Scattered on the ground like drifting snow (4)
I believe the answer is:
sown
'scattered on the ground' is the definition.
'sown' can be an answer for 'scattered' (I've seen this in another clue). I am not certain of the 'on the ground' bit.
'drifting snow' is the wordplay.
'drifting' is an anagram indicator.
'snow' is an anagram of 'SOWN'.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for sown that I've seen before include "(Of seeds) planted" , "set out to grow" , "Placed in ground as seed" , "Broadcast" , "(Of seed) planted" .)
