Form of government that may make one go charily (9)
I believe the answer is:
oligarchy
'form of government' is the definition.
(oligarchy is a kind of form of government)
'may make one go charily' is the wordplay.
'go charily' can be anagrammed to 'OLIGARCHY'.
Though, I'm unsure how the anagram is indicated.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for oligarchy that I've seen before include "a few men in government" , "Form of government with power held by a few" , "Rule of the few" , "Government by small elite" , "Political system of government by a few people" .)
