See certain plants sold at the butcher's! (5)
I believe the answer is:
chops
'plants sold at the butcher's' is the definition.
I can't tell whether this definition defines the answer.
'see certain' is the wordplay.
'see' becomes 'C' (the word for the letter, according to Chambers).
'certain' becomes 'hops' (I can't explain this - if you can you should give a lot more credence to this answer).
'c'+'hops'='CHOPS'
Can you help me to learn more?
(Other definitions for chops that I've seen before include "Hacks" , "Axes" , "Cuts; slices of meat" , "Cuts of meat including part of a rib" , "trap" .)
