Withdraw for the doctor to attend to again (7)
I believe the answer is:
retreat
'withdraw' is the definition.
(I know that withdraw can be written as retreat)
'doctor to attend to again' is the wordplay.
I cannot quite understand how this works, but
'doctor' could be 'treat' (doctor can mean to give medical treatment) and 'treat' is located in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'for the' acts as a link.
Can you help me to learn more?
(Other definitions for retreat that I've seen before include "Go back" , "concession" , "retirement" , "Leave - refuge" , "Back away" .)
