Made trouble, surrounded by the capacity to believe (7)
I believe the answer is:
created
'made' is the definition.
('create' can be a synonym of 'make')
'trouble surrounded by the capacity to believe' is the wordplay.
I cannot quite understand how this works, but
'by' could be 'at' and 'at' is found within the answer.
The remaining letters 'creed' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for created that I've seen before include "Devised" , "Originated" , "Made, generated" , "Made a fuss" , "Brought into existence" .)
