How did dialects come about, and how did they come to be?

The order in which dialects are formed (how the original dialects were formed).

Ancient dialects (the earliest dialects) can only be formed due to linguistic differentiation (a language develops and evolves independently to form different phonetic variants due to social differentiation, without the influence and fusion of other languages or sounds), and there is no factor of linguistic fusion.

Modern dialects (the final dialects) are formed by the fusion of languages (the influence and fusion of two or more languages to form phonetic variants of a language, and the formation of two or more languages together). In the process of language fusion, it is often fused with the local local language or the local local dialect, and the same language changes (vocabulary, phonetics, etc.), so that the later (modern) dialect is produced.

For example: Jiangsu, Zhejiang, Jinhua area. There is Jinhua.

Yiwu. Dongyang. Pujiang.

Pan'an. Wuyi. Lanxi and other county and city dialects.

At the bottom of these dialects are the dialects of ancient local languages that were formed as a result of linguistic differentiation. Or rather, how these dialects were formed in ancient times. The answer can only be linguistic differentiation.

Later (modern), the upper echelons of these dialects, the so-called modern dialects of these dialects (modern phonetics. vocabulary) is formed due to the fusion with Mandarin Chinese.

The order in which dialects are formed: first ancient (early) dialects due to linguistic differentiation, and then modern dialects due to linguistic fusion.

Dialects are like personal habits, in fact, this is the habit of the place, like wheat growing in a field, it is always uneven, but they are all wheat, crops are affected by the environment, and the same is true of dialects.

Regional habits, the mutual influence of different ethnic groups, and the mutual integration of ethnic languages.

In China, where the land is vast and abundant, the Chinese language, as a tool for communication between people, will have some different degrees of differentiation and unity due to differences in geographical or social factors in the process of development, and dialects will come into being. Dialect, also commonly known as local dialect or hometown dialect. It is not difficult to imagine that our country has a vast territory, a complex population, and a wide variety of dialects.

To be honest, I think the decline of official dialect and non-official dialect is not the same, the official dialect is gradually approaching Mandarin internally, and then being replaced by Mandarin; The non-official dialect is basically directly replaced by Mandarin.

The biggest experience about dialects is that you can communicate with various dialects in Mandarin without being abducted, and you don't realize that the accent is different.

Several independent languages that diverge from the same language have a homology with each other. There are certain common characteristics and correspondence in phonetics, vocabulary, and grammar. Language families, language families, and language branches are all established according to the "kinship" of the language, which is called kinship language.

From the perspective of linguistic evolution and its relationship with society, both dialects and kinship languages are related to the geographical differentiation of a single society, and they are all descendants of a single language. This is what dialects and kinship languages have in common. If the geographical differentiation of a single society is incomplete, its language is generally incomplete.

Judgment of the language of the relative.

The main basis for judging whether the descendants of the same language in different regions are dialectal or kinship linguistic relationships is the psychology of language users. If the inhabitants of all regions believe that they speak the same language as each other, then these local branch languages are dialectal relationships. If the inhabitants of different places do not think that they speak the same language, then these local branch languages are related to the languages of kinship.
