They are suspended in cold weather (7)
I believe the answer is:
icicles
'they' is the definition.
Both the definition and answer are plural nouns.
Maybe you can see an association between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for icicles that I've seen before include "'When ... hang by the wall / And Dick the shepherd blows his nail' (Shakespeare)" , "They hang by the wall (L.L.Lost)" , "Pendent spears of frozen water (7)" , "Frozen pendants" , "Frozen stalactites" .)
