Hatred is over and almost dissipated (8)
I believe the answer is:
aversion
'hatred' is the definition.
(thesaurus)
'is over and almost dissipated' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'dissipated' is an anagram indicator.
'is'+'over'+'and'='isoverand'
'isoverand' with its final letter taken away is 'isoveran'.
'isoveran' is an anagram of 'AVERSION'.
(Other definitions for aversion that I've seen before include "Disgust" , "A version of strong dislike" , "Abhorrence - loathing" , "Hate" , "Strong dislike for, makes you look away" .)
