Opera performance concealing adult point (8)
I believe the answer is:
turandot
'opera' is the definition.
(I've seen this before)
'performance concealing adult point' is the wordplay.
'performance' becomes 'turn' (turn is a kind of performance).
'concealing' is an insertion indicator.
'adult' becomes 'a'.
'point' becomes 'dot' ('dot' can be a synonym of 'point'**).
'turn' going around 'a' is 'turan'.
'turan'+'dot'='TURANDOT'
(Other definitions for turandot that I've seen before include "Opera by Puccini" , "18 [OPERA] 's" , "Puccini's Chinese opera" .)
