A Chinese character. In most and normal situation, it means grass with a falling-rising tone. But it is also used in the very informal situation by young people on the internet or verbally referring to ''操'' with a falling tone. The latter has one meaning similar to F-word in English literaturely. The usage is also similar to the F-word for expressing surprising, curse, annoying ect, although it is not independently used in the middle of sentences. When it is used in the middle of the sentence, it is usually followed by the Chinese national invective, and has the function of the emphasis on the national invective. ''草'' is used because it is much less rude that ''操'', as it is only a replacement of ''操'' from the pronunciation and thus much indirect. In addition, ''艹'' is an abbreviation of ''草'' in the informal meaning because it is a Chinese character component represents the meaning of grass.
