Hatred is over and practically obliterated (8)
I believe the answer is:
aversion
'hatred' is the definition.
(I've seen this before)
'is over and practically obliterated' is the wordplay.
'practically' means to remove the last letter.
'obliterated' is an anagram indicator.
'is'+'over'+'and'='isoverand'
'isoverand' with its final letter taken off is 'isoveran'.
'isoveran' with letters rearranged gives 'AVERSION'.
(Other definitions for aversion that I've seen before include "A version of strong dislike" , "A strong dislike or repugnance" , "phobia" , "A strong dislike for something - turn away from it" , "Strong dislike for, makes you look away" .)
