Language is the product of the collective life of a community of people. It is a means by which people in one community communicate with people in other communities. Language not only helps in communicating, but it also helps in understanding the culture of others. In other words, the decline of a language leads to the decline of that culture. It is an inalienable part of human culture, and therefore in other words, human culture is expressed primarily through language, although there are other means of cultural expression (such as actions, gestures, body movements known as body language, etc.). Language, through expressions, can give form to various thoughts and ideas. In order to understand the culture of a society and the cultural history of a society, understanding the language of that society and that of its previous generations is a primary requirement on the part of researchers. Researchers must make do with the historical records and archaeological materials available to them for this purpose. Some researchers attempt to trace the shape and characteristics of a society's prehistoric linguistic system through conjecture, primarily based on the earliest available historical materials. Language change is an interesting subject to study for all countries and all civilizations. It doesn't matter if civilization still exists or has been banished. People living in different parts of the world speak different languages. In China, although there is a standard language, Putonghua, there are many languages ​​and dialects and it is difficult to find a lingua franca common to all. All this being the harsh reality and bare facts of the Chinese linguistic scenario, it is necessary to study what gives rise to...... middle of paper...... evolution goes through various phases. During these phases, the language changes due to the changing material situation of society. Even within the same society, there is a hierarchy based on the economic situation of individuals. Language is shaped according to the social strata of the individual's social class. For example, in Charles Dicken's novels, workers and nobles used different forms of the English language. It's not just about formal words, the style of speech and choice of words also varies depending on class differentiation. In today's England, there are still two forms of English-British and Royal English. This type of stratification is very marked in developing countries where there is a strong division of society on the basis of social classes. Different branches of linguistics believe that linguistic changes are slow and sometimes take centuries..
