Accursed (6)
I believe the answer is:
damned
'accursed' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for damned that I've seen before include "Abominable" , "Consigned to everlasting punishment" , "Consigned to hell or perdition" , "Mad Ned was doomed" , "Condemned to Hell" .)
