I can report it improved, doctor (12)
I believe the answer is:
'doctor' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'i can report it improved' is the wordplay.
'improved' indicates anagramming the letters.
'icanreportit' with letters rearranged gives 'PRACTITIONER'.
Can you help me to learn more?
(Other definitions for practitioner that I've seen before include "One involved in medicine, such as a GP" , "Professional person, esp. doctor" , "Trained professional" , "Person actively involved in a profession (especially medicine)" .)
