Bullet that meant goodbye for someone? (7,4)
I believe the answer is:
parting shot
'bullet that meant' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'goodbye for someone?' is the wordplay.
'goodbye for' becomes 'parting' (I can't justify this - if you can you should believe this answer much more).
'someone?' becomes 'shot' (shot is a kind of someone).
'parting'+'shot'='PARTING SHOT'
Can you help me to learn more?
(Another definition for parting shot that I've seen is " Cutting remark on leaving".)
