Theatre agent returning after the opening of Amadeus to change the backdrop (7)
I believe the answer is:
repaper
'to change the backdrop' is the definition.
I can't judge whether this defines the answer.
'theatre agent returning after the opening of amadeus' is the wordplay.
'theatre' becomes 'rep' (repertory theatre).
'agent' becomes 'rep' (short for representative).
'returning' says the letters should be written backwards.
'after' means one lot of letters go next to another.
'the opening of' suggests taking the first letters.
The first letter of 'amadeus' is 'a'.
'rep' written backwards gives 'per'.
'per' after 'a' is 'aper'.
'rep'+'aper'='REPAPER'
Can you help me to learn more?
(Other definitions for repaper that I've seen before include "renew wall-covering" , "Decorate again (palindrome)" , "Cover walls again" , "Decorate walls again" , "Apply new wall covering" .)
