Doctor playing I Spy with china (9)
I believe the answer is:
physician
'doctor' is the definition.
(I know that Physician is a type of doctor)
'playing i spy with china' is the wordplay.
'playing' indicates an anagram.
'with' says to put letters next to each other.
'i'+'spy'='ispy'
'ispy' after 'china' is 'chinaispy'.
'chinaispy' anagrammed gives 'PHYSICIAN'.
(Other definitions for physician that I've seen before include "Licensed medical practitioner" , "A doctor, as in ''........, heal thyself''" , "Medic" .)
