Echo again to the noise of
I believe the answer is:
resound
'echo' is the definition.
(I've seen this before)
'again to the noise of' is the wordplay.
I cannot quite understand how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is located in the answer.
'noise' could be 'sound' (I've seen this in another clue) and 'sound' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for resound that I've seen before include "Reverberate" , "ring" , "Echo" .)
