"Fire away" (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
ask
'fire away' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ask that I've seen before include "Put a question" , "Something demanded" , "Request, invite" , "Inquire" , "Issue invitations" .)
