Great joy, euphoria (7)
I believe the answer is:
elation
I believe this clue is a double definition.
'great joy' is the first definition.
(I've seen this in another clue)
'euphoria' is the second definition.
(I've seen this in another clue)
(Other definitions for elation that I've seen before include "Delight, thrill" , "exhibits successful pride" , "Feeling of intense delight" , "Transport" , "Feeling of joy and pride" .)
