No longer blue, having made a lot of money (7,2)
I believe the answer is:
cleaned up
'no longer blue' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs sometimes define each other.
'made a lot of money' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is found within the answer.
'lot' could be 'd' and 'd' is located in the answer.
'money' could be 'p' and 'p' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'having' acts as a link.
Can you help me to learn more?
(Other definitions for cleaned up that I've seen before include "'Hit the Jackpot'" , "Made a substantial profit" , "Put in order - gained financially" , "Got rid of dirt - made big profit" , "what the charlady did" .)
