A quiet intermission around end of recital — then this erupts? (8)
I believe the answer is:
applause
'this erupts?' is the definition.
The definition suggests a singular noun which matches the answer.
'a quiet intermission around end of recital' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'intermission' becomes 'pause' (synonyms).
'around' is an insertion indicator.
'end of' indicates one should take the final letters.
The last letter of 'recital' is 'l'.
'pause' enclosing 'l' is 'plause'.
'a'+'p'+'plause'='APPLAUSE'
'then' is the link.
Can you help me to learn more?
(Other definitions for applause that I've seen before include "round, perhaps?" , "Appreciative round?" , "Noisy expression of approbation" , "Approval expressed by clapping" , "Approving clap" .)
