Relating to the sound of coins rattling? (5)
I believe the answer is:
sonic
'relating to the sound' is the definition.
I can't judge whether this definition defines the answer.
'coins rattling?' is the wordplay.
'rattling?' is an anagram indicator (letters rattle around).
'coins' is an anagram of 'SONIC'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for sonic that I've seen before include "Kind of boom" , "Relating to sound waves" , "Type of boom" , "seven hundred and forty three mph!" , "Employing sound" .)
