East German is framed by trial and put on the blacklist (9)
I believe the answer is:
ostracise
'put on the blacklist' is the definition.
'ostracise' can be an answer for 'blacklist' (I've seen this before). I'm unsure of the 'put on the' bit.
'east german is framed by trial' is the wordplay.
'east german' becomes 'ost' ('east' in German).
'framed by' indicates putting letters inside.
'trial' becomes 'race' (I can't justify this - if you can you should believe this answer much more).
'is' going within 'race' is 'racise'.
'ost'+'racise'='OSTRACISE'
'and' is the link.
Can you help me to learn more?
(Other definitions for ostracise that I've seen before include "cut off" , "Blacklist" , "I, Socrates may exclude from group" , "Cast out, blackball" , "Banish, blackball" .)
