Chap with a masterly way? (3)
I believe the answer is:
man
'chap' is the definition.
(chap can mean a man)
'with a masterly way?' is the wordplay.
'with' indicates putting letters inside.
'masterly way?' becomes 'mn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a' inserted into 'mn' is 'MAN'.
Can you help me to learn more?
(Other definitions for man that I've seen before include "Bishop, perhaps" , "race" , "Bloke" , "us?" , "Adult human male" .)
