Opening delight (8)
I believe the answer is:
entrance
I believe this clue is a double definition.
'opening' is the first definition.
(thesaurus)
'delight' is the second definition.
(thesaurus)
(Other definitions for entrance that I've seen before include "Way in - hypnotise" , "arrival" , "Hold" , "doorway" , "it's common, say, for some children to sit" .)
