City can start jangling (5)
I believe the answer is:
tinny
'jangling' is the definition.
(both can mean making a metallic sound)
'city can start' is the wordplay.
'city' becomes 'ny' (short for New York).
'can' becomes 'tin' (both are metal containers).
'start' is a charade indicator (letters next to each other).
'ny' put after 'tin' is 'TINNY'.
(Other definitions for tinny that I've seen before include "Aussie beer" , "Cheap" , "Shoddy" , "Sounding thin and metallic" , "Made of poor metal" .)
