Avoid blocking sound channel with axis ambassador (8)
I believe the answer is:
emissary
'ambassador' is the definition.
(I've seen this in another clue)
'avoid blocking sound channel with axis' is the wordplay.
'avoid' becomes 'miss' (miss can mean to avoid).
'blocking' indicates putting letters inside.
'sound channel with' becomes 'ear' (I can't justify this - if you can you should give a lot more credence to this answer).
'axis' becomes 'Y'.
'miss' going within 'ear' is 'emissar'.
'emissar'+'y'='EMISSARY'
Can you help me to learn more?
(Other definitions for emissary that I've seen before include "Government messenger" , "Delegate" , "Representative on special mission" , "I'm sent!" , "Spy" .)
