She cussed degenerate aristocrats (9)

I believe the answer is:

duchesses

'aristocrats' is the definition.
(duchess is a kind of aristocrat)

'she cussed degenerate' is the wordplay.
'degenerate' indicates an anagram.
'she'+'cussed'='shecussed'
'shecussed' anagrammed gives 'DUCHESSES'.

(Other definitions for duchesses that I've seen before include "ladies" , "aristocrats" .)
