Repugnant, detestable (9)
I believe the answer is:
abhorrent
I believe this is a double definition.
'repugnant' is the first definition.
(synonyms)
'detestable' is the second definition.

(Other definitions for abhorrent that I've seen before include "Repulsive" , "horrid" , "Disgusting, loathsome" , "Detestable, really off-putting" , "Detestable, loathsome" .)
