Split a religious group led by some bigot (6)
I believe the answer is:
bisect
'split' is the definition.
(I've seen this before)
'a religious group led by some bigot' is the wordplay.
'a religious group' becomes 'sect' (I've seen this before).
'led by' is a charade indicator (letters next to each other).
'some bigot' becomes 'bi' (I can't explain this - if you can you should give a lot more credence to this answer).
'sect' put after 'bi' is 'BISECT'.
Can you help me to learn more?
(Other definitions for bisect that I've seen before include "Cut or divide in two" , "Halve (angle)" , "Divide into two equal parts" , "fork" , "equally split" .)
