One man's name for a gun? (7)
I believe the answer is:
brendan
'one man's' is the definition.
'name for a gun?' is the wordplay.
I cannot quite see how this works, but
'name' could be 'brenda' and 'brenda' is located in the answer.
A single letter 'n' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for brendan that I've seen before include "Early Irish saint" , "Chap" , "- Behan, Irish dramatist" , "-- Behan, Irish author" .)
