Delight at confined bears (9)
I believe the answer is:
captivate
'delight' is the definition.
(I've seen this before)
'at confined bears' is the wordplay.
'confined' becomes 'captive' (synonyms).
'bears' indicates putting letters inside (some letters carry or bear others).
'at' placed inside 'captive' is 'CAPTIVATE'.
(Other definitions for captivate that I've seen before include "Entrance" , "Fascinate completely" , "Delight" , "Charm" , "Enchant" .)
