Staff concealing a title for man, a strict disciplinarian (6)
I believe the answer is:
ramrod
'a strict disciplinarian' is the definition.
(I've seen this before)
'staff concealing a title for man' is the wordplay.
'staff' becomes 'rod' (both can mean a pole or stick).
'concealing' indicates putting letters inside.
'a title for man' becomes 'amr' (I can't justify this - if you can you should believe this answer much more).
'rod' enclosing 'amr' is 'RAMROD'.
Can you help me to learn more?
(Other definitions for ramrod that I've seen before include "Cannoneer's tool" , "Strict disciplinarian" , "Someone stern and inflexible - it was used with a musket" , "one into guns?" , "It's used to push a charge into a firearm" .)
