Beef with extra decoration added (5)
I believe the answer is:
baron
'beef' is the definition.
(baron is a joint of beef)
'extra decoration added' is the wordplay.
'extra' becomes 'b' (abbreviation for 'bye' - cricket).
'decoration' becomes 'aron' (I can't explain this - if you can you should give a lot more credence to this answer).
'added' means one lot of letters go next to another.
'b'+'aron'='BARON'
'with' is the link.
Can you help me to learn more?
(Other definitions for baron that I've seen before include "Aristocratic title" , "A lord; sounds like childless" , "British peer of the lowest rank" , "British peer; business mogul" , "captain of industry" .)
