Exuberance shown by senior ghosts? (4,7)
I believe the answer is:
high spirits
'exuberance' is the definition.
(thesaurus)
'shown by senior ghosts?' is the wordplay.
'shown by' says to put letters next to each other.
'senior' becomes 'high' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ghosts?' becomes 'spirits' (spirits of the dead).
'high' next to 'spirits' is 'HIGH SPIRITS'.
Can you help me to learn more?
(Other definitions for high spirits that I've seen before include "Elated frame of mind" , "Cheerful mood" .)
