Atrocious, awful (8)
I believe the answer is:
horrible
I believe this is a double definition.
'atrocious' is the first definition.
(I know that atrocious can be written as horrible)
'awful' is the second definition.
(both can mean unpleasant)
(Other definitions for horrible that I've seen before include "Dreadful, awful" , "Nasty" , "Abhorrent" , "Revolting" , "Frightful, ugly" .)
