Provide information about sound of gunshot (6)
I believe the answer is:
report
I believe this clue is a triple definition!
'provide information about' is the first definition.
(as in a reporting a crime)
'sound' is the second definition.
(report is a kind of sound)
'of' acts as a link.
'gunshot' is the third definition.
(I've seen this in another clue)
(Other definitions for report that I've seen before include "Make a complaint about (someone)" , "Statement of fact" , "Give an account" , "Account, story" , "Porter (anag.)" .)
