What does vane mean?
A vane is a rotating pointer or indicator, typically with a flat or curved surface, used to show direction or indicate a change in a system. In a broader sense, a vane can also refer to a blade or a flat surface that is used to deflect or change the direction of a fluid or gas.
Example
"The windmill's vane spun rapidly in the strong gusts, indicating the direction of the wind."
