Public appearance divorcee guaranteed after surgery to back (8)
I believe the answer is:
exposure
'public appearance' is the definition.
'exposure' can be an answer for 'appearance' (thesaurus). I am not sure about the 'public' bit.
'divorcee guaranteed after surgery to back' is the wordplay.
'divorcee' becomes 'ex' (I've seen this in other clues).
'guaranteed' becomes 'sure' (I've seen this in other clues).
'after' means one lot of letters go next to another.
'surgery' becomes 'op' (short for operation).
'to back' shows that the letters should be reversed in order.
'op' back-to-front is 'po'.
'sure' put after 'po' is 'posure'.
'ex'+'posure'='EXPOSURE'
Can you help me to learn more?
(Other definitions for exposure that I've seen before include "Lack of cover" , "being unmasked" , "Lack of shelter" , "Unveiling" , "Disclosure - made by a photographer?" .)
