Cherish sinner — he needs to reform (8)
I believe the answer is:
enshrine
'cherish' is the definition.
(I've seen this in another clue)
'sinner he needs to reform' is the wordplay.
'sinner he' anagrams to 'ENSHRINE'.
But, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for enshrine that I've seen before include "Preserve (something) in a form ensuring respect" , "Preserve and cherish as in holy place" , "Hold sacred - protect" , "Treasure" , "Preserve (an idea) so that it will be respected" .)
