Brain division church dissenter left with little hesitation (10)
I believe the answer is:
cerebellum
'brain division' is the definition.
The answer and definition can be both body parts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'church dissenter left with little hesitation' is the wordplay.
'church' becomes 'CE' (abbreviation for Church of England).
'dissenter' becomes 'rebel' (rebel is a kind of dissenter).
'left' becomes 'l' (common abbreviation).
'with' is a charade indicator (letters next to each other).
'little hesitation' becomes 'um'.
'ce'+'rebel'+'l'+'um'='CEREBELLUM'
Can you help me to learn more?
(Other definitions for cerebellum that I've seen before include "motor controller" , "bit of brain" , "part of the brain" .)
