In street, sheltered from wind, rain and snow combined (5)
I believe the answer is:
sleet
'wind rain and snow combined' is the definition.
I can't judge whether this definition defines the answer.
'in street sheltered' is the wordplay.
'in' means one lot of letters goes inside another.
'street' becomes 'st' (abbreviation).
'sheltered' becomes 'lee' (as in lee side, the side sheltered from wind).
'st' enclosing 'lee' is 'SLEET'.
'from' is the link.
Can you help me to learn more?
(Other definitions for sleet that I've seen before include "unpleasant weather" , "Partly frozen rain" , "Partly melted falling snow or hail" , "Partially frozen rain" , "Wintry precipitation" .)
