Full of anticipation
I believe the answer is:
agog
'full of anticipation' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for agog that I've seen before include "Eagerly awaiting" , "Eager and wide-eyed" , "Unable to wait" , "Wide-eyed and fascinated" , "In state of wide-eyed expectancy" .)
