In linguistics, social dialect refers to the language used in a social group, social class or subculture group. In this sense, it is different from personal dialect, which is a special language form used by individuals.
There is no direct relationship between social dialects and regional dialects, but language differences formed by different occupations, social status, political beliefs, education levels and other factors or community communication habits formed by these factors. The main differences are language style and expression, as well as the use of some special words. For example, the Hua Er sound in Beijing dialect.
The causes of the emergence of social dialects
There are many factors in the formation of social dialects, including social, historical and geographical factors, such as long-term small-scale peasant economy, social division, population migration, mountain and river barriers and so on.
There are also factors that belong to the language itself, such as the imbalance of language development and the conflict and influence between different languages. Population migration is the most direct and important reason for the formation of dialects.
