High spirits, exhilaration (7)
I believe the answer is:
elation
I believe this is a double definition.
'high spirits' is the first definition.
(synonyms)
'exhilaration' is the second definition.
(I've seen this before)
(Other definitions for elation that I've seen before include "It's a great feeling!" , "Feeling of delight, joy" , "Euphoria of toenail" , "Feeling of joy and pride" , "There's great joy" .)
