Husband stocks food shop in capital territory (5)
I believe the answer is:
delhi
'capital territory' is the definition.
(National Capital Territory of India)
'husband stocks food shop in' is the wordplay.
'husband stocks' becomes 'h' (I can't justify this - if you can you should give a lot more credence to this answer).
'food shop' becomes 'deli' (short for delicatessen).
'in' indicates putting letters inside.
'h' inserted inside 'deli' is 'DELHI'.
Can you help me to learn more?
(Other definitions for delhi that I've seen before include "Old city of north central India" , "New -, Asian capital" , "Indian state" , "Ancient city" , "Capital at one time" .)
