Six on the table? Stir broiled meat (9)
I believe the answer is:
carbonado
'broiled meat' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'six on the table? stir' is the wordplay.
'six on the table?' becomes 'carbon' (I can't explain this - if you can you should give a lot more credence to this answer).
'stir' becomes 'ado' (synonyms).
'carbon'+'ado'='CARBONADO'
Can you help me to learn more?
(Other definitions for carbonado that I've seen before include "Meat grilled" , "Dark diamond used in industry for drilling and polishing" , "Beef stew; black diamond" .)
