Artist initially stopped by copper over album "Flipping Nonsense" (8)
I believe the answer is:
sculptor
'artist' is the definition.
(I know that sculptor is a type of artist)
'initially stopped by copper over album flipping nonsense' is the wordplay.
'initially stopped by copper over' becomes 'scu' (I can't explain this - if you can you should give a lot more credence to this answer).
'album' becomes 'LP' (abbreviation for a long-play record).
'flipping' shows that the letters should be reversed in order.
'nonsense' becomes 'rot' (rot can mean nonsense or rubbish).
'rot' in reverse letter order is 'tor'.
'scu'+'lp'+'tor'='SCULPTOR'
Can you help me to learn more?
(Other definitions for sculptor that I've seen before include "Figure maker" , "Maker of statues" , "John Behan or Henry Moore, say" , "A carver of statues" , "Creator of three-dimensional works of art" .)
