Pointed item: observe cutter, did you say? (6)
I believe the answer is:
icicle
'say?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for icicle that I've seen before include "Hanging ice; stalactite" , "Frozen droplet" , "Hanging piece of frozen liquid" , "Spear of 23 down" , "A pentent spear of frozen water" .)
