Unqualified medic is poor performer in hospital (6)
I believe the answer is:
shaman
'unqualified medic' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'poor performer in hospital' is the wordplay.
'poor performer' becomes 'ham' (I've seen this in another clue).
'in' is an insertion indicator.
'hospital' becomes 'san' (short for sanatorium).
'ham' put inside 'san' is 'SHAMAN'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for shaman that I've seen before include "Tribal medicine man" , "who practises a form of spiritualism?" , "Medium between the visible and spirit worlds" , "Asian doctor-priest" , "Sorcerer" .)
