Complain tearfully (6)
I believe the answer is:
snivel
'complain tearfully' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for snivel that I've seen before include "Cry in whining way, whinge" , "Whine (with a runny nose?)" , "Whine tearfully (through the nose?)" , "Blubber contemptibly" , "Sniff - whine" .)
