Meet religious group to the east of Bury (9)
I believe the answer is:
intersect
'meet' is the definition.
(intersecting is a kind of meeting)
'religious group to the east of bury' is the wordplay.
'religious group' becomes 'sect' (I've seen this before).
'to the east of' says to put letters next to each other.
'bury' becomes 'inter' (synonyms).
'sect' after 'inter' is 'INTERSECT'.
(Other definitions for intersect that I've seen before include "Criss-cross" , "making one cross" , "Divide into parts" , "Cut across" , "Meet at a point" .)
