Audible comment about pointlessness of selling things in blizzard conditions (5-3)
I believe the answer is:
white-out
'audible comment' is the definition.
Although both the answer and definition are verbs in their base form, I can't see 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 white-out that I've seen before include "Intense blizzard" , "Dense blizzard" .)
