A pile of snow - like an ice floe? (6)
I believe the answer is:
adrift
'snow like an ice floe?' is the definition.
I can't judge whether this definition defines the answer.
'a pile' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
The remaining letters 'drift' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for adrift that I've seen before include "not settled" , "Off course" , "Rudderless, astray" , "Floating unattached as at sea" , "Aimlessly floating" .)
