Echo producer's touching part of speech (6)
I believe the answer is:
reverb
'echo producer's' is the definition.
'reverb' can be an answer for 'echo' (I've seen this before). I am not certain of the 'producer's' bit.
'touching part of speech' is the wordplay.
'touching' becomes 're' (re can mean touching or regarding).
'part of speech' becomes 'verb' (verb is a kind of part of speech in grammar).
're'+'verb'='REVERB'
Can you help me to learn more?
(Other definitions for reverb that I've seen before include "Echo effect applied to sound" , "Echoing device" , "Echo in music" , "Effect where amplified sound vibrates" , "Echoing effect" .)
