certain of the 'chopin' bit.
'used by' is the link.
Can you help me to learn more?
(Other definitions for polish that I've seen before include "Beeswax, for example" , "Substance used to produce shine" , "Shine for a European" , "Shine up in Warsaw" , "taught in finishing school?" .)
