Theatrical worker or coordinator fails to get on air (6)
I believe the answer is:
doctor
'theatrical worker' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'coordinator fails to get on air' is the wordplay.
I cannot really understand how this works, but
'to' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'or' acts as a link.
Can you help me to learn more?
(Other definitions for doctor that I've seen before include "Falsify; quack" , "An apple a day keeps him away" , "Licensed medical practitioner" , "Medical specialist" , "Medical worker or holder of highest university degree" .)
