Voices here beginning to resound, organised in epic style (6,5)
I believe the answer is:
heroic verse
'epic style' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'voices here beginning to resound organised' is the wordplay.
'beginning to' indicates taking the first letters.
'organised' indicates an anagram.
The initial letter of 'resound' is 'r'.
'voices'+'here'+'r'='voicesherer'
'voicesherer' anagrammed gives 'HEROIC VERSE'.
'in' acts as a link.
Can you help me to learn more?
(Another definition for heroic verse that I've seen is " Epic style of poetry".)
