Brussels, say, putting money into small arts organisation - quite the opposite (9)
I believe the answer is:
brassicas
'money into small arts organisation quite the opposite' is the definition.
I can't tell whether this defines the answer.
'brussels say' is the wordplay.
'brussels' becomes 'brassic' (I can't explain this - if you can you should believe this answer much more).
'say' becomes 'as' (I've seen this in other clues).
'brassic'+'as'='BRASSICAS'
'putting' acts as a link.
Can you help me to learn more?
(Other definitions for brassicas that I've seen before include "Plants" , "Swedes, for example" .)
