Possibly rare piece to eat? (3)
I believe the answer is:
bit
'possibly rare piece' is the definition.
'bit' can be an answer for 'piece' (bit is a kind of piece). I am not sure about the 'possibly rare' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bit that I've seen before include "Unspoken" , "Small piece - used teeth" , "Boring tip of a drill" , "A little coin" , "something boring" .)
