What is the explanation of ancient and modern nouns?

Ancient and modern characters are a term in traditional exegetics. The same word is expressed in different languages in different times, forming ancient and modern characters. The former is called "ancient writing" and the latter is called "modern writing". Ancient and modern Chinese characters came into being in the Han Dynasty, but there has always been a lack of strict definition. ?

Generally speaking, modern Chinese characters use ancient Chinese characters as phonetic symbols, and an ideographic symbol is added to show the difference. For example, "wisdom" is a modern word for "knowledge" and knowledge is an ancient word. "Responsibility" is the ancient word for "debt", and "debt" is the present word.

Cause of occurrence

There were few words in the pre-Qin period, and a word often had several functions and meanings. In order not to let a word have too many part-time jobs, and to make words more accurate and perfect in the recording language, people create new words to assume a certain meaning of a word.

Chinese characters are mostly polysemous words, and no new words are created for each polysemous word to share the responsibility. Whether to make words depends on whether it affects the expression of language and whether it is necessary to make words. But this specific standard is still unclear today.
