Asian money sound as a bell (4)
I believe the answer is:
dong
'sound as a bell' is the definition.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for dong that I've seen before include "Deep resonant clang - Vietnamese monetary unit" , "Lear's one had a luminous nose" , "The --- with a Luminous Nose (Lear)" , "Ding's partner?" , "Deep ringing sound" .)
