Officers charged to find source of supplies (7,5)
I believe the answer is:
general store
'source of supplies' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'officers charged' is the wordplay.
'officers' becomes 'generals' (general is a kind of officer).
'charged' becomes 'tore' (tear can mean to charge around).
'generals'+'tore'='GENERAL STORE'
'to find' is the link.
Can you help me to learn more?
(Other definitions for general store that I've seen before include "Shop carrying a broad range of goods" , "trading post" , "village shop" , "Shop selling miscellaneous range of goods" , "Retail outlet" .)
