Spare piece of meat? (4)
I believe the answer is:
lean
This might be a double definition.
'spare piece' is the first definition.
'lean' can be an answer for 'spare' (I've seen this in another clue). I'm not certain of the 'piece' bit.
'meat?' is the second definition.
(I've seen this before)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for lean that I've seen before include "without success" , "Sir David - - (film director)" , "Spare - incline" , "Thin; rest (against)" , "With no fat; slope" .)
