Left order for piece of liver (4)
I believe the answer is:
lobe
'piece of liver' is the definition.
'lobe' can be an answer for 'piece' (lobe is a kind of piece). I'm unsure of the 'of liver' bit.
'left order' is the wordplay.
'left' becomes 'L' (common abbreviation).
'order' becomes 'obe' (Order of the British Empire award).
'l'+'obe'='LOBE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for lobe that I've seen before include "part of brain" , "Base of ear" , "Bottom part of ear" , "Leaf division" , "Part of ear or leaf" .)
