Game -- approve of meat (10)
I believe the answer is:
backgammon
'game' is the definition.
(I know that backgammon is a type of board game)
'approve of meat' is the wordplay.
'approve' becomes 'back' (backing is a kind of approving).
'of meat' becomes 'gammon' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'back'+'gammon'='BACKGAMMON'
Can you help me to learn more?
(Other definitions for backgammon that I've seen before include "dicey contest" , "Game with 24 points" , "sedentary activity" , "Board game played with dice" , "Dice and counter game" .)
