Beef you can buy for about a pound a pound? (5)
I believe the answer is:
bully
'beef' is the definition.
(bully beef is a kind of beef)
'for about a pound a pound?' is the wordplay.
'for' becomes 'buy' (I can't justify this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'a pound' becomes 'l'.
'a pound?' becomes 'l'.
'l'+'l'='ll'
'buy' enclosing 'll' is 'BULLY'.
'you can buy' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for bully that I've seen before include "Intimidating person" , "excellent" , "Beef cured or pickled in brine" , "Well done" , "Playground thug" .)
