News of firing? (7)
I believe the answer is:
reports
'news of firing?' is the definition.
Although both the answer and 'firing?' are verbs, they are not in the same form of the verb.
'news of firing?' is the wordplay.
'news' becomes 'report' (report is a kind of news).
'of firing?' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'report'+'s'='REPORTS'
Can you help me to learn more?
(Other definitions for reports that I've seen before include "Documents describing findings" , "that follow the shooting?" , "News stories" , "News items" , "Sounds of gunfire" .)
