Information from all four corners? (4)
I believe the answer is:
news
'information' is the definition.
(I know that news is a type of information)
'from all four corners?' is the wordplay.
'from' becomes 'e' (I've seen this in other clues).
'all four' becomes 'nws' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'corners?' means one lot of letters goes inside another.
'e' placed into 'nws' is 'NEWS'.
Can you help me to learn more?
(Other definitions for news that I've seen before include "Latest info" , "Noteworthy information" , "Four points" , "Important information" , "Broadcast detailing recent events" .)
