Have won redress (3)
I believe the answer is:
own
'have' is the definition.
(to have something is to own it)
'won redress' is the wordplay.
'won' can be anagrammed to 'OWN'.
But, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for own that I've seen before include "Private" , "Posses" , "Personal; possess" , "Be in legal possession of (3)" , "Allow" .)
