Push something fragile away from the edge? (3,2)
I believe the answer is:
egg on
'push' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for egg on that I've seen before include "'Incite, urge (3,2)'" , "Encourage (someone to do a risky thing)" , "Fire" , "Push" , "Prod" .)
