'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.

'i'+'can'+'report'+'it'='icanreportit'
'icanreportit' with letters rearranged gives 'PRACTITIONER'.

Can you help me to learn more?
