Dotty blamed for disorder (6)
I believe the answer is:
bedlam
'disorder' is the definition.
(bedlam is a kind of disorder)
'dotty blamed' is the wordplay.
'dotty' indicates an anagram.
'blamed' is an anagram of 'BEDLAM'.
'for' acts as a link.
(Other definitions for bedlam that I've seen before include "Complete chaos" , "Blammed for uproar" , "State of extreme confusion and disorder" , "Blamed for deafening noise" , "commotion" .)
