The consequence of firing in the air? (6)
I believe the answer is:
upshot
'the consequence' is the definition.
('upshot' can be a synonym of 'consequence')
'firing in the air?' is the wordplay.
I cannot really understand how this works, but
'in the air?' could be 'up' and 'up' is found in the answer.
The remaining letters 'shot' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for upshot that I've seen before include "Event" , "issue" , "anti-aircraft fire?" , "skier" , "Outcome, consequence" .)
