Something valuable, as arranged (5)
I believe the answer is:
asset
'something valuable' is the definition.
(I've seen this in another clue)
'as arranged' is the wordplay.
'arranged' becomes 'set' (similar in meaning).
'as'+'set'='ASSET'
(Other definitions for asset that I've seen before include "Valued item" , "virtue" , "A useful thing l" , "Plus point" , "Help" .)
