Ruined, as is the next clue? (6)
I believe the answer is:
dashed
'ruined' is the definition.
(dash can mean to ruin or destroy)
'as is the next clue?' is the wordplay.
I cannot really understand how this works, but
'as' is within the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for dashed that I've seen before include "Ran quickly, rushed" , "Frustrated" , "completely spoiled" , "Threw down or ran fast" , "Rushed; destroyed" .)
