It's soft to eat, though not exactly pap (3)
I believe the answer is:
bap
'not exactly pap' is the definition.
I can't tell whether this defines the answer.
'it's soft to eat though' is the wordplay.
'it's soft' becomes 'b' (black, as opposed to H for hard in pencils).
'to' means one lot of letters go next to another.
'eat though' becomes 'ap' (I can't justify this - if you can you should believe this answer much more).
'b'+'ap'='BAP'
Can you help me to learn more?
(Other definitions for bap that I've seen before include "Flattish bread roll" , "Large flat round roll" , "A soft flat bread roll" , "Large soft bread roll" , "Big roll" .)
