Sullied, or otherwise wronged (3-4)
I believe the answer is:
ill-used
'wronged' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'sullied or otherwise' is the wordplay.
'or otherwise' indicates anagramming the letters (I've seen this in other clues).
'sullied' is an anagram of 'ILL-USED'.
Can you help me to learn more?
(Other definitions for ill-used that I've seen before include "Maltreated" , "Badly treated, exploited" , "Mistreated" .)
