Whine tearfully (6)
I believe the answer is:
snivel
'whine tearfully' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for snivel that I've seen before include "Complain whiningly" , "moan" , "Cry in whining way, whinge" , "Blubber contemptibly" , "Complain self-pityingly" .)
