Talk in church (4)
I believe the answer is:
pray
'talk in church' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pray that I've seen before include "Call upon in supplication" , "Offer supplication" , "Make supplication (to a god)" , "Wish earnestly (for a particular outcome)" , "Commune with some spiritual power" .)
