Tidied and made a pile from (7,2)
I believe the answer is:
cleaned up
'tidied' is the definition.
('clean up' can be a synonym of 'tidy')
'made a pile from' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for cleaned up that I've seen before include "what the charlady did" , "Put in order - gained financially" , "'Hit the Jackpot'" , "Made a substantial profit" , "Expurgated" .)
