2 complaint (6)
I believe the answer is:
grouse
This clue could be a double definition.
'2' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'complaint' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for grouse that I've seen before include "The complaint of a gamebird" , "No shooting it before 12 August" , "Game bird - beef" , "See game bird" , "Bird - complaint" .)
