Doctor made needy misfit flush (7)
I believe the answer is:
moneyed
'misfit flush' is the definition.
'moneyed' can be an answer for 'flush' (I've seen this before). I'm not sure about the 'misfit' bit.
'doctor made needy' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'made' indicates anagramming the letters.
'needy' anagrammed gives 'neyed'.
'mo'+'neyed'='MONEYED'
Can you help me to learn more?
(Other definitions for moneyed that I've seen before include "Rich" , "Well-off" , "Well-heeled" , "Wealthy" , "rolling in it" .)
