Nosh (3)
I believe the answer is:
eat
'nosh' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eat that I've seen before include "Devour" , "Gobble up" , "and 27: Be humiliated" , "Dine in a restaurant" , "Do cats - bats? Do bats - cats? (Alice in Wonderland)" .)
