Club in Milan shifted painter to rendering (14)
I believe the answer is:
'rendering' is the definition.
('interpretation' can be a synonym of 'rendering')
'club in milan shifted painter to' is the wordplay.
'club in milan' becomes 'inter' (I can't justify this - if you can you should give a lot more credence to this answer).
'shifted' indicates anagramming the letters.
'painterto' is an anagram of 'pretation'.
Can you help me to learn more?
(Other definitions for interpretation that I've seen before include "Analysis" , "Way of explaining" , "Individual delivery of a dramatic role" .)
