Doctor receiving education in charge of doctor (6)
I believe the answer is:
medico
'doctor' is the definition.
('medico' can be a synonym of 'doctor')
'doctor receiving education in charge' is the wordplay.
'doctor' becomes 'mo' (medical officer**).
'receiving' is an insertion indicator.
'education' becomes 'ed' (abbreviation - e.g. sex ed).
'in charge' becomes 'ic'.
'ed'+'ic'='edic'
'mo' going around 'edic' is 'MEDICO'.
'of' acts as a link.
(Other definitions for medico that I've seen before include "Health practitioner" , "quack" , "Doctor" .)
