Give up doctor resorted to in moment of change (7,5)
I believe the answer is:
turning point
'moment of change' is the definition.
'turning point' can be an answer for 'moment' (I have seen 'Critical moment ' mean 'turning point' so perhaps 'moment' could also mean 'turning point'). I am not sure about the 'of change' bit.
'give up doctor resorted to' is the wordplay.
I cannot really understand how this works, but
'give' could be 'turnin' (turning in is a kind of giving) and 'turnin' is located in the answer.
'doctor' could be 'point' (pointing is a kind of doctoring) and 'point' is found within the answer.
A single letter 'g' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for turning point that I've seen before include "entrance to side street?" , "Crisis" , "Critical moment" , "Time of decisive change" .)
