Bad conditions for forging steel (5)
I believe the answer is:
sleet
'bad conditions for' is the definition.
The definition suggests a singular noun which matches the answer.
'forging steel' is the wordplay.
'forging' is an anagram indicator (I've seen this in other clues).
'steel' is an anagram of 'SLEET'.
Can you help me to learn more?
(Other definitions for sleet that I've seen before include "unpleasant weather" , "Snowy rain" , "Icy rain" , "Cold precipitation" , "Partly melted falling 16 across or 18 down" .)
