“不”字由两部分组成。上面是一横,下面是根须状的三条线。有专家认为,这一横表示天,下面的三条线就像一只鸟。也有学者认为,“不”字上面的一横表示地面,下面部分表示种子萌发时,向地下生长的根须,因此,“不”字的本义是植物的种子,后来因被用为否定词,本义反而逐渐消失了。 “No ” is composed of two parts. Above is a horizontal, the following is a root-like three lines. Some experts believe that this horizontal shows the sky, the following three lines is like a bird. Some scholars also think that the horizontal line above the “no” character indicates the ground, and the lower part indicates the underground root that grows when the seed germinates. Therefore, the original meaning of “not” is the plant seed, For the negative word, the original meaning gradually disappeared.
