Church with popular comedian giving chat (7)
I believe the answer is:
chinwag
'chat' is the definition.
(I've seen this before)
'church with popular comedian' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'with' is a charade indicator (letters next to each other).
'popular' becomes 'in'.
'comedian' becomes 'wag' (I've seen this before).
'ch'+'in'+'wag'='CHINWAG'
'giving' acts as a link.
(Other definitions for chinwag that I've seen before include "Appoint" , "Chat (slang)" , "Informal conversation" , "Informal chat moving lower jaw" , "rabbit" .)
