Bacon piece Arnold reviewed (6)
I believe the answer is:
lardon
'bacon piece' is the definition.
'lardon' can be an answer for 'piece' (I have seen 'piece of bacon' mean 'lardon' so perhaps 'piece' could also mean 'lardon'). I'm not sure about the 'bacon' bit.
'arnold reviewed' is the wordplay.
'reviewed' indicates an anagram (letters reviewed or revised).
'arnold' is an anagram of 'LARDON'.
Can you help me to learn more?
(Other definitions for lardon that I've seen before include "Strip or small cube of fatty bacon" , "bit of a roasting" , "Small piece of bacon used in cooking" , "Chunk of bacon" , "chunk of meat" .)
