Story heard in a moment (6)
I believe the answer is:
report
'story' is the definition.
(I know that story can be written as report)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for report that I've seen before include "Make a complaint about (someone)" , "Account, story" , "A loud bang, or an account" , "Formal statement" , "Make a formal complaint" .)
