Wanders aimlessly in the snow? (6)
I believe the answer is:
drifts
'wanders aimlessly' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for drifts that I've seen before include "mine passages" , "problems with snow" , "Floats along aimlessly" , "Moves slowly, carried by a current of air or water" , "Heaps of snow blown by the wind" .)
