Revolution helping to suppress religious work (8)
I believe the answer is:
rotation
'revolution' is the definition.
(I know that revolution can be written as rotation)
'helping to suppress religious work' is the wordplay.
'helping' becomes 'ration' (a ration is a serving or helping).
'to suppress' means one lot of letters goes inside another.
'religious work' becomes 'ot' (I can't justify this - if you can you should believe this answer much more).
'ration' going around 'ot' is 'ROTATION'.
Can you help me to learn more?
(Other definitions for rotation that I've seen before include "Recurring sequence" , "Process of turning" , "Spinning motion or cyclic changes as of crops" , "Recurrent order" , "Revolutionary movement" .)
