Teacher after caper cut piece of bacon or pork (6)
I believe the answer is:
lardon
'cut piece of bacon or pork' is the definition.
I can't tell whether this definition defines the answer.
'teacher after caper' is the wordplay.
'teacher' becomes 'don' (don can mean an academic - especially at Oxbridge).
'after' means one lot of letters go next to another.
'caper' becomes 'lar' (I can't justify this - if you can you should believe this answer much more).
'don' put after 'lar' is 'LARDON'.
Can you help me to learn more?
(Other definitions for lardon that I've seen before include "Strip of bacon for roasting meat" , "Small piece of bacon used in cooking" , "Chunk of bacon" , "Strip or small cube of fatty bacon" , "strip of fat" .)
