It's complicated to be a real doctor (9)
I believe the answer is:
elaborate
'it's complicated' is the definition.
(thesaurus)
'to be a real doctor' is the wordplay.
'doctor' indicates an anagram.
'to'+'be'+'a'+'real'='tobeareal'
'tobeareal' with letters rearranged gives 'ELABORATE'.
(Other definitions for elaborate that I've seen before include "with added detail" , "flesh out?" , "With many parts or details, maybe a pattern" , "involved" , "Work out or describe in detail" .)
