殷虚卜辞“乎”字的构形理据迄今没有确切解释。从形、音、义三个方面互相推求，卜辞“乎”字应是一个形声字，形符像呼出之气，声符是“柯”字的初文，本义是呼气，卜辞中常见的呼召义不是它的本义。 There is no exact explanation so far for the tenets of the word “imaginary” in the Yin Inscriptions. From the three aspects of shape, tone and meaning, we can infer that the word “peace” should be a phonetic word, the shape of the sign is the breath of gas, and the phonetic symbol is the beginning of the word “Ke”. The original meaning is the breath, the common Righteousness is not its original meaning.
