Reveal firearm, say, to traditional commander (6)
I believe the answer is:
shogun
'traditional commander' is the definition.
'shogun' can be an answer for 'commander' (I've seen this before). I am unsure of the 'traditional' bit.
'reveal firearm say' is the wordplay.
'reveal' becomes 'sho' (I can't justify this - if you can you should give a lot more credence to this answer).
'firearm say' becomes 'gun' (firearm is a kind of gun).
'sho'+'gun'='SHOGUN'
'to' is the link.
Can you help me to learn more?
(Other definitions for shogun that I've seen before include "Hereditary army commander in feudal Japan" , "Dominant Japanese" , "Hereditary Japanese military governor" , "Hereditary commander-in-chief in feudal Japan" , "Former military governor of Japan" .)
