Rendered drunk (9)
I believe the answer is:
plastered
I believe this clue is a double definition.
'rendered' is the first definition.
(I've seen this before)
'drunk' is the second definition.
(slang term)
(Other definitions for plastered that I've seen before include "Smashed" , "Paralytic (slang)" , "Drunk - applied coating to a wall" , "Coated thickly, being slangily drunk" , "Pickled" .)
