Beef you can buy for about a pound a pound? (5)
I believe the answer is:
bully
'beef' is the definition.
(bully beef is corned beef)
'for about a pound a pound?' is the wordplay.
'for' becomes 'buy' (I can't explain this - if you can you should believe this answer much more).
'about' means one lot of letters goes inside another.
'a pound' becomes 'L' (the pound sign is based on an L).
'a pound?' becomes 'L' (abbreviation e.g. Lsd - pounds, shillings, pence).
'l'+'l'='ll'
'buy' placed around '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" .)
