remove weed

芸 is composed of the radical of 艸(grass) and 云(cloud). 艸 is the pictograph of two small blades of grass, indicating plants, while 云 is the pictograph of swirling cloud vapors and conveys the idea of rotation or repetition. Weeds in the fields grow continuously and must be removed over and over again so as not to hinder the growth of crops; thus 芸 means to remove weeds.
