Frozen winter feature (6)

I believe the answer is:

icicle

(Other definitions for icicle that I've seen before include "Hanging piece of frozen liquid" , "Hanging ice; stalactite" , "Frozen water stalactite" , "Hanging ice spike" , "Spear-like shape formed by the freezing of dripping water" .)

I've seen this clue in The Times.
