Determined to do good again for the Editor (6)
I believe the answer is:
dogged
'determined' is the definition.
(thesaurus)
'do good again for the editor' is the wordplay.
'good again' becomes 'gg' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for' is a charade indicator (letters next to each other).
'the editor' becomes 'ed'.
'do'+'gg'+'ed'='DOGGED'
'to' is the link.
Can you help me to learn more?
(Other definitions for dogged that I've seen before include "Tenacious, persistent" , "Resolute, tenacious" , "Stubborn or determined in canine manner" , "Resolute; trailed" , "Stubbornly persistent in canine way" .)
