As reported from every quarter, perhaps (4)
I believe the answer is:
news
'as' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'reported from every quarter perhaps' is the wordplay.
I cannot really understand how this works, but
'from' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
'quarter' could be 'nw' and 'nw' is found in the remaining letters.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for news that I've seen before include "Reports on current affairs" , "Intelligence, information" , "Contents of bulletin" , "Hitherto unknown info" , "that's aired at six o'clock" .)
