Wild with excitement (9)
I believe the answer is:
delirious
'wild with excitement' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for delirious that I've seen before include "Frenzied" , "Ecstatic" , "In wild ecstasy" , "In a state of wild excitement" , "Highly excited - hallucinating" .)
