Medic who's training English poet to inject drug (8)
I believe the answer is:
houseman
'medic' is the definition.
(I know that houseman is a type of Dr.)
'training english poet to inject drug' is the wordplay.
I cannot quite understand how this works, but
'english' could be 'e' (abbreviation) and 'e' is found in the answer.
'poet' could be 'housman' (I've seen this before) and 'housman' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'who's' acts as a link.
Can you help me to learn more?
(Other definitions for houseman that I've seen before include "Junior hospital post" , "Intern" , "Junior doctor in US" , "Resident junior doctor in hospital - so humane" .)
