ABSTRACT
One of the important laws in the development of Chinese vocabulary and writing is to use different spellings to distinguish the meanings of words; that is, giving several spellings to a word and assigning to them different meanings, which are originally of the same word. The period of official script was a period of rapid changes in the form of Chinese characters, which created conditions for distinguishing the meanings of words using different writing forms. Many phenomena of different forms and meanings in Chinese language and writing emerged during this period, but their origins are often unclear to future generations, as is the case with “nai” and “nai”, “shu” and “chi”, and “chen” and “formation”.
