Not all crab apples can be eaten (3)
I believe the answer is:
bap
'be eaten' is the definition.
I can't tell whether this defines the answer.
'not all crab apples can' is the wordplay.
'not all' says the answer is hidden in the clue (only some of the letters).
'BAP' is hidden in the letters of 'crab apples can'.
Can you help me to learn more?
(Other definitions for bap that I've seen before include "Large flat round roll" , "Big roll" , "Large soft bread roll" , "A soft flat bread roll" , "Flattish bread roll" .)
