Reviled unfortunately in hand over (7)
I believe the answer is:
deliver
'hand over' is the definition.
(synonyms)
'reviled unfortunately' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'reviled' with letters rearranged gives 'DELIVER'.
'in' acts as a link.
(Other definitions for deliver that I've seen before include "Consign" , "bear" , "Bring (letters, etc)" , "Hand over (letter)" , "Hand over - release" .)
