Wren possibly poking bill into live circuit ends (9)
I believe the answer is:
architect
'wren' is the definition.
(I've seen this before)
'poking bill into live circuit ends' is the wordplay.
I cannot quite see how this works, but
'bill' could be 'chit' (chit is a kind of bill) and 'chit' is present in the answer.
'live' could be 'are' ('they live' means 'they are') and 'are' is present in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for architect that I've seen before include "Perhaps Scott" , "Author" , "Building designer" , "Wren perhaps" , "Designer of buildings" .)
