Feature of weather broadcast about north (4)
I believe the answer is:
snow
'feature of weather' is the definition.
'snow' can be an answer for 'weather' (snow is a kind of weather). I'm not certain of the 'feature of' bit.
'broadcast about north' is the wordplay.
'broadcast' becomes 'sow' (sowing is a kind of broadcasting).
'about' means one lot of letters goes inside another.
'north' becomes 'N' (abbreviation).
'sow' enclosing 'n' is 'SNOW'.
Can you help me to learn more?
(Other definitions for snow that I've seen before include "White specks on screen resulting from interference" , "Winter weather" , "Ice crystal precipitation" , "Frozen rain" , "Flakes overhead" .)
