Very quiet India-blue arrangement (9)
I believe the answer is:
inaudible
'very quiet' is the definition.
'inaudible' can be an answer for 'quiet' (associated in meaning). I am not certain of the 'very' bit.
'india-blue arrangement' is the wordplay.
'arrangement' indicates an anagram.
'india'+'blue'='indiablue'
'indiablue' is an anagram of 'INAUDIBLE'.
Can you help me to learn more?
(Other definitions for inaudible that I've seen before include "Cannot be heard" , "Unable to be heard" , "Impossible to hear" , "Not aurally detectible" , "impossible to grasp" .)
