Dicky blamed in chaos (6)
I believe the answer is:
bedlam
'chaos' is the definition.
(synonyms)
'dicky blamed' is the wordplay.
'dicky' indicates an anagram (dicky can mean ill or non-functioning).
'blamed' with letters rearranged gives 'BEDLAM'.
'in' acts as a link.
(Other definitions for bedlam that I've seen before include "commotion" , "State of extreme confusion and uproar" , "Scene of uproar and disorder" , "hubbub" , "Blamed for 9 across? (8)" .)
