Chap, shall we say? (4)
I believe the answer is:
chew
'say?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'chap shall we' is the wordplay.
I cannot quite see how this works, but
'chap' could be 'hew' and 'hew' is located in the answer.
A single letter 'c' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for chew that I've seen before include "Work or grind between teeth" , "Bite repeatedly" , "bit of tobacco" , "Munch" , "Prepare to swallow" .)
