Chain tsar in revolution? One might do it (9)
I believe the answer is:
anarchist
'one might do it' is the definition.
I can't judge whether this definition defines the answer.
'chain tsar in revolution?' is the wordplay.
'in revolution?' is an anagram indicator.
'chain'+'tsar'='chaintsar'
'chaintsar' is an anagram of 'ANARCHIST'.
Can you help me to learn more?
(Other definitions for anarchist that I've seen before include "supporter of lawlessness" , "Opponent of government" , "disorderly person" , "One who wishes to abolish all government" , "revolting type?" .)
