Look with astonishment, at this box? (6)
I believe the answer is:
goggle
'look' is the definition.
(goggling is a kind of looking)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for goggle that I've seen before include "wonder" , "Hit, beat (archaic)" , "Stare wide-eyed in amazement" , "Look in amazement with wide open eyes" .)
