What would enhance the sound of new opera he composed? (8)
I believe the answer is:
earphone
'what would enhance the sound of new opera he composed?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'new opera he composed?' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'composed?' is an anagram indicator.
'n'+'opera'+'he'='noperahe'
'noperahe' anagrammed gives 'EARPHONE'.
Can you help me to learn more?
(Other definitions for earphone that I've seen before include "Device for private listening" , "Audio receiver" , "Through which to hear privately" , "in which music can be heard" , "Hope near (anag)" .)
