He got Daniel to break the news (8)
I believe the answer is:
headline
'the 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?
'he got daniel to break' is the wordplay.
'got' means one lot of letters goes inside another.
'to break' indicates an anagram.
'daniel' with letters rearranged gives 'eadlin'.
'he' enclosing 'eadlin' is 'HEADLINE'.
Can you help me to learn more?
(Other definitions for headline that I've seen before include "streamer, perhaps" , "Newspaper title" , "Top (a concert bill)" , "Article title" , "Prominent text" .)
