A performer makes it produce rapturous delight (8)
I believe the answer is:
entrance
'delight' is the definition.
(I've seen this in another clue)
'a performer makes it produce rapturous' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is found within the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for entrance that I've seen before include "Ingress" , "Way in - fascinate" , "doorway" , "it's common, say, for some children to sit" , "arrival" .)
