Hostile extremists' denial made breaking news (8)
I believe the answer is:
headline
'breaking news' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'hostile extremists' denial made' is the wordplay.
'extremists'' means to remove the middle letters (I've seen 'extremists' mean this).
'made' is an anagram indicator.
'hostile' with its centre removed is 'he'.
'denial' is an anagram of 'adline'.
'he'+'adline'='HEADLINE'
Can you help me to learn more?
(Other definitions for headline that I've seen before include "streamer, perhaps" , "Largest newspaper text" , "Newspaper title" , "Prominent text" , "It's prominent in paper" .)
