Clear one must be accepted, being under doctor’s care (7)
I believe the answer is:
patient
'under doctor's care' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'clear one must be accepted' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'clear' could be 'patent' (synonyms) and 'patent' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'being' is the link.
Can you help me to learn more?
(Other definitions for patient that I've seen before include "Unhurried" , "Long-suffering - one under treatment" , "convalescent" , "Willing to wait" , "one of interest to medics?" .)
