Betrayed with German individual (6)
I believe the answer is:
undone
'betrayed' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how one could define the other.
'with german individual' is the wordplay.
'with german' becomes 'und' ('and' in German).
'individual' becomes 'one' (an individual is one person).
'und'+'one'='UNDONE'
Can you help me to learn more?
(Other definitions for undone that I've seen before include "Opened" , "Not bound" , "Ruined; not tied" , "Not finished; ruined" , "Brought to ruin or destruction - or not buttoned" .)
