Operate election involving the Church? That’s where things will come home to roost (8)
I believe the answer is:
dovecote
'roost' is the definition.
(thesaurus)
'operate election involving the church? that's where things will come home' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'come' could be 'do' (synonyms) and 'do' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for dovecote that I've seen before include "Shelter for domesticated pigeons" , "Domestic bird shelter" , "Home for domesticated pigeons" .)
