Belief is breaking enemy? (6)
I believe the answer is:
theism
'belief' is the definition.
(theism is a kind of belief)
'is breaking enemy?' is the wordplay.
'breaking' means one lot of letters goes inside another.
'enemy?' becomes 'them' (I can't explain this - if you can you should believe this answer much more).
'is' going inside 'them' is 'THEISM'.
Can you help me to learn more?
(Other definitions for theism that I've seen before include "Belief in existence of a God revealed to man" , "of faith" , "The doctrine or belief in the existence of a God or gods" , "Belief in a deity" , "Belief in a creator" .)
