Anger, possibly hate (4)

I believe the answer is:

heat

'anger' is the definition.
(thesaurus)

'possibly hate' is the wordplay.
'possibly' is an anagram indicator.
'hate' with letters rearranged gives 'HEAT'.

(Other definitions for heat that I've seen before include "Preliminary round in a contest" , "Apply warmth" , "Get agitated" , "Toast" , "Raise temperature" .)

I've seen this clue in the Evening Standard.
