Betrayed but not executed? (6)
I believe the answer is:
undone
'betrayed' is the definition.
Although both the answer and definition are past participle verbs, I cannot understand how they can define each other.
'not executed?' is the wordplay.
'not' becomes 'un' (prefix meaning 'not').
'executed?' becomes 'done' (execute can mean to do or accomplish).
'un'+'done'='UNDONE'
'but' is the link.
Can you help me to learn more?
(Other definitions for undone that I've seen before include "Ruined - no longer fastened" , "Not finished; ruined" , "Not finished; untied" , "Not bound" , "Annulled; untied" .)
