A revolting subject (5)
I believe the answer is:
rebel
'a revolting subject' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for rebel that I've seen before include "Bolshy" , "James Dean was one without a cause" , "Revolt, mutiny" , "One refusing to conform" , "Freedom fighter?" .)
