Vicar has laser surgery down below in setback (8)
I believe the answer is:
reversal
'setback' is the definition.
(I know that setback can be written as reversal)
'vicar has laser surgery down below' is the wordplay.
I cannot really understand how this works, but
'vicar' could be 'rev' (short for reverend) and 'rev' is located in the answer.
an anagram of 'laser' is 'ersal' which is within the answer.
No letters remain.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for reversal that I've seen before include "Volte-face" , "Set back" , "U-turn" , "misfortune!" , "A set-back or turning around" .)
