Enthusiastic to geographically ignore Caerphilly (4)
I believe the answer is:
agog
'enthusiastic' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for agog that I've seen before include "Eagerly awaiting" , "State of wide-eyed wonder" , "Wide-eyed and fascinated" , "Excitedly interested" , "In a highly excited state" .)
