A gong that may barely clink (5)
I believe the answer is:
medal
'a gong' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for medal that I've seen before include "Prize; sounds like interfere" , "Commemorative disc" , "George Cross, for instance" , "Olympic award" , "Metal disc given as award" .)
