Born to carry a gun, though you say not (6)
I believe the answer is:
negate
'you say not' is the definition.
I can't judge whether this definition defines the answer.
'born to carry a gun' is the wordplay.
'born' becomes 'nee' (I've seen this before).
'to carry' means one lot of letters goes inside another.
'a gun' becomes 'gat' (gat is a kind of gun).
'nee' enclosing 'gat' is 'NEGATE'.
'though' is the link.
Can you help me to learn more?
(Other definitions for negate that I've seen before include "Age ten (anag)" , "Make invalid" , "disallow!" , "Discredit" , "Nullify - deny the existence of" .)
