Medical expert’s door out of the court (6)
I believe the answer is:
doctor
'medical' is the definition.
(thesaurus)
'door out of the court' is the wordplay.
'out of' is an insertion indicator.
'the court' becomes 'ct'.
'door' placed around 'ct' is 'DOCTOR'.
'expert's' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for doctor that I've seen before include "Medical practitioner, for instance" , "Onshore breeze" , "change" , "Medical professional or university don" , "Adulterate; medic" .)
