News of some gunfire? (7)
I believe the answer is:
reports
'gunfire?' is the definition.
Although both the answer and definition are nouns, they are not in the same form of the noun.
'news of some' is the wordplay.
'news' becomes 'report' (report is a kind of news).
'of some' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'report'+'s'='REPORTS'
Can you help me to learn more?
(Other definitions for reports that I've seen before include "Short accounts of the news" , "News stories" , "Statements" , "Sounds of gunfire" , "Writes about, booms" .)
