See PI, etc in this exciting part of a play (3,5)
I believe the answer is:
set piece
'see pi etc in this exciting' is the definition.
The definition suggests a singular noun which matches the answer.
'part of a play' is the wordplay.
I cannot really see how this works, but
'part' could be 'piece' (synonyms) and 'piece' is found in the answer.
'play' could be 'set' (set is a kind of play) and 'set' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for set piece that I've seen before include "A rehearsed, impressive, manoeuvre" , "rehearsed play" , "well-rehearsed manoeuvre" , "Standard manoeuvre" , "Carefully prepared performance (from free kick?)" .)
