Repugnance, revulsion (6)
I believe the answer is:
horror
I believe this clue is a double definition.
'repugnance' is the first definition.
(I know that repugnance can be written as horror)
'revulsion' is the second definition.
(I know that revulsion can be written as horror)
(Other definitions for horror that I've seen before include "Extreme fear or revulsion" , "The Rocky -- Show" , "Intense and profound fear" , "Feeling of loathing and fear" , "Hatred, dismay; film genre" .)
