Love or hate, say (7)
I believe the answer is:
emotion
This clue is a double definition.
'love' is the first definition.
(thesaurus)
'hate say' is the second definition.
(I know that hatred is a type of emotion)
(Other definitions for emotion that I've seen before include "A strong instinctive feeling" , "Anger, perhaps" , "Feeling such as joy, sorrow and fear" , "Agitation of mind" , "Surprise, perhaps" .)
