Bringing rain, it envelops half of us in shivering cold (5)
I believe the answer is:
cloud
'bringing rain it envelops' is the definition.
I can't tell whether this definition defines the answer.
'half of us in shivering cold' is the wordplay.
'half of' suggests halving the letters.
'in' means one lot of letters goes inside another.
'shivering' indicates anagramming the letters.
'us' cut in half is 'u'.
'cold' is an anagram of 'clod'.
'u' inserted inside 'clod' is 'CLOUD'.
Can you help me to learn more?
(Other definitions for cloud that I've seen before include "E.g. stratus" , "Eg, cumulus" , "Make less transparent" , "Visible mass floating above" , "Make less clear" .)
