There's nothing evil in returning to her (5)
I believe the answer is:
olive
'her' is the definition.
'there's nothing evil in returning' is the wordplay.
I cannot quite see how this works, but
'nothing' could be 'o' (O resembles 0) and 'o' is present in the answer.
an anagram of 'evil' is 'live' which is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for olive that I've seen before include "Mediterranean tree-fruit - nice in martini" , "Yellow-green colour like Mediterranean fruit" , "Small green Mediterranean tree-fruit (5)" , "Greyish-green colour" , "It's branch is a symbol of peace" .)
