anem(o)-

The wind.

Greek anemos, wind.

This prefix is most commonly encountered in the anemometer, an instrument for measuring the speed of the wind. In botany, an anemophilous (Greek philos, loving) plant is one that is pollinated by the wind. The name of the anemone comes from the Greek word meaning windflower (a name the plant sometimes has in English), so called because it was thought the flowers open only when the wind blows.
