Interns prevented incident (5)
I believe the answer is:
event
'incident' is the definition.
(an incident is an event or happening)
'interns prevented' is the wordplay.
'EVENT' is hidden within the letters.
However, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for event that I've seen before include "Affair" , "Sporting contest" , "pole vault maybe" , "match" , "major incident" .)
