Gobble (3)
I believe the answer is:
eat
'gobble' is the definition.
(I know that gobble is a kind of eat)
This is the entire clue.
(Other definitions for eat that I've seen before include "Dine in a restaurant" , "Use a knife and fork" , "and 27: Be humiliated" , "Have 23d [MEAL]" , "Be corrosive" .)
