An excerpt from Poulenc or Elgar that's requested by the audience (6)
I believe the answer is:
encore
'the audience' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'an excerpt from poulenc or elgar that's requested' is the wordplay.
'ENCORE' is hidden in amongst the letters.
But, I'm not sure how the hidden word is indicated.
'by' is the link.
Can you help me to learn more?
(Other definitions for encore that I've seen before include "Play it again, Sam?" , "We need more" , "Call for additional item" , "Request for repeat performance" , "Repeat performance, please" .)
