Which weather instrument measures wind speed?

Explanation:
Anemometer is the instrument used to measure wind speed. It typically has cups or a small propeller that catch the wind; the wind turning the cups or propeller drives the device, and the rotation rate is converted into a wind speed reading. This is different from a barometer, which measures air pressure; a thermometer, which measures temperature; and a hygrometer, which measures humidity. So anemometers specifically quantify how fast the air is moving.
