Meat; gripe (4)
I believe the answer is:
beef
This clue is a double definition.
'meat' is the first definition.
(I know that Beef is a type of meat)
'gripe' is the second definition.
(I know this)
(Other definitions for beef that I've seen before include "Bovine flesh" , "Grouse - meat" , "See 24" , "Meat - complaint" , "Strength - grievance" .)
